Why Regular Oil Changes Are Crucial for Denver Drivers

April 3, 2025 by Denver Express Car Care

You’ve seen the reminder sticker in the corner of your windshield. Maybe you’ve even glanced at it a few times, thinking, I’ll get to it next week. And then next week turns into next month—and before you know it, you’re overdue for an oil change.

We get it. Life gets busy. But when it comes to car maintenance, few things are as simple or as critical as a regular oil change. If you want to keep your car running smoothly here in Denver—where elevation, temperature swings, and stop-and-go traffic all work your engine a little harder than usual—routine oil changes aren’t optional. They’re essential.

So, why do oil changes matter? What makes them especially important for Denver drivers.

What Does Engine Oil Actually Do?

An engine can’t survive without motor oil. It lubricates all the moving parts, helping everything glide rather than grind. Without clean oil, friction builds, heat increases, and your engine starts to wear down—fast.

Engine oil serves a few essential functions:

  • It reduces metal-on-metal contact, preventing premature wear.
  • It helps dissipate heat generated by your engine.
  • It picks up dirt, debris, and combustion byproducts to keep things clean.
  • It forms a seal between pistons, rings, and cylinder walls to maintain compression.
  • It adds a layer of protection against rust and corrosion.

Over time, oil breaks down and collects contaminants, which is why it needs to be replaced regularly.

How Denver Conditions Affect Your Engine Oil

Here in Denver, we like to say you can experience all four seasons in a single day. That might make for interesting weather—but it also puts unique stress on your engine and its oil.

Why Regular Oil Changes Are Crucial for Denver Drivers

High Altitude

At higher elevations, the air is thinner. Your engine has to work harder to maintain power, especially on steep inclines or during mountain driving. This extra workload means higher internal temperatures, which can cause oil to break down more quickly.

Big Temperature Swings

Denver’s climate changes rapidly—from freezing mornings to hot afternoons. These temperature swings can affect oil viscosity (how thick or thin it is), especially if you’re not using the right oil for the season or your vehicle.

Stop-and-Go Traffic

Whether you’re stuck on I-25 during rush hour or inching your way through downtown on a Saturday night, stop-and-go traffic puts added strain on your engine. Every time you idle or accelerate, you’re asking your oil to do a little more work.

Dust and Debris

With dry conditions and plenty of roadside construction, Colorado roads often come with extra dust. These particles can work their way into your engine and oil, leading to faster contamination.

How Often Should You Get an Oil Change?

This is one of the most common questions we get—and the answer depends on a few factors, including your vehicle’s make, model, age, and the type of oil you use.

Here’s a general rule of thumb:

  • Conventional oil: Every 3,000 to 5,000 miles
  • Synthetic oil: Every 7,500 to 10,000 miles

That said, Denver’s driving conditions may mean you need to be a little more proactive—especially if you:

  • Frequently drive in heavy traffic
  • Make short trips where the engine doesn’t fully warm up
  • Regularly drive into the mountains
  • Tow trailers or carry heavy loads

Not sure what’s best for your car? Check your owner’s manual—or better yet, ask one of our mechanics. We’re always happy to make recommendations based on how you drive.

What Happens If You Skip an Oil Change?

We hear this one a lot: What’s the worst that could happen if I go a little longer between oil changes?

The truth is, the effects of overdue oil changes might not be obvious right away. But over time, they can take a serious toll on your engine.

Here’s what you’re risking:

  • Engine sludge buildup – Old oil thickens and turns into sludge, which clogs your engine and restricts oil flow.
  • Overheating – Dirty or low oil can’t cool your engine properly, which can lead to overheating and warped components.
  • Increased wear and tear – Without proper lubrication, your engine’s moving parts wear out faster.
  • Reduced fuel efficiency – An engine that’s working harder burns more fuel.
  • Costly repairs – Ignoring oil changes can lead to serious engine damage, and in some cases, complete engine failure.

In other words, skipping an oil change to save time or money usually ends up costing more of both.

Signs You Might Be Overdue for an Oil Change

Even if you lose track of mileage, your car might be sending you signals. Keep an eye (and ear) out for these signs:

  • Dark, dirty oil on the dipstick
  • Knocking or ticking noises from the engine
  • Oil warning light on your dashboard
  • Exhaust smoke that looks darker than usual
  • Burning oil smell inside the car
  • Poor performance or reduced gas mileage

If you’re experiencing any of these symptoms, it’s time to schedule an oil change as soon as possible.

The Benefits of Using High-Quality Motor Oil for Your Engine

February 28, 2025 by Denver Express Car Care

What’s the one rule about car maintenance they press on you like no other? Change your motor oil!

There’s a reason for that. Without motor oil, your car won’t go. It’s the most important fluid in your car’s engine; it’s what keeps your car in good running condition. 

It lubricates moving parts, reduces friction, and helps regulate temperature. But not all motor oils are created equal. Using a low-quality or incorrect oil can lead to excessive wear, poor fuel efficiency, and even engine failure over time.

So, what makes high-quality motor oil different? Why does it matter? And how can you ensure you’re using the best oil for your vehicle?

What Does Motor Oil Do for Your Engine?

Even if you don’t know much about auto mechanics, you should understand that the engine is at the heart of every vehicle. It’s a complex machine with many moving parts, all working together at high speeds and temperatures. 

The Benefits of Using High-Quality Motor Oil for Your Engine

That’s where motor oil comes into play. Motor oil has several critical roles:

  • Lubrication: Reduces friction between metal components, preventing premature wear.
  • Heat Regulation: Helps dissipate heat generated by the combustion process.
  • Contaminant Removal: Traps dirt, debris, and combustion byproducts, preventing sludge buildup.
  • Corrosion Protection: Coats metal surfaces to prevent rust and oxidation.
  • Sealing Performance: Helps maintain proper sealing between pistons and cylinder walls.

That’s a lot of work! If you take nothing else away from this, just remember your engine can’t function properly without motor oil. 

Yet just because oil is in your engine doesn’t mean it’s doing the best possible job.

The Difference Between High-Quality and Low-Quality Motor Oil

If you’ve ever browsed the motor oil section at an auto parts store, you know the choices can be overwhelming. Synthetic, conventional, high-mileage, full synthetic—what’s the difference?

High-quality motor oil is engineered with superior base oils and additives that enhance performance. Here’s how it stands apart from lower-quality options:

  • Better Viscosity Control: High-quality oils maintain their thickness and lubrication properties across a wide range of temperatures. Cheap oils tend to break down faster, leading to poor lubrication.
  • Superior Detergents & Additives: Premium oils contain detergents that clean the engine and prevent sludge buildup. Lower-quality oils often lack these additives, leading to dirty engine internals.
  • Oxidation Resistance: Heat and oxygen can cause oil to break down over time. High-quality oils resist oxidation better, extending the life of your oil and engine.
  • Lower Volatility: Lower-quality oils can burn off more quickly, leading to higher oil consumption and deposits inside the engine.

Choosing the right motor oil isn’t just about meeting your car’s basic needs—it’s about optimizing performance, longevity, and efficiency. Of course, it’s not as easy as just picking one that sounds good. Your car has different needs. And you put your car in different driving conditions, which means there are certain oils better for the way you drive. 

Still, it is important to choose a high-quality motor oil to ensure the long life for your vehicle. 

Benefits of Using High-Quality Motor Oil

Extends Engine Life

Engines experience constant wear and tear, but high-quality oil provides a layer of protection that minimizes friction and reduces premature wear. The better the oil, the better your engine is protected from internal damage, meaning fewer costly repairs down the road.

Improves Fuel Efficiency

Proper lubrication helps your engine run more efficiently, reducing the energy required to move internal components. Less friction means less wasted fuel, leading to better gas mileage. If you want to save money at the pump, choosing high-quality motor oil is a simple way to improve efficiency.

Keeps Your Engine Cleaner

Dirt, debris, and byproducts from combustion can create sludge inside your engine, reducing efficiency and clogging vital components. High-quality motor oil contains detergents that actively clean the engine, preventing buildup and maintaining peak performance.

Reduces Risk of Overheating

Engines generate a lot of heat, and your oil plays a crucial role in keeping temperatures under control. Poor-quality oil can break down under high heat, leading to excessive engine wear and even overheating. High-quality motor oils are formulated to withstand extreme temperatures, ensuring your engine stays cool.

Enhances Cold-Weather Performance

If you’ve ever had trouble starting your car on a freezing morning, poor-quality oil might be part of the problem. Low-quality oil thickens in cold temperatures, making it harder for your engine to turn over. High-quality oils maintain their fluidity, allowing for easier starts and immediate lubrication, even in winter conditions.

Provides Better Protection for Turbocharged Engines

Turbocharged engines are becoming more common in modern vehicles, but they require extra care. These engines operate at higher temperatures and pressures, meaning they need superior lubrication to avoid damage. High-quality synthetic oils are specifically designed to handle the demands of turbocharged engines, preventing premature wear and oil breakdown.

Reduces Harmful Emissions

Using low-quality oil can lead to more deposits in the engine, increasing emissions and reducing overall efficiency. High-quality oil keeps the engine cleaner, reducing harmful emissions and helping your car run more smoothly.

How to Choose the Right High-Quality Motor Oil

Now that you know why high-quality oil matters, how do you choose the best one for your car?

Check Your Owner’s Manual

This is your best place to start. Every vehicle manufacturer provides oil recommendations based on engine design. Look for the correct viscosity (e.g., 5W-30, 10W-40) and whether synthetic or conventional oil is required. Or talk with one of our mechanics. They can make suggestions too. 

Choose Synthetic Over Conventional

Synthetic oils outperform conventional oils in nearly every category, including lubrication, heat resistance, and longevity. While they cost more upfront, they provide better protection and require fewer oil changes. Again, we can chat with you about suggestions. It depends on your driving habits, your car, and what’s best for your unique situation.  

Consider High-Mileage or Performance Oils

If your car has over 75,000 miles, high-mileage motor oils contain additives that condition seals, prevent leaks, and reduce wear. If you drive a performance vehicle, synthetic performance oils are designed to handle higher RPMs and extreme conditions. Have questions? Let’s talk. 

How Often Should You Change High-Quality Motor Oil?

Even the best oil doesn’t last forever. While high-quality synthetic oils can last longer than conventional oils, it’s still essential to change your oil regularly.

  • Conventional oil: Every 3,000–5,000 miles
  • Synthetic blend: Every 5,000–7,500 miles
  • Full synthetic: Every 7,500–10,000 miles

This is a guesstimate. We always suggest erring on the side of lower mileage. It’s that important to the longevity of your car. If you frequently drive in stop-and-go traffic, tow heavy loads, or operate in extreme temperatures, consider changing your oil more frequently.

Invest in High-Quality Motor Oil for Long-Term Benefits

Motor oil is one of the most important fluids in your car, yet it’s often overlooked. If it’s time for an oil change or you’re unsure which motor oil is right for your car, schedule an appointment with us today. Our team of expert mechanics can help you choose the best oil for your vehicle, ensuring it stays in peak condition for years to come.

Because when it comes to protecting your engine, quality matters.

The Role of Regular Oil Filter Replacements

October 7, 2024 by Denver Express Car Care

What keeps a car in good working condition? Many would say it’s the frequent oil changes. 

Every part of your car plays a role in keeping it running smoothly. Some would definitely point to oil changes. But there’s another small part that works just as hard and is equally important: the oil filter.

Oil filter replacements are often overlooked, but they’re critical to your engine’s health. If you’re wondering why regular oil filter replacements matter so much, you’re in the right place. We want to help you discover the importance of keeping your oil filter in good shape and how it impacts the overall performance of your car.

What Does an Oil Filter Do?

Oil is literally the lifeblood of your vehicle. It lubricates engine parts, reduces friction, and helps dissipate heat. 

But as the oil circulates through the engine, it picks up dirt, debris, and metal particles from normal engine wear. This is where the oil filter comes in. Its job is to remove contaminants from the oil before it circulates back through the engine, keeping everything running clean and smooth.

Without an oil filter, those contaminants would circulate with the oil, causing:

  • Increased engine wear: Tiny particles in the oil act like sandpaper, slowly wearing down engine parts.
  • Clogged oil passages: Debris can block critical oil passages, restricting the flow of oil.
  • Reduced engine efficiency: Dirty oil can cause sludge buildup, which negatively impacts engine performance and fuel efficiency.

Why Regular Oil Filter Replacements Are Necessary

Your oil filter is designed to trap dirt and debris, but it doesn’t last forever. Over time, it gets clogged with contaminants and becomes less effective. If you don’t replace your oil filter regularly, it can lead to several issues:

The Role of Regular Oil Filter Replacements
  • Restricted oil flow: As the filter becomes clogged, less oil can pass through, reducing lubrication and increasing friction in the engine.
  • Dirty oil recirculation: When the filter is clogged, dirty oil may bypass the filter entirely, circulating contaminants through your engine.
  • Engine damage: Running your car with a clogged or ineffective oil filter increases the risk of long-term engine damage.

In short, a clean oil filter is essential for keeping your engine running smoothly and extending its life. Considering the price and how easy it is to replace, this should be an automatic part of your regular routine. Luckily, it’s a service we offer with our full service oil changes. 

How Often Should You Replace Your Oil Filter?

Some would argue that oil filters can last a while. We feel it depends on several factors, including your driving habits, the type of oil you use, and your vehicle’s specifications. But as a general rule, oil filters should be replaced every time you change your oil.

Most vehicles require an oil change every 3,000 to 7,500 miles, but if you use synthetic oil, you might be able to go longer between changes—up to 10,000 miles. This is where it pays to get to know your owner’s manual. It can guide you to the manufacturer’s recommended oil change intervals, and give you an idea of when it’s time to replace the oil filter.

Signs It’s Time to Replace Your Oil Filter

Even if you’re diligent about oil changes, it’s still important to be aware of the signs that your oil filter might need replacing. Here are some things we recommend watching for:

  • Oil pressure warning light: If your oil pressure warning light comes on, it could be a sign that your oil filter is clogged and restricting oil flow.
  • Dirty oil: If the oil on your dipstick looks thick, dark, or gritty, it’s a sign that your filter isn’t doing its job and needs to be replaced.
  • Engine overheating: A clogged oil filter can reduce oil circulation, leading to increased friction and heat in the engine.
  • Sputtering or poor performance: If your car’s engine feels sluggish or you notice performance issues, a clogged oil filter could be to blame.

Any of these signs is an indication it’s a good idea to get your oil filter checked and replaced as soon as possible.

Benefits of Regular Oil Filter Replacements

Hopefully you now have a better understanding of the signs of a bad oil filter. It’s not always crystal clear, but with these ideas in mind, you’re more likely to sense an issue in its early stages. 

If you’re still not convinced of the benefits of replacing it regularly, let’s look at some reasons why. While it may seem like a small task, it offers big rewards in terms of your car’s performance and longevity.

Better Engine Performance

Your car’s engine works hard, and it needs clean, filtered oil to perform at its best. Replacing your oil filter regularly ensures that only clean oil is circulating through the engine, helping it run more smoothly and efficiently. You’ll notice better acceleration, smoother driving, and improved fuel efficiency when your engine is running on clean oil.

Extended Engine Life

The cleaner your engine stays, the longer it will last. Replacing your oil filter keeps harmful contaminants from circulating in the oil and causing damage to engine parts. By keeping your oil filter in good condition, you’ll help extend the life of your engine, saving you from costly repairs down the road.

Reduced Risk of Costly Repairs

Engine repairs can be expensive, and ignoring simple maintenance tasks like oil filter replacements can lead to bigger problems. A clogged or ineffective oil filter can cause engine damage that’s costly to fix. Replacing the filter regularly is an inexpensive way to protect your engine from more expensive issues later on.

Improved Fuel Efficiency

Clean oil reduces friction in the engine, helping it run more efficiently. When your oil filter is clogged, the engine has to work harder, which leads to decreased fuel efficiency. Replacing your oil filter can help you get better gas mileage and save money at the pump.

Choosing the Right Oil Filter for Your Car

Not all oil filters are created equal. When it’s time to replace your oil filter, here’s what you should consider:

  • Check your owner’s manual: Your car’s manufacturer will recommend the specific type of oil filter that works best for your vehicle.
  • Consider your driving habits: If you frequently drive in harsh conditions, like stop-and-go traffic or extreme temperatures, you may want to opt for a high-performance oil filter designed to handle those conditions.
  • Stick with quality brands: Don’t skimp on the oil filter. Investing in a quality filter from a reputable brand will offer better protection for your engine.

Why Regular Oil Changes are Essential for Your Vehicle

July 3, 2024 by Denver Express Car Care

You’re familiar with the advice about regular oil changes. It’s why oil changes are the most frequent maintenance items performed on today’s vehicles. 

What you aren’t sure about is the why. 

They say to replace oil every 3,000 to 5,000 miles. Some push it to 7,500 or 10,000. But what’s really true? Are regular oil changes essential to the health of your vehicle? What should you keep in mind as you go about your errands each day?

Why Your Car Needs Motor Oil

Your car’s engine needs motor oil to keep it running smoothly. It provides lubrication. Without it, the moving parts inside the engine couldn’t glide together without causing damage. They would grind, creating a lot of friction and wear. 

Motor oil also plays a crucial role in cooling the engine. As the engine runs, it gets hot, and the oil helps carry away this heat. This keeps the engine from overheating and maintains the right temperature for proper operation.

This role means motor oil gets pushed to the limit as you drive each day. Luckily, manufacturers realize this, and have built special additives into motor oil to pick up debris, and sludge, preventing them from building up inside the engine. This keeps the engine clean and running efficiently.

Without motor oil, an engine could face corrosion. Motor oil forms a protective layer on engine parts, preventing rust and damage caused by moisture and other elements. This is vital for keeping the engine in good condition.  It seals the engine, filling the tiny gaps between the piston rings and cylinder walls, ensuring efficient compression and combustion. This improves how the engine performs and helps save on fuel.

Why Regular Oil Changes are Essential for Your Vehicle

And if all that wasn’t enough, it also acts as a shock absorber. It cushions the engine’s moving parts, reducing the noise and vibration you might feel while driving. This makes your ride smoother and quieter.

What’s In Regular Motor Oil That Makes It Essential For Your Vehicle

Motor oil is essential to keep your car’s engine performing throughout the years. But what’s even more important is understanding what’s inside. 

The primary component of motor oil is the base oil, which makes up about 70-90 percent of the oil. Base oils can be made from petroleum, synthetic chemicals, or a blend of both. They provide the basic lubrication properties needed to reduce friction and wear in the engine.

The remaining 10-30 percent of motor oil consists of additives that enhance the performance of the base oil. These additives include:

Detergents

Detergents keep the engine clean by preventing the formation of deposits, sludge, and varnish on engine parts. They help remove impurities and keep them suspended in the oil until the next oil change.

Dispersants

Dispersants help keep solid contaminants in suspension, preventing them from clumping together and forming sludge. This ensures that the contaminants are carried to the oil filter, where they can be removed from circulation.

Anti-Wear Agents

Anti-wear agents, such as zinc dialkyl dithiophosphate (ZDDP), form a protective film on engine parts. This film reduces metal-to-metal contact, thereby minimizing wear and extending the life of engine components.

Viscosity Index Improvers

These additives help the oil maintain its viscosity, or thickness, across a wide range of temperatures. This ensures that the oil flows easily at low temperatures while remaining thick enough to provide adequate lubrication at high temperatures.

Antioxidants

Antioxidants prevent the oil from oxidizing, or breaking down, under high temperatures. Oxidation can lead to the formation of sludge and varnish, which can harm the engine. By preventing oxidation, antioxidants help prolong the life of the oil.

Corrosion Inhibitors

Corrosion inhibitors protect the engine parts from rust and corrosion caused by moisture and acidic by-products of combustion. This protection helps maintain the integrity of engine components.

Friction Modifiers

Friction modifiers reduce friction between moving parts, improving fuel efficiency and reducing wear. They are particularly important in modern engines designed for high performance and fuel economy.

Foam Inhibitors

Foam inhibitors prevent the formation of foam and air bubbles in the oil. Foam can reduce the oil’s effectiveness in lubricating and cooling the engine, so these inhibitors ensure consistent performance.

What Makes Today’s Motor Oil Different From Yesteryear?

Motor oil has been used since the dawn of cars. Maybe you remember your dad performing an oil change himself – it seemed easy. Just a can of oil, and you’re on your way. 

Things have changed a bit over the years. Today’s motor oil significantly differs from the oil used in the past. 

Modern motor oils often include synthetic base oils, which are chemically engineered to provide superior performance compared to conventional petroleum-based oils. Synthetic oils offer better stability, reduced volatility, and enhanced performance at extreme temperatures. Even conventional oils have seen improvements in refining processes, resulting in cleaner, more stable base oils that perform better and last longer.

Today’s motor oils also contain a more sophisticated blend of additives designed to meet the specific needs of modern engines. These include advanced detergents, dispersants, anti-wear agents, antioxidants, and friction modifiers that provide better protection and performance. Additives are now tailored to meet the requirements of different types of engines, including turbocharged, direct-injection, and high-performance engines.

Modern oils are typically multi-grade, meaning they can perform well across a wide range of temperatures. This is achieved through viscosity index improvers that allow the oil to remain fluid in cold temperatures while maintaining its thickness in hot conditions. They are more stable and less prone to breaking down or thinning out under extreme conditions, providing consistent lubrication and protection.

Modern motor oils meet stringent standards set by organizations like the American Petroleum Institute (API) and the European Automobile Manufacturers’ Association (ACEA). These standards ensure that the oils provide adequate protection and performance for modern engines. Many motor oils are also formulated to meet the specific requirements of Original Equipment Manufacturers (OEMs), ensuring compatibility and optimal performance for specific vehicle brands and models.

There is a growing market for biodegradable and eco-friendly motor oils that are less harmful to the environment. These oils are designed to minimize the ecological impact without sacrificing performance.

That’s Why Regular Oil Changes Are More Important Than Ever

It’s easy to put off regular maintenance. You get busy. Life happens. And suddenly, you can’t remember the last time you brought your vehicle in for servicing. 

But there’s a reason it can’t wait. Your engine is at the heart of your vehicle. If it’s compromised, it can have a ripple effect throughout your vehicle. 

Want to increase longevity? Want your vehicle to continue running smoothly? Start with a regular oil change. 

It’s the start of keeping your vehicle in the best shape possible.

Oil Change Frequency: Debunking Myths and Setting the Record Straight

March 24, 2024 by Denver Express Car Care

What do you know about motor oil? Chances are, it has to do with oil change frequency. 

Marketing pounds the frequency concept through flyers, postcards, and television ads. 

“Get your oil changed every 3,000 miles … or else!” 

Or else, what? 

Maybe you’re the type of driver who changes motor oil every 3,000 miles. You have a sticker reminder in your window, and you make it a part of your regular routine. 

Or maybe you’re the driver who wonders if it’s necessary. 3,000 miles happened a bit ago. You’re pushing it … that’s okay, right?

Let’s dive into the nitty gritty of motor oil frequency and other myths you might believe. 

The biggest myth – oil change frequency

Once upon a time, changing motor oil frequently was vitally important to the performance of your car. The general rule was that engine oil needed to be changed every 3,000 miles or three months, whichever came first.

This notion has been perpetuated for decades by oil change shops, mechanics, and even some car manufacturers. However, advancements in both oil technology and engine design have rendered this myth obsolete for most modern vehicles.

Oil Change Frequency: Debunking Myths and Setting the Record Straight

Modern synthetic oils, along with improvements in engine manufacturing and design, have significantly extended the interval at which oil changes are necessary. For many vehicles, the recommended oil change interval now falls between 5,000 to 10,000 miles, depending on driving conditions and the type of oil used. Some newer vehicles even have oil life monitoring systems that calculate the optimal oil change interval based on driving habits and conditions.

Should you still adhere to the 3,000-mile myth? Not necessarily. A lot of it depends on your vehicle. 

Check with your owner’s manual. The make and brand of your vehicle will dictate a schedule you can adhere to. While many would say to err on the side of more frequent changes to ensure a well-performing car, there is one thing to consider. 

Continuing to adhere to the outdated 3,000-mile rule can be unnecessarily costly and environmentally harmful. Frequent oil changes contribute to the generation of used oil waste, as well as unnecessary resource consumption. Moreover, it places an undue financial burden on car owners, who may be spending more money on oil changes than is necessary.

Start with your owner’s manual as guidance. Then speak with one of our mechanics. We’ll help you form a solid oil changing schedule you can live with, and that will keep your car in peak performance. 

All the myths around synthetic motor oil

Depending on where you get your information, you’ll likely find a host of myths that involve synthetic motor oil:

  • Synthetic oil causes leaks
  • Synthetic oil is too “slippery” for older engines
  • Synthetic oil extends oil change intervals indefinitely
  • Synthetic oil is only for high-performance vehicles
  • Synthetic oil is too expensive
  • Once you use synthetic oil, you can never go back

Have you fallen for any of these yourself?

Synthetic motor oil is a lubricant for internal combustion engines that is artificially created through a process called synthesis. Unlike conventional motor oil, which is derived from crude oil through refining processes, synthetic motor oil is chemically engineered to have specific molecular properties that enhance engine performance and protection.

The synthesis process starts with base oils, which can be either chemically synthesized or derived from crude oil. These base oils are combined with various additives to achieve the desired characteristics, such as viscosity, thermal stability, and resistance to oxidation and breakdown. And they provide a host of benefits, such as better performance, improved engine protection, and extended fuel efficiency.

Sounds like synthetic motor oil may be perfect for you, not matter what you drive. Yet the myths persist. 

One persistent myth is that switching to synthetic oil can cause older engines with worn seals to develop leaks. However, synthetic oils are formulated to be compatible with seals and gaskets in both new and older engines. In fact, synthetic oils often have superior sealing properties compared to conventional oils, reducing the likelihood of leaks.

Or maybe you’ve heard the myth that synthetic oil is only necessary for high-performance or luxury vehicles. While it’s true that synthetic oil can offer significant benefits in high-stress situations, such as racing or towing, it’s suitable for use in all types of vehicles. Synthetic oils provide better protection against engine wear, improved fuel economy, and enhanced performance, making them a beneficial choice for any vehicle.

You can switch between regular (conventional) and synthetic motor oil in your vehicle, and it’s a relatively common practice. However, there are a few things to consider when making the switch, such as compatibility and the benefits of synthetic oil for your vehicle.  

Should you be using synthetic motor oil? Check your owner’s manual. Then have a conversion with one of our mechanics. 

A few myths around motor oil additives

Motor oil isn’t a pure liquid product. Today’s motor oil contains a variety of additives, chemical compounds that are mixed with base oils to enhance the performance and properties of motor oil. These additives serve various functions and are carefully formulated to address specific needs and challenges associated with engine lubrication.

You’ll find detergents to help prevent the buildup of deposits, sludge, and varnish in the engine by keeping contaminants suspended in the oil. Dispersants work in conjunction with detergents to suspend and disperse contaminants in the oil, preventing them from settling on engine surfaces. Anti-wear additives form a protective film on metal surfaces, reducing friction and wear between moving engine parts. Viscosity index improvers (VIIs) are polymers added to motor oil to improve its viscosity-temperature characteristics. 

This is what makes shopping for motor oil a little confusing. What should you choose? Which is best for your vehicle?

Prolonging Engine Life, One Drop of Motor Oil at a Time

February 4, 2024 by Denver Express Car Care

When you buy a new car, you have hopes for a long life. On average, people hold onto their vehicles for over 9 years, longer for some of the more popular models.

But to keep a car that long, you’ll need a maintenance schedule to get you through.

Ask 10 people what the most important system is on a car, and you’ll likely get 10 different answers. Try functioning without brakes or steering. Few would argue that an exhaust system is critical in modern society.

Yet if your goal is to prolong engine life, you can only do that one drop of motor oil at a time. Oil is vital for keeping your car’s engine running smoothly. If you don’t use the correct motor oil for your car’s system, you’ll know it in very short order.

The Importance of Regular Oil Changes

Regular oil changes are one of the most essential aspects of vehicle maintenance. While it may seem like a minor detail, neglecting to change your oil regularly can lead to significant problems with your car’s engine and overall performance.

Prolonging Engine Life, One Drop of Motor Oil at a Time

Over time, oil breaks down and becomes less effective at lubricating these components. This can lead to increased friction and wear on the engine, reducing its performance and longevity. Regular oil changes ensure the engine is properly lubricated, reducing friction and allowing it to run smoothly and efficiently.

As the oil circulates through the engine, it picks up these impurities and carries them away, preventing them from settling and causing damage. However, as the oil ages, it becomes thicker and less effective at cleaning. Regular oil changes help maintain a clean engine, preventing the buildup of harmful deposits and extending the life of your vehicle.

Oil also serves as a coolant for the engine. It helps dissipate the heat generated during combustion by carrying it away from hot engine parts. Over time, the oil can become contaminated with debris and lose its ability to effectively cool the engine, leading to overheating. Regular oil changes ensure that the fresh, clean oil is circulating properly, effectively cooling the engine and preventing the risk of overheating.

Using clean, fresh oil can help improve fuel efficiency. When the engine is well-lubricated and running smoothly, it requires less energy to operate, resulting in better fuel consumption. Regular oil changes help maintain the engine’s efficiency, potentially saving you money on fuel costs in the long run.

Perhaps one of the most significant benefits of regular oil changes is prolonging your engine’s life. By keeping the engine properly lubricated, clean, and cool, you reduce the risk of damage and wear on critical engine components. This promotes the overall health of your vehicle, helping it perform optimally for a longer period.

Signs that Indicate Your Engine Needs an Oil Change

Fresh motor oil is essential. Few would argue that point. But when should you change it? Is there a magic number? Is the rule “every 3,000 to 5,000 miles” correct?

We will say it’s better to err on the side of frequency. Because of its importance to your overall vehicle performance, being overly cautious is never a bad thing.

However, there are signs that indicate it’s time for an oil change.

  • Dark and Dirty Oil – Over time, the oil accumulates contaminants, such as dirt, debris, and engine by-products like carbon deposits. As a result, the oil loses its ability to lubricate effectively, and its viscosity may decrease. If you notice that the oil on the dipstick is dark and dirty, it’s a clear indicator that it’s time for an oil change.
  • Engine Knocking Sounds – If you hear strange and persistent knocking or ticking sounds from your engine, it may be due to insufficient lubrication. When the engine oil breaks down, it loses its ability to lubricate and protect the moving components. The lack of proper lubrication can create friction between the metal parts, resulting in knocking or tapping noises.
  • Low Oil Level – If you regularly check your oil level and notice that it is consistently low, even after adding the recommended amount, it could be an indication of a leak or excessive oil consumption. In such cases, it’s essential to get an oil change and have your vehicle inspected by a professional mechanic to diagnose and rectify the issue.
  • Increased Engine Noise – As oil becomes old and contaminated, it loses its ability to reduce friction and dampen noise. Increased engine noise could be a sign that the oil is no longer effectively lubricating the engine parts. Changing the oil will help reduce noise and improve the engine’s performance.
  • Unusual Exhaust Smoke – Thick, dark smoke may indicate that the engine oil is burning and mixing with the fuel, potentially due to oil leaks or oil that has lost its viscosity. This issue requires immediate attention and an oil change to prevent further damage to the engine.
  • Decreased Fuel Efficiency – As oil deteriorates, it loses its ability to reduce friction, increasing resistance within the engine, and causing it to work harder. This extra strain can lead to decreased fuel efficiency. Changing the oil will help optimize your engine’s performance and improve fuel economy.

Proper Oil Maintenance and Its Impact on Engine Longevity

You’ve purchased a car. You take care of it. You hope it has a long life.

You also understand that prolonging engine life is going to take a little work on your part. That’s where regular maintenance comes into play.

Engine oil plays a crucial role in lubricating the various moving parts of the engine, reducing friction, and preventing wear and tear. Regularly changing and monitoring your oil can significantly extend the life of your engine and save you from costly repairs down the line.

It’s not complicated. In fact, it’s one of the easiest chores on your to-do list. Simply schedule an oil change regularly, knowing you’ll be setting the stage for better performance.

Your car will thank you. You’ll be rewarded with a better performing car, better gas mileage, and a smoother ride.

Your vehicle is one of your most significant investments. If you have hope to keep it 8+ years, adding new motor oil periodically is the easiest form of protection.

Let’s Debunk Oil Change Myths

December 24, 2023 by Denver Express Car Care

I met a friend for lunch today. She couldn’t linger after the bill came; she had a long list of things to get done. Groceries. Run her son to soccer practice. The everyday chores we all have on a busy day. Then she turned, to-do list in hand, and said, “Oh yeah, I guess I have to get an oil change. I keep putting it off …”

Your car needs motor oil in the same way it needs gasoline. If you fail to fill the gas tank, your car won’t operate. If you forget to change the motor oil, your engine will eventually cease. 

We can’t forget gas. Our cars will let us know pretty quickly. Motor oil takes a bit longer. 

Maybe that’s why we tend to believe some of the myths around motor oil. Like if it’s really necessary to get an oil change every 3,000 to 5,000 miles. Is that true? 

Let’s dive in and look at some of the most common oil change myths, and discover what you should do to protect your vehicle. 

Oil change myth #1: An oil change is necessary every 3,000 miles

In the past, the 3,000-mile rule made sense when conventional oils and engine technology were less advanced. However, with modern vehicles and synthetic oils, this myth has become outdated and, more importantly, costly. Here’s the reality:

Let’s Debunk Oil Change Myths

The Truth: Follow your vehicle manufacturer’s recommendations.

Modern vehicles are designed to run efficiently with longer intervals between oil changes. In fact, most car manufacturers and oil experts recommend changing the oil every 7,500 to 10,000 miles, and some high-performance synthetic oils can extend that interval even further. When in doubt, refer to your manufacturer’s guidance and check your owner’s manual for more details. 

Oil change myth #2: Change your oil before a road trip

It’s a well-intentioned belief—many drivers think that changing their oil before a road trip is a precautionary measure to ensure their vehicle performs optimally during long journeys. However, in most cases, this belief is more rooted in tradition than practicality.

The Truth: Timing is key, not just mileage.

While regular oil changes are crucial for maintaining a healthy engine, changing the oil right before a road trip may not be necessary if you’ve recently had a scheduled maintenance service. What matters most is the timing of your last oil change relative to your vehicle’s recommended intervals.

Oil change myth #3: The oil filter should be replaced at every oil change

For years, many drivers have thought that changing the oil filter with every oil change is a non-negotiable practice. However, the truth lies in understanding the purpose of the oil filter and how it functions within the context of regular vehicle maintenance.

The Truth: Oil filters have a lifespan.

Oil filters are crucial in trapping contaminants and debris, preventing them from circulating through the engine and causing damage. While they are effective, it’s important to recognize that most modern oil filters are designed to last longer than a single oil change interval.

Just like oil change intervals, automobile manufacturers provide guidelines for oil filter replacement in the owner’s manual. These guidelines are often tied to specific mileage or time intervals. High-quality oil filters, especially those designed for extended use, can efficiently capture and retain contaminants over an extended period. Choosing a reputable brand and type of oil filter can contribute to longer service intervals. Trust a reliable mechanic to help you along.

Oil change myth #4: Only use one type of oil forever

Many drivers have grown up with the belief that once you find the right oil for your vehicle, you should stick with it indefinitely. However, advancements in engine technology and the availability of various oil formulations challenge this long-standing belief.

The Truth: Adaptability to changing needs.

Modern engines are designed to be more versatile and can often accommodate different types of oils depending on driving conditions, climate, and the engine’s age. While it’s crucial to choose an oil that aligns with your vehicle’s requirements, exclusive loyalty to a single type may not be necessary.

There are different types of oils, including conventional, synthetic, and blends. Each type has its own set of advantages and is formulated to address specific needs. For instance, synthetic oils offer superior high-temperature stability and overall engine protection. Check your vehicle’s owner’s manual for the manufacturer’s recommended oil specifications. Many modern engines can benefit from various oil formulations, allowing you to adapt to changing driving conditions and seasons. If you frequently experience extreme temperatures, stop-and-go traffic, or engage in heavy towing, you may need an oil formulation that offers enhanced protection under these specific conditions.

Oil change myth #5: Thicker oil is always better

Many car owners have been led to believe that using thicker oil will enhance their engine’s protection, especially in older or high-mileage vehicles. However, the truth lies in understanding the delicate balance between oil viscosity and engine specifications.

The Truth: Optimal viscosity for engine health.

While oil viscosity is a critical factor in engine protection, the belief that thicker oil is universally superior is inaccurate. The optimal viscosity depends on various factors, including the vehicle’s design, engine specifications, and operating conditions. Thicker oils may be beneficial in extreme temperatures, providing better lubrication in high-temperature conditions. However, using excessively thick oil in moderate climates can hinder engine efficiency and fuel economy.

Oil change myth #6: Synthetic oil leaks more

For years, some car owners have been hesitant to make the switch to synthetic oil due to the fear that it might cause an increase in leaks. However, this myth is rooted more in misinformation than actual evidence.

The Truth: Synthetic oils and engine seals.

Synthetic oils, known for their superior lubrication properties and stability, are designed to meet or exceed the specifications set by vehicle manufacturers. The misconception about increased leaks likely arises from  misunderstanding the relationship between synthetic oils and engine seals. High-quality synthetic oils are formulated to be fully compatible with engine seals and gaskets. In fact, many synthetic oils contain additives that can condition and rejuvenate seals, reducing the risk of leaks. Synthetic oils offer enhanced stability at high temperatures, reducing the likelihood of oil breakdown and the formation of deposits that can contribute to leaks.

Oil change myth #7: Once you switch to synthetic oil, you have to stick with it

For many car owners, transitioning from conventional to synthetic oil comes with a perceived permanence. However, this myth limits flexibility and doesn’t consider the evolving needs of both your vehicle and advancements in lubrication technology.

The Truth: Fluid compatibility and gradual transitions.

Switching between oil types, including returning to conventional oil after using synthetic, is generally acceptable and won’t harm your engine. Both traditional and synthetic oils are compatible with each other, and modern engines are designed to handle different oil formulations. Modern engines are built to hold various oil formulations. If your vehicle initially used conventional oil and you switch to synthetic, or vice versa, the engine should adapt without negative consequences. Check with your owner’s manual for more details. 

Oil change myths … debunked

Does this change your opinions or beliefs on oil changes? Modern-day vehicles are designed to be forgiving, and create a reliable driving experience every time you slip behind the wheel.

Are Additives In Motor Oil Important?

December 21, 2023 by Denver Express Car Care

You know car maintenance is important. Some projects easily filter into your to-do list – you no longer have to think about them. 

Like stopping for gas. Or ensuring your tires are properly pressurized. 

Or changing the motor oil. 

Most of us stop for an oil change when the little sticker in the window tells us we’ve reached a specific mileage. But have you ever stopped to think about why? Or what’s in motor oil that makes it beneficial for your vehicle? (Yes, motor oil additives are essential!)

Let’s dig in!

This is why your car needs motor oil

Motor oil is also referred to frequently as engine oil. It’s a lubricant used in internal combustion engines to reduce friction and wear between moving parts. 

It’s designed to lubricate the engine components, such as the pistons, bearings, and camshaft, to ensure smooth operation and minimize friction-related heat. It also helps:

  • Dissipate heat generated during engine operation, preventing components from overheating.
  • Keep the engine clean by carrying away contaminants and deposits, preventing sludge build-up and maintaining engine cleanliness.
  • Form a film between the moving parts, helping to create a seal and prevent leaks.
  • Provides a protective layer to prevent corrosion of engine components.

Now imagine what would happen if you didn’t add motor oil regularly. 

Are Additives In Motor Oil Important?

Every part would be impacted. The friction and wear would occur gradually over time as each part moved a little slower, and didn’t work quite as designed. 

More friction means more heat. If you drive a lot and this continues, heat may build and lead to overheating. And that can bring a lot of problems inside the engine compartment. 

This doesn’t happen quickly. Instead, it’s a slow build-up of sludge, dirt, and debris, gradually contaminating the motor oil and negatively impacting the engine. Which leads to poor fuel efficiency, increased emissions, more costly repairs, and eventual engine failure. 

Whew! 

All from not paying attention to your motor oil. Who knew a little can of motor oil could do so much for your car. 

What’s in a can of motor oil?

Here’s where it gets interesting. Motor oil is more than just another liquid. 

New, clean motor oil is typically amber or light brown. However, as it ages and accumulates contaminants, it can darken and appear black. The color can also be influenced by the additives and base oil used in the formulation. High-quality synthetic oils may have a clearer, lighter color.

You may notice its mild, characteristic petroleum odor. However, as oil ages and accumulates contaminants, it may develop a stronger, more unpleasant smell. The presence of burnt or acrid odors could indicate overheating or other issues within the engine.

Motor oil is designed to have a specific viscosity, which is a measure of its thickness or resistance to flow. It’s often labeled with two numbers, such as 10W-30. The first indicates the oil’s viscosity at low temperatures, while the second indicates the viscosity at high temperatures. The consistency can range from relatively thin to more viscous, depending on the oil’s intended use and operating conditions. 

What’s in motor oil? It can vary depending on the specific formulation, brand, and intended use (conventional, synthetic, or a blend). However, motor oil typically consists of a base oil and additives. Here’s what’s in each:

Base Oil

The base oil is the primary component of motor oil and makes up the majority of its volume. It can be derived from crude oil or synthesized chemically. The base oil provides the lubricating properties necessary to reduce friction and wear between moving engine parts. The quality and type of base oil (conventional, synthetic, or semi-synthetic) significantly influence the performance of the motor oil.

Additives

Motor oil contains various additives to enhance its performance and provide additional benefits. These additives include:

  • Detergents and Dispersants – These additives help keep the engine clean by preventing the formation of deposits and sludge. They disperse and suspend contaminants, allowing them to be carried away during oil changes.
  • Anti-Wear Agents – These additives form a protective film on metal surfaces, reducing friction and minimizing wear on engine components.
  • Viscosity Index Improvers – These additives help stabilize the viscosity of the oil over a range of temperatures. This ensures that the oil maintains its effectiveness in lubricating the engine under different operating conditions.
  • Antioxidants – These additives help prevent the oil from oxidizing and breaking down, extending the oil’s life and maintaining its properties over time.
  • Corrosion Inhibitors – These additives protect engine components from corrosion by forming a protective layer on metal surfaces.
  • Foam Inhibitors – These additives help prevent the formation of foam, ensuring efficient lubrication and preventing air entrainment in the oil.
  • Pour Point Depressants – These additives improve the low-temperature flow characteristics of the oil, preventing it from thickening in cold conditions.
  • Friction Modifiers – These additives reduce friction between moving parts, improving fuel efficiency.

Why your car needs motor oil additives

With everything we do and have in our world today, we can look back over time and see how it’s a little better than in the past. We learn. We grow. And we make things better. 

Motor oil has had that progression, too. 

Go back to the very first cars and motor oil was a base ingredient with little in it. Over time, we’ve learned to add things that make it better – better for your car, better for the environment, better for efficiency. 

Today’s motor oil additives are essential team players dedicated to keeping your car’s engine in top shape. These additives each contribute unique benefits. 

Take the detergent and dispersant combo, for instance. They actively prevent the accumulation of deposits and sludge, maintaining the engine’s cleanliness. What was once difficult or even impossible, today is handled through additives within the motor oil itself. 

Then there’s the anti-wear agent, a vital component forming a protective layer on metal surfaces, minimizing friction and preventing premature wear on critical engine parts. That’s just one reason the average age of a car on the road is creeping upwards every year. 

Yes, additives are a good thing. Your car’s engine can’t survive without motor oil. But increasingly, it can’t function well over time without motor oil additives. 

While you might not have a deep understanding of motor oil and its job, hopefully, this provides you with a little more information about its importance. 

Changing motor oil regularly is essential to the health of your vehicle. 

We can help you with that. 

It’s the best way to ensure a longer, healthier life for your engine.

How Do You Know You’re Choosing the Right Oil Change Service?

December 7, 2023 by Denver Express Car Care

Changing your car’s oil is a foundational part of routine maintenance. Oil protects your engine from wear and tear by minimizing friction as you drive. Over time, oil collects dirt and grime and becomes too dirty to lubricate an engine’s various parts. Heat builds up. Parts wear down. And if not corrected, can lead to total engine failure. 

But there’s an easy way to prevent all that: relying on an oil change service to do the job correctly the first time. Many oil change service shops design their oil changes to be as simple as possible – drop off your car and pick it up a short while later. Keep in mind that not all oil changes are created equal. 

Some shops prefer the in-and-out method. They provide based services like replacing the oil and filters as needed. 

Other shops use this as an opportunity to look at other parts that may be impacting your drive. This can alert you to potential problems before they escalate. 

Of course, if you want a full service oil change, it’s important to go with a service you can trust. Will they provide you with a realistic look at how well your car is operating? Or are they just trying to grow their profits? 

How Do You Know You’re Choosing the Right Oil Change Service?

What to look for in a full service oil change

Many auto repair shops advertise complimentary services with an oil change. For you, it’s a good place to start when trying to find a shop you can rely on for bigger jobs in the future. 

Yes, a competitive price is important. But you should look beyond that to the services they provide. There can be a vast difference between shops; they may charge you more after your car is in and being serviced. 

You should also pay attention to the technicians. Do they hire experts? Are staff members friendly and approachable? Do they take the time to explain the services being performed on your car? Or are they more get-you-in-and-get-you out? 

Do they leave an impression and make you want to do business there again? 

Full service provides an array of services

Many oil change services provide oil and filters. They consider the rest of the car someone else’s responsibility. 

Full service oil changes provide more complimentary services. Such as:

  • Draining and refilling with motor oil
  • New oil filter
  • Lubrication if needed
  • Inspect and top off all fluids, including transmission fluid, antifreeze, windshield washer fluid, battery water, and differential fluid
  • Tire air-pressure check
  • Engine light check

If there’s a problem, the technician will alert you to the fact, provide options, and ensure your car is safe and ready to drive once again. 

Why regular maintenance is essential to your car’s longevity

Your car may seem like it’s always ready for the next drive … until it isn’t. Just like us humans need regular check-ups to stay in tip-top shape, your four-wheeled friend needs some love, too.

Regular maintenance keeps everything running smoothly, prevents minor issues from turning into big, wallet-draining disasters, and ensures you’re not stranded on the roadside with a smoking engine.

Think about it as an investment in your car’s longevity and your peace of mind. Oil changes, tire rotations, brake checks – they may seem small, but they add up to a reliable and efficient ride. 

Plus, staying on top of maintenance can actually save you money in the long run by nipping potential problems in the bud before they snowball into major repairs. Saving you money and ensuring many more miles of smooth cruising. 

What is an oil and filter change?

An oil and filter change is like a spa day for your car’s engine. Imagine your car’s engine is the heart of the operation, and oil is its lifeblood. Over time, as you rev up and roll on down the road, that oil gets dirty and loses its effectiveness. That’s where the oil change is necessary.

During an oil change, the old, worn-out oil is drained from the engine, making room for a fresh batch. And it’s not just about the oil – the oil filter gets swapped out, too. The oil filter is designed to keep out dirt and debris that could cause trouble. As it does its job, it clogs, so replacing it is key to maintaining a healthy engine.

This tag team of fresh oil and a new filter ensures your engine stays lubricated and cool, running like a well-oiled machine – literally! It’s a relatively quick and straightforward procedure, but oh, does it make a difference in keeping your car’s engine humming happily along. It truly is one of the easiest ways to keep your car running. 

How often should oil be changed?

If you do any searching, you’ll discover this is a heavily debated question! 

The frequency of oil changes depends on a few factors, like the type of oil you use, your driving habits, and the manufacturer’s recommendations. As a general rule of thumb, many experts suggest getting an oil change every 3,000 to 5,000 miles. However, it’s always a good idea to consult your car’s manual because it holds the ultimate wisdom about your specific vehicle.

If you’re using synthetic oil, you might be able to stretch that interval a bit, as synthetic oils tend to last longer. Some modern vehicles equipped with advanced engine technology and synthetic oils can go 7,500 miles or more between changes.

If you’re a frequent road tripper, stop-and-go city driver, or you tow heavy loads, you might want to err on the side of caution and stick to the lower end of the mileage spectrum. The key is to stay mindful of your driving conditions and the type of oil your car drinks – it’s all about keeping that engine purring contentedly for miles to come!
