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.

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.

The Science of Car Batteries: When Your Car Has a Hard Time Starting in the Winter

December 18, 2023 by Denver Express Car Care

Push a button or turn a key and your car springs into life. You have full control over the radio, the heater or air conditioner, seat warmers, and to make the windows go up and down.

All of that is possible thanks to car batteries. This one little invention changed our world forever. Can you even imagine life without a car? While that might be possible in walkable cities, it’s hard to imagine in Colorado.

Why car batteries are important

A car battery is a rechargeable energy storage device that provides electrical energy to start the engine and power various electrical components in a vehicle. It plays a crucial role in the overall functioning of a car.

A car battery’s ultimate goal is to supply a burst of electrical power to the starter motor, which then cranks the engine and initiates the combustion process. Once the engine is running, the alternator takes over the task of generating electrical power, and it also charges the battery.

Without car batteries, you couldn’t:

Start the Engine – The primary function of a car battery is to provide the initial electrical energy required to start the engine. When you turn the key or push the ignition button, the battery sends a surge of power to the starter motor, enabling the engine to crank and start.
Operate Electrical Accessories – Car batteries serve as a source of electrical power when the vehicle is not running or when the electrical demand exceeds what the alternator can supply. They power essential components such as lights, radio, air conditioning, power windows, and other electrical accessories.
Have Reliable Power – Car batteries help stabilize the voltage in the electrical system. Fluctuations in voltage can cause issues with sensitive electronic components in modern vehicles. The battery acts as a buffer, helping to maintain a steady voltage level.
Backup Power – In the event of alternator failure or when the engine is not running, the battery acts as a backup power source. This ensures that critical systems, such as lights and safety features, remain operational.
Emergency Power Source – Car batteries can serve as emergency power sources for various situations. For example, they can be used to jump-start another vehicle with a dead battery, power portable devices through inverters, or provide limited power during emergencies.
Regulating Electrical System Load – The battery helps manage the electrical load on the alternator. During periods of high electrical demand, the battery assists in supplying power, reducing the strain on the alternator and extending its lifespan.
Smooth Engine Operation – A properly functioning battery contributes to the overall efficiency and smooth operation of the vehicle. It ensures that the engine starts reliably and that all electrical systems operate as intended.

Why a car battery has a hard time starting in the winter

Think about your own actions in winter. You move a little slower, stretch a little more, spend a little more time relaxing.

The Science of Car Batteries: When Your Car Has a Hard Time Starting in the Winter

Your car reacts similarly. Those cold temperatures can make everything inside your car a little more sluggish.

Reduced Battery Performance – Cold temperatures can significantly reduce a car battery’s ability to deliver power. Chemical reactions in the battery that generate electricity slow down in cold weather. As a result, the battery may not provide enough power to crank the engine.
Increased Engine Oil Viscosity – Cold temperatures cause engine oil to become thicker and more viscous. Thick oil is harder for the engine to pump, which can make it more difficult to turn over, especially during startup.
Stiffening of Lubricants and Fluids – Other fluids in the vehicle, such as transmission fluid and brake fluid, can also become thicker in cold weather. This can affect the overall efficiency of various components in the vehicle.
Cold Air Intake – Cold air is denser than warm air, and a cold air intake system can lead to a richer air-fuel mixture. While this is generally beneficial for engine performance, frigid temperatures may cause difficulties in starting.
Fuel Combustion Challenges – Cold temperatures can make the fuel-air mixture more difficult to ignite. Additionally, fuel may not vaporize as effectively in cold weather, affecting combustion efficiency.
Frozen Fuel Lines – In icy conditions, moisture in the fuel system can freeze, leading to blockages in fuel lines. This can impede the flow of fuel to the engine and cause starting issues.
Challenges with Spark Plugs – Cold temperatures can make it more difficult for the spark plugs to ignite the air-fuel mixture. Spark plugs need to generate sufficient heat to initiate combustion, and extreme cold can hinder this process.

Battery tips to keep your car running smoothly all winter long

You can’t avoid winter. (Unless you move.) And your car will react differently as you carry on with your daily activities throughout the cold weather months.

But that doesn’t mean there aren’t things you can do.

Check the Battery – Regularly inspect the battery for signs of corrosion or loose connections. Clean any corrosion with a mixture of baking soda and water.
Ensure that the battery terminals are tight and secure.
Perform a Battery Test – Use a battery tester to check the state of charge and overall health of the battery. Many automotive stores offer free battery testing services. Or you can stop by and we’d be happy to perform an inspection.
Keep the Battery Charged – Cold temperatures can reduce a battery’s efficiency. If possible, park your car in a garage to provide some insulation from the cold.
Consider using a battery maintainer or trickle charger to keep the battery charged when the vehicle is not in use for extended periods.
Use a Battery Blanket or Heater – Install a battery blanket or heater to keep the battery warm during extremely cold weather. This can improve its performance and extend its lifespan.
Choose the Right Engine Oil – Use engine oil with the correct viscosity rating for winter. Thinner oil flows more easily in cold temperatures and reduces the strain on the battery during startup.
Turn Off Accessories Before Shutting Off the Engine – Before turning off the engine, make sure to turn off all accessories such as lights, radio, and heaters. This reduces the load on the battery during the next startup.
Limit Short Trips – Cold starts require more energy from the battery. Limiting short trips can help the alternator recharge the battery fully, ensuring it stays in good condition.
Check for Parasitic Drains – Ensure there are no unnecessary electrical loads on the battery when the car is turned off. Check for and fix any parasitic drains that could be draining the battery.
Emergency Preparedness – Keep jumper cables or a portable jump starter in your vehicle. In case of a dead battery, these tools can help you or someone else jump-start the vehicle.
Consider a Battery with Cold-Cranking Amps – When replacing your battery, choose one with a higher CCA rating, which indicates its ability to start in cold temperatures.

Take care of your car batteries this winter

Nothing is worse than heading outside on a cold winter morning and finding your car battery dead. Your car won’t crank over. It doesn’t make a sound.

It doesn’t have to happen. There are warning signs. With a little regular maintenance and TLC, your car battery will be there when you need it most.

We can help.

Stopping Power 101: How Your Car’s Brakes Actually Work

December 14, 2023 by Denver Express Car Care

Did you love Saturday morning cartoons when you were young? The Flintstones is a classic. What kid doesn’t love the idea of having a dinosaur for a pet? Or using your feet to start and stop a car?

The concept seems a bit childish when you age and understand just how fast a car goes. Starting a car – maybe. If you’ve ever had to push a car to start it, you realize power comes from forward motion.

But stopping – that’s altogether different. You need more than feet to stop a car.

Driving here in Colorado, car brakes are an important part of our daily commute. Whether you sail in and out of the pickup line for your kids, or fly down the highway for a day of skiing with friends, life would be tricky (and treacherous) without brakes.

But have you ever stopped to think about how they get their stopping power? What makes car brakes work?

Let’s find out.

Where car brakes started

The invention and development of car brakes can be attributed to several individuals over time. The early automobiles did not have effective braking systems, and the earliest forms of braking were rudimentary compared to modern standards.

One notable early advancement in automotive brakes was the introduction of mechanical brakes. In the late 19th century, various inventors and automobile pioneers began experimenting with braking systems. One such example is the application of mechanical brakes on the horseless carriage built by Karl Benz, the inventor of the first practical motorcar, in the late 1880s.

Stopping Power 101: How Your Car's Brakes Actually Work

However, the early braking systems were often primitive and unreliable. The transition from mechanical brakes to hydraulic brakes, which significantly improved braking efficiency and reliability, occurred over the early decades of the 20th century.

In 1918, Malcolm Loughead (later changed to Lockheed) introduced hydraulic brakes on the Duesenberg automobile. This marked a significant advancement in braking technology, providing more reliable and responsive braking compared to mechanical systems.

As the automotive industry continued to evolve, hydraulic brake systems became more widespread. The development of power-assisted brakes, such as vacuum-assisted and later hydraulic-assisted systems, further improved braking performance and control.

How today’s modern car brakes work

Modern car brake systems primarily rely on hydraulic mechanisms and friction materials to achieve effective deceleration and stopping. The prevalent disc brake system in contemporary vehicles comprises essential components such as brake discs or rotors, brake calipers, brake pads, and a hydraulic system.

When the driver presses the brake pedal, a hydraulic process is initiated. This begins with the master cylinder, which contains brake fluid and pressurizes it upon pedal depression. The pressurized brake fluid is then directed through brake lines to the brake calipers at each wheel.

In disc brake setups, the calipers house pistons that, when activated by the brake fluid, squeeze the brake pads against the rotating brake discs. These discs, attached to the wheel hub, generate friction when in contact with the brake pads, converting kinetic energy into heat and ultimately slowing down the vehicle.

Brake pads are positioned on each side of the brake discs within the calipers. They play a crucial role in this process by providing the necessary friction. The heat produced is managed through ventilation slots in the discs and other cooling features to prevent brake fade.

Additionally, modern cars often feature advanced systems such as Anti-lock Braking System (ABS), Electronic Brake-force Distribution (EBD), and Brake Assist to enhance safety and control during braking maneuvers. ABS prevents wheel lock-up by modulating brake pressure, while EBD optimizes the distribution of braking force among individual wheels. Brake Assist recognizes emergency braking situations and supplements braking force if the driver doesn’t apply sufficient pressure.

Overall, modern brake systems are designed for efficiency, reliability, and safety, incorporating advanced technologies to deliver optimal performance.

Brakes work only as well as the driver behind them

According to the Office of Motor Vehicle Management, 98 percent of all car accidents are due to human error.

Want to be a better driver? Until autonomous vehicles become the norm, the best way is to sharpen your driving practices. This is where you should start.

Anticipate Stops – Be aware of traffic conditions, signals, and road signs well in advance. Anticipating stops allows you to brake gradually and smoothly.
Maintain a Safe Following Distance – Keep a safe distance from the vehicle in front of you. This provides you with more reaction time and space to stop safely.
Gradual Braking – Avoid abrupt or sudden braking, as it can lead to skidding or collisions. Gradually apply pressure to the brake pedal to slow down smoothly.
Avoid Overusing Brakes on Downgrades – On downhill slopes, use engine braking (shifting to a lower gear) where appropriate to reduce the load on the brakes. This helps prevent brake fade and overheating.
Check Brake System Regularly – Ensure that your vehicle’s braking system is well-maintained. Regularly check brake fluid levels, brake pads, and discs. Address any issues promptly.
Adapt to Road Conditions – Adjust your stopping distance based on road conditions. Wet or slippery surfaces may require increased stopping distances, so be mindful of the weather and road conditions.
Avoid Tailgating – Maintain a safe following distance to allow for unexpected stops by the vehicle in front of you. Tailgating reduces your reaction time and increases the risk of rear-end collisions.
Use Turn Signals – Use turn signals to indicate your intention to stop or turn. This alerts drivers behind you and improves overall road safety.
Stay Alert at Intersections – Be particularly vigilant at intersections. Look for pedestrians, cyclists, and other vehicles before proceeding or stopping.
Practice Defensive Driving – Stay aware of your surroundings, anticipate the actions of other drivers, and be prepared to react to unexpected situations.

And above all, check your brake system regularly. You can do this by paying attention to the way your brakes perform. Notice a difference in sound, touch, or odor? It’s time to bring it in for inspection. Have a dashboard light illuminated? Don’t ignore it; it’s a sign something is wrong.

If you have a question, we’re here to help.

Diagnosing and Preventing Engine Overheating

November 21, 2023 by Denver Express Car Care

There are many advantages to buying a new car. When everything is new, the chances of a problem occurring while on the road are minimal.

Of course, new cars face whatever is on your daily commute. Weather. Potholes. Aggressive drivers. Climbing mountains and zipping around town. Eventually they wear down.

You start to notice it in the little things.

When all systems are running smoothly, it’s smooth sailing. But sometimes, the unexpected occurs: your engine overheats.

To an auto enthusiast or an experienced mechanic, the reasons might be clear, yet for many, the cause and solution can be an elusive mystery.

What can it be? And more importantly, what can you do?

What Happens When an Engine Overheats

Have you ever experienced an engine overheating before?

Engine overheating is when the engine temperature escalates beyond the normal range, compromising the functionality and safety of the vehicle. The overheating can result in warped parts, head gasket failure, or even a cracked engine block, all of which are as daunting and expensive as they sound.

In a nutshell, an overheating engine is not just a minor hiccup, but a critical concern that demands immediate attention. Acting quickly is your best course of action.

Causes of Engine Overheating, Explored

Why would an engine overheat? Understanding the why before the how is pivotal. The causes of engine overheating range from easily fixable to technically complex issues. Let’s explore them:

Diagnosing and Preventing Engine Overheating

Low Coolant

A fundamental cause for overheating is low coolant levels, depriving the engine of the essential medium that absorbs and dispels heat through the radiator. Coolant levels can drop due to leaks, evaporation, or simply over time with usage. Regularly checking and maintaining coolant levels are paramount to ensuring a consistent temperature within the engine.

Coolant Leak

Leaks can occur in several locations within the cooling system: the radiator, hoses, water pump, head gasket, or thermostat housing. Traces of dried coolant, usually bright green, pink, or orange, may hint towards a leak source. Leaks contribute to decreased coolant levels, diminishing the system’s ability to manage engine temperature.

Low Coolant Pressure

Optimal coolant pressure ensures the fluid efficiently travels through the cooling system, absorbing, and discharging heat. The pressure cap maintains this pressure, and its failure or a leak within the system can jeopardize the pressure stability, impairing cooling capabilities.

Low Oil

Engine oil wears many hats, one of which includes absorbing excess heat from the engine. When oil levels plummet, its ability to act as a heat absorber is compromised, placing additional heat management demands on the coolant and, in tandem, accelerating wear on moving parts due to insufficient lubrication.

Thermostat Problems

Acting as the cooling system’s regulator, the thermostat controls the coolant flow between the engine and the radiator. A malfunctioning thermostat may fail to open, hindering coolant flow and causing the engine to overheat. Its consistent performance is crucial for maintaining an equilibrium in engine temperature.

Broken Fan

The fan assists in maintaining a steady temperature in the radiator and, subsequently, the engine. A malfunctioning fan, due to a faulty motor, damaged fan belt, or debris, compromises the system’s cooling efficacy, allowing heat to build up within the engine.

Damaged Radiator

The radiator, tasked with dissipating the heat from the coolant, is a pivotal component in preventing overheating. Physical damage, internal corrosion, or blockages can impair its functionality, diminishing its ability to expel heat and maintain a balanced engine temperature.

Broken Water Pump

Often dubbed the heart of the cooling system, the water pump circulates coolant through the engine and radiator. Its failure, through a leak, broken impeller, or shaft issues, disrupts coolant flow, jeopardizing the entire cooling process.

How to Fix an Overheating Engine: Diving Deeper

That’s a lot that can go wrong! But don’t worry; maintenance is key to prevention. That’s why it’s important to find a trustworthy auto repair shop early in your ownership, and partner with them to ensure your car runs smoothly.

If by chance you do face an overheating engine, let’s dive into some troubleshooting and fixes:

Check Fluid Levels

Begin with the basics: inspect the coolant and oil levels. Initial checks should always encompass evaluating the coolant and oil levels, ensuring they adhere to manufacturer guidelines. Additionally, observe the color and consistency of the fluids to rule out contamination.

Pressurize the System to Look for Leaks

Utilizing a pressure tester can be invaluable in identifying leaks within the cooling system. Pressurizing forces coolant out through leaks, providing a tangible indication of the problematic area. (You don’t have to buy one if you don’t want to. That’s why partnering with a mechanic has its advantages.)

Check for Damage

A visual inspection can unveil apparent issues, such as leaks, damaged hoses, or corroded surfaces. Regular checks can preemptively identify problems before they morph into larger complications.

Bring it in for Inspection

Perhaps the most foolproof way to diagnose and remedy an overheating engine is to bring your vehicle to a professional.

When Was The Last Time You Changed Your Motor Oil?

November 7, 2023 by Denver Express Car Care

Motor oil is one of the necessary common maintenance items of owning a car.

You wouldn’t imagine your car operating without regularly pulling into the gas station. The same applies to motor oil.

It’s something every driver understands on some level.

But how often should you change your motor oil? That question is heavily debated online.

Should you schedule it every 3,000 miles? Can you wait 5,000? New advice states you can even wait 10,000 miles or more with some cars. Is that true?

Cars today are staying in service longer than ever before … 12 years on average. But a car won’t stay running and be a reliable asset in your life if you don’t care for it.

Yes, cars are more sophisticated than ever before. Yet no matter how much technology influences how a car operates, if it’s an internal combustion engine, motor oil will always be the lifeblood.

What motor oil does for a car

Motor oil serves a vital role in keeping your car’s engine running smoothly and efficiently. One of its main jobs is to reduce friction between the many moving parts inside the engine, like pistons and crankshafts, helping to prevent premature wear and damage. As the engine runs, it generates a lot of heat. Motor oil helps dissipate this heat, keeping the engine at a safe operating temperature.

But that’s not all; motor oil also acts as a cleaner. Over time, dirt and debris can build up in the engine, potentially causing harm. Motor oil contains special additives that trap and suspend these contaminants, pushing them through the oil filter to remove them. This helps keep the engine clean and running smoothly.

Motor oil creates a seal in the engine, which is crucial for maintaining compression in the cylinders and ensuring efficient combustion. It also protects engine components from corrosion, reducing the risk of rust and deterioration. Plus, it plays a role in reducing engine noise and vibrations, contributing to a quieter and more comfortable ride.

When Was The Last Time You Changed Your Motor Oil?

Did you know your motor oil did all that? Now imagine your engine if the motor oil isn’t doing its job.

What if you don’t change the motor oil?

We all know motor oil is important to keep a car operational. Still, it sometimes sinks to the bottom of your to-do list. You keep pushing it aside with more important things to do.

Here’s why you shouldn’t.

Over time, that oil gets dirty and gunky, filled with all sorts of debris and contaminants from your engine. This contaminated oil can’t do its job properly to keep things running smoothly. Without adequate lubrication, your engine’s moving parts start to rub against each other, causing wear and tear. That means your engine might not last as long as it should, and you could be facing some hefty repair bills.

Your car’s performance takes a hit, too. You might notice it feels weaker, slower to respond, and drinks more gas. That’s because the engine has to work harder without sufficient oil. Plus, there’s the risk of your engine overheating, which can lead to serious problems like warped parts and engine damage.

This can all impact your wallet. Poor engine performance and efficiency mean you’re burning more fuel for the same distance traveled, costing you extra at the pump. On top of that, a poorly maintained engine can throw out more harmful emissions, which are not great for the environment and may even make your car fail emissions tests.

Worst-case scenario? Your engine might give up on you altogether. Yep, that’s a pricey situation to fix. So, don’t skip those regular oil changes. It’s a simple and cost-effective way to keep your car running smoothly, save money in the long run, and avoid a lot of headaches.

Convinced? Here’s how often you should change your motor oil

Changing your motor oil is based on mileage. It’s also based on timing. Here’s why.

Let’s say you work from home, and your car sits in the garage most days. You take it out occasionally – a trip to the grocery store 3 miles away, a night out at a restaurant 5 miles from your house.

To hit 3,000 miles at that rate may take you nine months or more. In this circumstance, it’s better to err on the side of caution and replace it at least twice per year. Short trips aren’t enough to heat your engine rough to boil off condensation accumulating within the system. This can cause motor oil to break down faster.

Let’s talk about the age of your car. If you’ve purchased it in the last few months, start by looking at the owner’s manual for guidance. Many manufacturers suggest 5,000, 7,500, or even 10,000 miles or more between motor oil changes. Again, you should take your driving style and habits into account.

A new car driven regularly at fairly steady speeds creates the perfect scenario for going a little longer between oil changes. An older car that is driven erratically in stop-and-go traffic provides a reason to change it more frequently to ensure the motor oil remains in good working condition.

What about synthetic motor oil?

When your car was designed, it was with a specific motor oil in mind. You’ll find the weight of motor oil needed printed on the cap where you add the oil. It’s listed in your owner’s manual, too. The manufacturer knows best; going with what’s recommended or required assures you use the right motor oil for the way your vehicle was designed. It can also save you money and avoid using motor oil that may not be best for your car’s engine.

That said, older cars may work better by upgrading motor oil. Synthetic oil is designed to be more effective at resisting breakdown and withstanding higher temperatures. It’s also designed to last longer, meaning 10,000 miles or more may be possible.

Yes, there isn’t always a clear road to deciding what motor oil is best. That’s where finding a trusted auto mechanic can help you navigate oil changes more effectively.

If a service only offers oil changes, they are more likely to push everything they can to up the sale – more expensive motor oil, upgraded filters, and more frequent servicing.

When you work with a mechanic there to keep your car running smoothly, you’ll get honest advice about what best suits your vehicle and how you drive.

If you haven’t worked with us before, you’re in for a surprise. We’re a family-owned and operated business that still thrives on offering sound advice.

Is that what you need to keep your car running smoothly?

What’s an Exhaust Resonator and What Does It Do?

October 24, 2023 by Denver Express Car Care

What’s the most sophisticated system on your vehicle? You might be tempted to say the braking system, or possibly the transmission, but we’d move another system to the top of the list: The exhaust system.

The exhaust system is a complicated process that uses the manifold, flex pipe, catalytic converter, isolators, mufflers, and resonators to improve performance and safety of the vehicle.

Not sure what a resonator does or why your car needs one?

How the Exhaust System Works

Your car’s engine generates power by burning fuel and air in the combustion chamber. This process produces exhaust gasses that contain harmful elements like carbon monoxide, nitrogen oxides, and unburned hydrocarbons.

The primary purpose of the exhaust system is to safely and efficiently guide these noxious gasses away from the engine and out into the environment. It’s a critical aspect of your vehicle’s operation, as a properly functioning exhaust system helps maintain engine performance, fuel efficiency, and reduces harmful emissions.

The exhaust system consists of several key components, including:

Exhaust Manifold – This is the first stop for the exhaust gasses, collecting them from each cylinder and channeling them into a single pipe.

Catalytic Converter – Located downstream from the manifold, the catalytic converter reduces harmful emissions by converting pollutants into less toxic compounds.

What’s an Exhaust Resonator and What Does It Do?

Muffler – The muffler’s job is to dampen the noise created by the high-pressure exhaust gasses as they exit the engine.

Resonator – The resonator plays a significant role in fine-tuning the exhaust sound and reducing specific frequencies.

Tailpipe – The tailpipe directs the treated exhaust gasses out of the vehicle, away from the passenger cabin.

Now, let’s zero in on the exhaust resonator and understand its role in this symphony of mechanical components.

What a Resonator Does

Imagine your car’s exhaust system as a musical instrument, and each component plays a specific note or tone. The exhaust resonator is like the equalizer in this musical analogy, responsible for adjusting and harmonizing the exhaust note.

Resonators are designed to address a specific issue in the exhaust system: the presence of unwanted sound frequencies, often referred to as “drone” or “boom.” When your car’s engine produces exhaust gasses, it does so at various frequencies and amplitudes. Some of these frequencies can create an unpleasant or loud exhaust note that resonates inside the cabin, causing the driver and passengers discomfort.

The resonator’s magic lies in its ability to cancel out these undesirable sound frequencies by creating sound waves of equal amplitude but opposite phase. In simple terms, it muffles the unwanted noise by producing an opposite sound, effectively reducing the overall volume and making your car’s exhaust note more pleasant.

So, if you’ve ever admired a car’s deep, throaty growl or smooth purr, you have the resonator, among other components, to thank for that melodic experience.

What Is the Difference Between a Resonator and a Muffler?

While both components play a part in controlling the exhaust sound, they serve different purposes and achieve distinct results.

A resonator targets specific frequencies in the exhaust note and cancels them out. Resonators are more focused on fine-tuning the sound and eliminating drone or unwanted tones.

Mufflers have a broader role in the exhaust system. They reduce overall noise levels by using sound-deadening materials and baffles to muffle the sound produced by the exhaust gasses. Mufflers are responsible for the overall reduction in exhaust noise and play a crucial role in maintaining a comfortable noise level for both the driver and passengers.

In essence, the resonator is like a precision tool for fine-tuning your car’s exhaust note, while the muffler is the general sound dampener that reduces overall noise levels.

Can a Resonator Go Bad?

Like any other car component, a resonator can go bad over time. While it’s not as prone to wear and tear as some other parts, it’s not immune to issues. But problems can occur.

Corrosion – Resonators are exposed to high temperatures and moisture, making them susceptible to corrosion over time. Rust can eat away at the resonator’s body, weakening its structural integrity.

While it might look like it can take on the world, new cars need a little TLC while they settle in. With thousands of parts coming together for the first time, it’s a good idea to give them a break and treat them with kindness.

The thrill of getting behind the wheel of a brand-new vehicle is incomparable. But as with any new relationship, starting off on the right foot is essential. When it comes to your new car, the initial break-in period is crucial for ensuring its longevity and performance down the road.

This is where we suggest you begin.

Get to Know Your New Car

Congratulations on your new car! It’s not just a mode of transportation; it’s a new adventure waiting to unfold. The first step to building a solid relationship with your car is getting to know it inside and out.

Bought a New Car? Car Engine Break-In Best Practices

Spend some quality time familiarizing yourself with the various components and features. Adjust the seats and mirrors, explore the infotainment system, and get comfortable with the control layout.

And don’t overlook the owner’s manual. It might not be the most thrilling read, but it’s a goldmine of information about your car’s maintenance requirements, recommended fluids, and even troubleshooting tips. It’s like the user manual for a video game – it holds all the secrets to mastering the game of car ownership.

Has it been a while since you’ve driven a new car? You might be pleasantly surprised at the number of advanced driver assistance systems in modern vehicles. These technologies, such as adaptive cruise control and lane-keeping assist, can significantly enhance your driving experience. But they can take some time to understand how these features work.

Most manufacturers provide tutorials online, and experimenting in a safe environment can help you feel more confident using them on the road. There’s nothing wrong with staying in your quiet local community while you experiment with each system.

Build Your Toolbox

Just like you wouldn’t embark on a camping trip without the right gear, you shouldn’t hit the road in your new car without the essential tools. You might not be heading into the wilderness, but unexpected situations can arise, and having the right tools on hand can save the day.

An ice scraper is a must-have here in Colorado’s colder climate. You never know what today’s weather will bring, and it’s a good idea to always be prepared. It’s your ticket to a clear windshield on frosty mornings.

Jumper cables can be a lifesaver when your battery decides to play hard to get. Your car may be new now, but creating your kit now will save you down the road.

Engine Break-In: Gentle Start for Longevity

You wouldn’t sprint a marathon right out of the gate, would you? The same principle applies to breaking in your new car’s engine. The goal of the break-in period is to allow the various components to settle into their optimal positions, ensuring smooth operation for years to come.

During the first 1500 miles or so, avoid pushing the engine to high RPMs. Once you reach this mark, you can gradually vary your speed and RPMs, knowing your car’s engine is in good shape. This helps the engine’s moving parts wear in evenly. While modern engines are designed to be durable, this cautious approach can significantly contribute to your engine’s longevity.

Additionally, don’t be in a rush to rev up a cold engine. Give it a minute to warm up before demanding too much from it. Cold starts can cause extra wear and tear on the engine, impacting its performance over time.

Gentle on the Pedals, Gentle on the Car

The break-in period isn’t just about being kind to the engine. It’s also a good time to be gentle with the other components of your car. This includes the tires, brakes, and shocks. Avoid sudden, aggressive stops or sharp turns that could stress these components.

When you do need to brake, try using a light touch. This not only extends the life of your brake pads but also contributes to a smoother overall driving experience.

And remember, your tires need a little TLC, too. Keep them properly inflated and rotate them regularly to ensure even wear.

Partnering with a Reputable Maintenance Shop

Maintaining a healthy relationship with your car doesn’t end after the break-in period. Just like any relationship, it requires ongoing effort and attention.

Finding a trustworthy car maintenance shop can be a game-changer. Look for one with a solid reputation and experienced technicians who know the ins and outs of your vehicle.

Stick to a regular maintenance schedule recommended in your owner’s manual. This typically includes oil changes, fluid checks, and filter replacements.

Regular maintenance keeps your car running smoothly and helps catch potential issues before they escalate into costly problems. And if you have a relationship with a mechanic you can trust, you’ll be more likely to trust their advice and be more apt to bring your vehicle in at the first sign of a minor problem.

Tracking for Success

As you dive into the world of car ownership, consider keeping track of your car’s maintenance history. A simple spreadsheet or even a dedicated app can help you stay on top of oil changes, tire rotations, and other essential maintenance tasks.

This proactive approach can lead to better care for your car, ultimately leading to a longer and healthier life for your vehicle.

And if you do ever sell your car, this can be a valuable tool to make your car more valuable.

What’s your car engine break-in practice?

Whether this is your first new vehicle or one of many, the journey of car ownership begins with a gentle touch.

Taking the time to get to know your new car, learning its features, and adhering to best practices during the break-in period can set the stage for a rewarding and long-lasting relationship. Remember, your new car isn’t just a machine; it’s a partner in your daily adventures.

Why Ignoring Car Alignment Issues Can Be Costly

September 18, 2023 by Denver Express Car Care

Remember the last time you hit a pothole, and it rattled your vehicle? You saw it too late to avoid it, but it shook your car hard enough for you to think about long after you drove away.

Wheels can become misaligned easily as you drive. While they’re designed to be durable, you never know what will cause a problem somewhere within the system. And that can set off a host of chain reactions.

Why Car Alignment is Important for Your Vehicle

What exactly is car alignment, and why does it matter? Car alignment refers to the adjustment of the angles of your vehicle’s wheels so that they are parallel to each other and perpendicular to the road. Proper alignment ensures your car drives straight, handles well, and maximizes tire life.

While we’d like to think proper alignment holds for thousands of miles, the reality is it can be altered by driving away from the repair shop. We can’t predict what will be in the road, or how it will impact how our car drives.

When car alignment is misaligned, getting it fixed quickly can stop minor issues from becoming costly fixes.

What Happens When You Wait Too Long

Imagine driving down the road with your vehicle’s alignment out of whack. The longer you delay addressing this issue, the more consequences you’re inviting into your car’s health.

Why Ignoring Car Alignment Issues Can Be Costly

Uneven Tire Wear

One of the most visible signs of alignment issues is uneven tire wear. Misaligned wheels put uneven pressure on your tires, causing some parts of the tread to wear down faster than others. Uneven tire wear not only shortens your tire’s lifespan but also compromises traction, leading to decreased safety on the road.

Steering Problems

Ignoring alignment can throw your steering out of balance. If you find yourself constantly adjusting the steering wheel to keep the car moving straight, your alignment might be off.

You might also notice it in the way your steering wheel sits. Glance down at the emblem in the center of the steering wheel while driving straight. If it tips either to the left or right, it’s a sign your vehicle needs a wheel alignment.

Poor Fuel Economy

Here’s a sneaky way misalignment can hit you in the wallet: poor fuel economy. When your wheels aren’t aligned correctly, your car has to work harder to move forward. This increased resistance can lead to decreased gas mileage, meaning more trips to the pump and more money out of your pocket.

How to Tell If You’re Experiencing Car Alignment Issues

Wheel alignment is important. It’s not difficult to understand why. Yet knowing it and knowing when it should be fixed are two different things. How do you identify those pesky alignment issues before they become bigger problems?

Vehicle Pulls to One Side

Does your car seem determined to veer to the left or right, even when driving on a straight road? If so, it’s a clear sign that your wheels might be misaligned.

Uneven Steering Wheel

Take a look at your steering wheel while driving on a level road. If it’s tilted to one side even though you’re driving straight, it’s time to consider an alignment check.

Loose Steering

Is your steering wheel feeling a bit too loose and wobbly? Misaligned wheels can lead to a lack of responsiveness in your steering, making your vehicle harder to control.

Vibrating Steering Wheel

If you feel vibrations through the steering wheel, especially at higher speeds, it could be an indication of alignment issues or other problems with your tires or suspension.

Uneven Tire Wear

Inspect your tires regularly for signs of uneven wear. If you notice that the tread is wearing down more on one side of the tire than the other, it’s time to schedule an alignment check.

Squealing Tires

Misaligned wheels can cause your tires to squeal as they make contact with the road. This not only sounds unpleasant but also points to a need for alignment correction.

Understanding Alignment

Alignment isn’t just a one-size-fits-all fix. It involves adjusting three key angles:

Camber

This angle measures the tilt of your wheels when viewed from the front. Too much positive or negative camber can lead to uneven tire wear and handling issues.

Toe

Toe refers to the angle at which your tires point in or out when viewed from above. Incorrect toe settings can cause tire wear, as well as instability in steering.

Caster

Caster is the angle of your steering axis when viewed from the side. It affects steering stability and the return of your steering wheel to its center position after turning.

Bringing your vehicle in will allow one of our mechanics to assess your car and determine the best way to fix it and get you on the road once again.

Why You Should Fix Car Alignment Issues Right Away

Think of your car’s alignment like your own health. Ignoring a minor ache or pain might lead to a more serious problem down the road. Similarly, not addressing alignment issues promptly can result in bigger and more expensive repairs.

Fixing alignment issues sooner rather than later:

Saves Money

Regular alignment checks and adjustments are a relatively inexpensive preventive measure compared to the potential costs of tire replacement, suspension repairs, and more.

Improves Safety

Proper alignment ensures your tires have maximum contact with the road, enhancing your vehicle’s stability and grip, especially during emergency maneuvers.

Preserves Tire Life

Correct alignment spreads the wear on your tires evenly, extending their lifespan and helping you avoid the cost of premature tire replacements.

Enhances Fuel Efficiency

Aligned wheels reduce rolling resistance, contributing to better fuel economy and putting more money back in your wallet over the long run.

It’s time to fix your car’s alignment

Taking care of your car’s alignment might not be the most exciting aspect of car ownership, but it’s undoubtedly a vital one. Ignoring alignment issues can lead to a host of problems – all of which can dent your bank account. So, watch for signs of misalignment, and don’t hesitate to bring your vehicle in for a check if something feels off. Remember, a little preventive care today can save you a lot of money and headaches in the future.

September 7, 2023 by Denver Express Car Care

Heading out onto the open road is always an exciting experience. You’re dreaming about your final destination. You have work chores in mind, ticking things off to complete during your busy day ahead.

What you’re not prepared for is car trouble. If you’re having car engine performance issues, your entire day may be spent dealing with the problem.

Owning a car comes with its fair share of joys and challenges, and one of the most frustrating challenges is when your car’s engine isn’t performing as it should. But fear not! We can help you troubleshoot the most common engine performance issues.

The Engine Won’t Start

Picture this: you’re ready to head out for an important meeting or a long-awaited road trip, and your car refuses to start. Don’t panic! Start by checking the basics.

Are your lights, radio, and other electrical components working? If they are, then your battery is likely not the issue. If they’re not working, a dead battery might be the culprit, and jump-starting your car could do the trick.

If the battery isn’t the issue, move on to checking the starter and the ignition switch. A clicking noise when you turn the key might indicate a faulty starter. If you hear nothing at all, the ignition switch could be to blame.

It’s always a good idea to have a set of jumper cables, a spare key, and the number of a reliable tow service in your back pocket – just in case.

The Art of Troubleshooting Car Engine Performance Issues

The Check Engine Light Turns On

Ah, the infamous check engine light – the little yellow indicator that can send shivers down any driver’s spine. First, take a deep breath. The check engine light can be triggered by a multitude of issues, ranging from something minor to more serious problems.

The first step is to retrieve the trouble codes from your car’s onboard diagnostic (OBD) system. You can do this by using an OBD-II scanner, which is available at auto parts stores or online.

Once you have the trouble codes, you can start narrowing down the issue. Keep in mind that the code doesn’t always point directly to the faulty component; it’s more like a clue in a detective story. You might need to do some further investigation or seek professional help if the problem seems beyond your expertise.

The Engine is Overheating

Seeing your temperature gauge spike into the red zone can be nerve-wracking, but don’t hit the panic button just yet. An overheating engine can be caused by various factors, such as a faulty thermostat, a malfunctioning radiator fan, or a coolant leak.

Quick Fix: If you notice your temperature gauge climbing, turn off your air conditioning and turn on the heat to high. This might sound counterintuitive, but it helps transfer heat away from the engine. Pull over as soon as it’s safe and let the engine cool down before opening the hood.

To prevent overheating, regularly check your coolant levels and look for any visible leaks. If you’re comfortable, you can also inspect the radiator hoses for cracks or bulges. Keep in mind that a more complex issue might require a visit to your trusted mechanic.

The Engine is Stalling

Dealing with a stalling engine can make any driver feel like they’re on a roller coaster of frustration. Stalling can occur for various reasons, such as a clogged fuel filter, a malfunctioning oxygen sensor, or even a problem with the spark plugs.

DIY Tip: Start by checking your air filter. A dirty air filter can disrupt the air-fuel mixture, leading to stalling. If your air filter looks like it’s seen better days, replacing it could potentially solve the issue.

If the problem persists, consider when the stalling occurs. Is it more likely to happen when idling, accelerating, or decelerating? This information can help you narrow down the possible causes and give your mechanic a head start in diagnosing the problem.

You Notice Steam or Smoke

Seeing steam or smoke billowing from your car’s engine can instantly make you panic. But before you jump to conclusions, let’s break it down. Smoke can be white, black, or blue, and each color might point to a different issue.

White Smoke: If your engine is emitting white smoke, it could be a sign of a coolant leak. This could mean a blown head gasket or a cracked engine block, both of which are serious problems that require immediate attention.

Black Smoke: Black smoke usually indicates the air-fuel mixture is too rich. This can be caused by a clogged air filter, a faulty fuel injector, or a malfunctioning oxygen sensor.

Blue Smoke: Blue smoke is often a sign of burning oil. This could be due to worn piston rings, valve seals, or other internal engine components.

Addressing these issues might involve replacing parts, fixing leaks, or even rebuilding parts of your engine. In any case, it’s best to consult a professional to accurately diagnose and resolve the problem.

You Hear a Funny Noise

Cars have their own language of sounds, and as a driver, it’s essential to pay attention to what your car is telling you. If you hear an unusual noise, don’t just crank up the radio to drown it out – listen closely. A clunking noise could indicate a problem with your suspension, while a squealing noise might point to worn-out brake pads.

Pro Tip: If you hear a knocking noise coming from under the hood, it could be a sign of engine trouble, such as detonation or worn-out bearings. It’s crucial to address this promptly, as engine issues can escalate quickly if left unchecked.

If you’re uncomfortable diagnosing the noise, don’t hesitate to take your car to a professional. They have the experience and tools to pinpoint the source of the noise and provide a proper solution.

Ignoring Oil Changes and Coolant Levels

Skipping oil changes and neglecting coolant levels might seem like time-saving measures, but in reality, they can lead to major engine performance issues down the road. Engine oil lubricates and cools your engine’s moving parts, while coolant prevents your engine from overheating.

Vital Reminder: Regular oil changes and checking coolant levels are simple yet crucial tasks that can extend the lifespan of your engine and prevent costly repairs.

There’s Water in the Engine

Water and engines don’t mix well, so if you suspect water has found its way into your engine, take immediate action. This can happen if you’ve driven through deep water or your engine has been exposed to heavy rain.

What to Do: If you’ve driven through water higher than the bottom of your vehicle, don’t attempt to start the engine. Have your car towed to a professional to assess the damage. Starting the engine with water in the intake system can lead to hydrolock, which can cause severe engine damage.

How’s your car engine performance?

The art of troubleshooting car engine performance issues involves a combination of observation, investigation, and, when needed, seeking professional help. While it’s tempting to become a DIY hero, remember that some problems are best left in the hands of experienced mechanics.

Regular maintenance, a keen ear for unusual sounds, and a bit of patience will go a long way in keeping your engine running smoothly and your stress levels in check. And with these tips in mind, you’ll be ready to handle it like a pro!
