Regular vs Synthetic Motor Oil – What You Should Know

by

When you own a car, regular maintenance is a part of ownership. You fill the tank up with gas because without it, your car wouldn’t go. You change out the motor oil every 3,000 miles or so because if you don’t, you’ll eventually be stranded by the side of the road.

But have you ever thought about what motor oil is? Or how it works? Or if you’re using the right type of motor oil for your vehicle?

What is regular motor oil?

If you drive a car with an internal combustion engine, it requires motor oil to operate. It’s one of the most critical components to keep the engine running well.

Inside the engine are a variety of parts that work together, create friction, and convert that to energy using a tremendous amount of heat. If the parts don’t stay lubricated and operating well, fuel consumption is diminished, the vehicle won’t operate as designed, parts will wear down and break, with engine failure not far behind.

While there is a debate about oil changing frequency, there isn’t a fight over the necessity to change it regularly. It’s better to err on the side of frequency and keep all parts lubricated and working well.

In the past, regular motor oil was the only choice. It worked well, and drivers never gave it much thought. Manufacturer’s often had several motor oil viscosities for drivers to choose from based on the type of driving they did. Viscosity determines the fluid’s resistance to flow; in a hot climate, a higher density would better serve the engine. Checking with your vehicle’s operational guidelines will explain the type of oil best suited for your car’s engine and why it’s recommended.

In general, traditional motor oil is still used in many vehicles because it’s cost effective, it’s easy to find, and it works well, especially in older cars in excess of 75,000 miles on the odometer.

What is synthetic motor oil?

Regular vs Synthetic Motor Oil - What You Should KnowSynthetic motor oil is a human-made lubricant created by artificial chemical compounds as a substitute for petroleum-based oils.

Synthetic oil was first developed back in 1929 as a response to needs during World War II. In the 1970s, better artificial oils were produced to give engines better fuel economy during a time when petroleum-based products were skyrocketing in price.

The process of producing synthetic motor oils has been perfected to where today, some engines perform better with these new lubricants than with more traditional oils. Although synthetic oils were once created to benefit high-performance vehicles, today’s technological advances have made automotive manufacturers rely on them for better fuel efficiency.

Visually, regular and synthetic motor oils may look the same, but fundamentally they perform differently. Petroleum-based products are thicker at lower temperatures and thinner as things heat up. To change the viscosity, manufacturers add different additives to make traditional motor oil perform better under different circumstances.

Synthetic motor oils are designed to behave in certain ways right from the start. That means they don’t degrade or change viscosity over time, other than degrade as it circulates through the engine and picks up contaminants over time.

Synthetic oil will provide better engine protection, will last longer, and comes in advanced formulas that might be specifically made for your vehicle’s engine. This is where it’s important to understand what your vehicle’s manufacturer suggests, and stick with the recommended schedule.

Is synthetic motor oil better for your engine than regular motor oil?

In a word, yes. Although a traditional petroleum-based lubricant will do the job well, it can’t compete with the lab-created motor oil created specifically for engine performance.

Synthetic based motor oils use higher quality oils than traditional products. That makes them more chemically stable, less likely to oxidize and acidify, and slower to break down and lose their protective qualities.

That gives your engine better protection while allowing better performance at the same time. You’ll find synthetic motor oils can combat sludge and deposit buildup, reduce wear and tear on your engine, as well as control breakdown no matter what your driving conditions are like.

Chemistry makes the difference, especially in today’s technology-driven performance vehicles.

Does synthetic motor oil have more advantages over regular motor oil?

Synthetic motor oils were created with a specific purpose in mind: to protect the engine and make it perform as well as possible. That’s something crude oil can never do, because manufacturers simply adapt to the qualities of the oil already in place. Synthetic motor oils:

Protect the engine better – as the engine operates, parts are in constant motion and connection with each other. If they do so with a protective barrier between them, the engine will perform better and stay operational longer.

Keep the engine cleaner – when oil circulates through the system, it can pick up particles and contaminants that break down the functionality of the oil. These can damage your engine over time. Synthetic oils are created with this process specifically in mind, meaning they’ll stay cleaner longer in everyday driving situations.

Flow better in low temperatures – when your car is at rest, motor oil stops along with it. It takes time when the engine starts to circulate the oil back into the system, and start protecting various parts. In cold temperatures, that process can slow down, putting the system at risk.

Protect better in high temperatures – an engine in operation runs hot. When you add in heat from the environment, it gives more risk to the parts underneath the hood. This increases as you navigate the Rocky Mountains, especially if you pull a boat or trailer. Synthetic oils are made for that type of driving.

My owner’s manual states regular motor oil is fine. Should I upgrade?

Switching from regular motor oil to synthetic is perfectly acceptable and can help your engine in many ways. You’ll find synthetic motor oils built for different situations – just ask one of our mechanics which would be best for your vehicle.

However, if your older car has high mileage, it may still be beneficial for you to use traditional oils. If an engine has never used synthetic oils, has been poorly maintained, with infrequent oil changes, we would recommend sticking with conventional oil.

The key is always to provide the proper maintenance based on what your vehicle needs most.

Do You Really Need To Change Motor Oil Every 3,000 Miles?

by

Driving a car means you have to perform a few maintenance tasks along the way to keep it running well. We know we have to fill it up with gas, or it will die. We understand motor oil is necessary to keep the engine running. We need new tires, or we put the passengers inside the cabin at risk.

But when?

Everything comes with a warning sign. As that little needle gets closer to E, you’re aware if you don’t stop at a gas station, you’ll be stranded along the side of the road.

Popular guidance tells you to replace the oil in your car every 3,000 miles. But is that the best advice?

Do you need to change your motor oil every 3,000 miles, or is there some other way to evaluate when it’s needed?

What motor oil does

What does motor oil do inside your vehicle? Most of us know that motor oil keeps your car running, but it does a lot more than that.

Today’s motor oil is a complex mixture of oils and additives that accomplish a variety of things under the hood. It:

  • Lubricates moving parts
  • Helps reduce engine wear
  • Removes dirt and contaminants from the oil
  • Cools engine parts
  • Enhances fuel efficiency
  • Protects the engine against heat and cold
  • Helps protect the emission system

Do You Really Need To Change Motor Oil Every 3,000 Miles?Without the proper motor oil inside your vehicle, it’ll quickly wear down various parts.

Every time you start up your car, the combustion process degrades your motor oil. It adds contaminates to the oil supply, which over time, builds up. In the beginning, motor oil can handle it without issue. But as it wears, it continues to break down, turning into sludge that can harm your engine.

That’s a lot for a few cans of motor oil to handle. That’s also why it’s essential to change it out regularly.

But is it important to change motor oil every 3,000 miles?

Now that you know why changing out motor oil is important, let’s get back to the question of how often.

It doesn’t take a lot of searching online to discover there are many different views on how often you should change out your motor oil. But who’s right?

Start by looking at the source of information.

Quick-lube places will tell you to change your oil every 3,000 miles. They even give you little stickers as a reminder.

It’s important to consider the source, however, before you take their advice. Quick-lube stores offer one service: motor oil changes. That means they have a vested interest in getting you in as much as they possibly can. They are also usually sponsored by a particular brand of motor oil. Again, it’s all about the sales.

Another resource to look at is your own vehicle’s manufacturer. If you check your owner’s manual, you’ll likely find they make their own recommendations. With today’s technology, a lot of them recommend an oil change every 5,000 to 7,500 miles.

That’s a lot different than the 3,000 miles.

But there’s another thing to consider. In most cases, it’s not about how many miles you drive, it’s also about the timeframe between oil changes. For some drivers, it may take a year or more to hit the 3,000 miles. Others may hit that mile marker in a matter of days.

Driver A works from home and only takes their car out to run errands. They drive ten miles or less at a time, with constant starting and stopping. With frequent stops, the motor oil never heats up enough to boil off the moisture condensation. That means more engine wear over time. They shouldn’t pay attention to the 3,000 rule, but should instead change it out twice a year or so.

Driver B has a long commute, driving more than 20 miles one way that consists of mostly highway driving. With this slow and steady drive time, they could easily push the upper edge of what their vehicle’s manufacturer recommends.

In both cases, as the car ages, more frequent oil changes may be in order. Remember, the key to keeping your engine running well is clean performing motor oil. It’s one of the least expensive ways to ensure your car stays running smoothly.

What type of motor oil should I use?

All motor oil is not the same. Which motor oil you use in your car should be determined by a variety of factors, including the climate you live in, your driving habits, as well as the age of your vehicle.

When you bring your vehicle into our service station for an oil change, you can discuss which type of oil you prefer to use for your engine. We’re here to give you advice every step of the way.

In general, there are four types of motor oil:

Synthetic motor oil – this is ideal for high performance vehicles. It provides higher viscosity levels and helps fight oil sludge.

Synthetic blend motor oil – this is becoming increasingly popular as it combines both conventional motor oil with synthetic. It offers extra resistance to oxidation, and more protection against lower temperatures.

Conventional motor oil – this is ideal for older models cars that have operated on this type of motor oil for years.

High mileage motor oil – This is specifically blended for vehicles that have exceeded 75,000 miles. It helps minimize leaks and reduces emissions.

When was the last time you changed your motor oil?

To work out a plan that works well with your vehicle, talk with one of our mechanics today. We can give advice on how often it should be replaced, and what type of motor oil to add to your vehicle’s system each visit.

What Happens If You Don’t Change Your Car’s Motor Oil

by

One of the very basic items to keep your vehicle running is motor oil. Outside of gasoline, it’s the number one thing you’ll change out on a routine basis.

But as you buy another can, or drive into your local service station for a motor oil change, have you ever wondered what would happen if you skipped it altogether? What if you waited a few months? What if you didn’t follow the guidelines? How bad could it be?

Many of the guidelines state that a car’s motor oil should be changed every 3,000 miles or 3 months, whichever comes first. If you check your owner’s manual, depending on the vehicle you drive, it may push that up to 5,000 or more.

What should you believe?

What motor oil does

Before we get into how frequently you should change it out, let’s talk for a moment about what it does.

Motor oil has one purpose: it’s designed to keep your car running smoothly. It’s designed to lubricate the engine and help carry heat away from the engine compartment. As the motor oil circulates throughout the system, it continuously lubricates the thousands of parts that come together and make your vehicle operational. And at the same time, it helps dissipate heat, carrying it away from where it can do the most harm.

What Happens If You Don’t Change Your Car’s Motor OilThat makes motor oil pretty important, right?

Think of motor oil as the lifeblood of your vehicle. If it doesn’t have a high quality supply running throughout the system, it can function at peak performance. And that means things will start to wear down over time.

Fresh, clean motor oil will keep your car in its best possible condition.

If it degrades, your car will start to wear down.

What really happens without fresh motor oil?

Glad you asked. It’s important to keep in mind that every car reacts in its own unique way. Your car won’t suddenly wear out without new motor oil at 3,001 miles. It’s more of a gradual process.

As motor oil works and moves throughout the system, it picks up all kinds of dirt and debris. If it’s working well, it can push this debris away from the moving parts and into an oil filter. But if you don’t replace the filter (it’s part of a regular oil change), the filter will eventually become too clogged to do its job. That means whatever the motor oil pushes in, it bypasses it and leaves it within the system.

That’s when engine parts start to wear down. Instead of fresh, clean motor oil, dirty fluid is circulating throughout the system. And it might not be doing a very good job. It can be abrasive, causing parts to rub together in wrong ways. It might not keep each part properly lubricated.

Motor oil isn’t just oil. Instead, it’s a combination of oil and additives designed to keep your car running at its best. It has things like detergents, dispersants, rust-fighters and friction reducers all working together to provide your vehicle with what it needs to thrive. You know when you’re washing dishes and the soap bubbles eventually dissipate because of all the grime that makes its way into your sink? That happens to motor oil too. The additives can’t work the way they did when you first added motor oil to the system, not once the system is compromised.

So the oil gets thicker, dirtier, and loses the ability to do what it was designed to do – keep heat out of the engine compartment. Heat builds. Parts warp. Damage starts to occur. And your car might not drive quite the way it did before.

But you still might notice anything. You might continue driving.

This turns oil into sludge. The volume of dirt and grime becomes too much, and it can’t process it at all. It barely moves, loses most of its lubricating qualities, and brings no relief to your vehicle’s parts.

If you leave it this way for too long, the engine will seize, and stop working altogether.

A high quality motor oil change is something you’ll barely notice in your monthly budget. We guarantee you’ll feel the pain of replacing a seized engine. It can cause thousands of dollars to bring your car back into working condition.

What else happens along the way?

Now that you know what happens within the engine compartment itself, let’s talk about a few other things you should know.

Did you buy a new or used car with a warranty? The warranty is only good if you follow the rules. And if you read the fine print on the warranty itself, you’ll find that it states you have to service your vehicle according to a schedule. If you don’t service it according to factory guidelines, the warranty will be null and void. Yes, that means you should keep track of every motor oil change you do. For that matter, you should keep a record book of every maintenance item you do, just to be able to refer back and determine all that you’ve done to your vehicle over the years. It can also be something that gives you an edge when trying to sell it down the road.

And long before you face a seized engine, you’ll also find your vehicle shows poor engine performance. When detergents and lubricants aren’t working correctly, you’ll hear and feel your engine sputtering. It can materialize as poorer gas mileage too.

It’s time to change your motor oil today

There’s an adage: an ounce of prevention is worth a pound of cure. And while that’s true for every system in your vehicle, it definitely applies here.

If you want a car that continues to operate well throughout its life, giving you the longest lifespan possible, it’s important to keep it working well.

You can do that easily just by pulling into our service station on a regular basis. Three or four times a year, for most.

It’s not about the money you’ll spend on new motor oil. It’s about the money you’ll save on repair bills down the road.

Simple Answers: Check Engine Light

by

Question:  My check engine light is on and my boyfriend thinks he can get the code read and know what part to replace to fix my car.  I say it’s not that simple.  Who’s right?

Answer:  The simple answer is you are! But let’s look at it logically and break it down.  There are hundreds of things that can go wrong with your vehicle.  Some are simple but some are actually quite complicated.

In today’s vehicles over 80% of engine functions are computer controlled.  The computer receives information from dozens of sensors.  When a sensor reading is out of range, a trouble code is automatically entered in the computer and the check engine light is illuminated.

Unfortunately it’s a common misconception that the trouble code will tell you exactly what is wrong.  Because the truth is, that for any given trouble code, there are any number of faults that would trigger that code.  For example, a code indicating a misfire on cylinder three could be due to a bad spark plug, a failed coil, ignition problems, compression issues, etc.  Each of those possibilities requires additional diagnosis to confirm or rule out a cause.  Once a trained technician with state-of the art diagnostic tools and access to extensive research databases, can then nail down the problem, and set about getting it fixed.

A complicated diagnosis may take some time.  Your boyfriend might be tempted to bypass a diagnosis charge by taking a trouble code reading with an inexpensive scan tool and start replacing parts.  He might get lucky, but chances are he’ll end up like a recent customer who ended up spending hundreds of dollars on parts that weren’t needed and didn’t fix his problem because he tried reading the code himself.  So save yourself time and money and have a professional with the right equipment check your vehicle.

Just one more thing… a flashing Check Engine Light indicates that a condition exists that could lead to serious damage.  You should get to your service center right away.  A steadily illuminated Check Engine Light is less urgent but still needs to be checked out.  Keep in mind that a minor issue today can become more serious if left unresolved.

Change Your Oil, Drivers!

by

As engine technology advances, recommended oil change intervals have gotten longer.  High quality oil in a well-engineered engine has led to extended intervals.

Here’s the problem:  With longer oil change intervals, it’s extremely important to follow them closely.  Back in the day of 3 months or 3,000 miles, if you went an extra month or an extra thousand miles, your oil was still fresh enough that it didn’t have time to build up much sludge.

But if your recommended interval is 6,500 miles and you go over another thousand, you’re getting into heavy sludge territory.  This can cause big problems.

You absolutely need to follow mileage intervals on changing your oil very closely.  And don’t forget your severe service schedule.  If you do a lot of stop and go driving, short trips, drive in dusty or polluted conditions, hot or cold weather, or haul heavy loads, you’re driving in severe service conditions.  Is your driving closer to the regular schedule or the severe service schedule?  It’s your call as the driver to decide when to change your oil to protect your engine.

If your car came from the factory with synthetic oil, the recommended oil change interval is for synthetic oil.  If you use conventional oil, you shouldn’t be using the synthetic oil interval – you need to shorten it.

Service advisers often report that when they talk to a driver with 200,000 miles or more on their vehicle, the vehicle owner will say their secret is changing the oil on time.  Please don’t skip an oil change.  Once sludge has started to build up, it’s tough to get it out.  So don’t let that happen to you!  Change your oil, drivers!

Signs Your Car Needs An Oil Change

by

It’s hard to ignore that your car needs gas to operate. If you don’t add more when the gas tank is low, you run out. And when that happens, your car stops working. It comes to a grinding halt, and you’re stuck wherever it happens … until you fill up the gas tank once again.

But what about car oil? It works in a similar manner. Your car needs oil to operate. If it runs out, your car will cease to operate. And a lot of damage will occur to the working parts of your car.

Yet a lot of car owners are ignoring this important fluid. If they have a newer car, they assume the electronics will tell them when things aren’t working. They drive and drive, almost waiting for a problem to slow them down.Signs Your Car Needs An Oil Change

As a result, repair shops all over are finding more vehicles than ever are coming in with engine damage. If the engine doesn’t have the proper fluids, it operates as best it can. Until it can’t. And a lot of problems occur in between.

What does car oil do?

For a car to operate as it should, it’s important to perform routine maintenance. That consists of an oil change, draining the old oil out and replacing it with fresh, new oil. An oil filter is usually replaced at the same time.

Cars have lots of moving parts in them. They are designed to move together, causing friction and heat. Car oil lubricates the engine and absorbs this heat, which lets all the internal parts work together without the chance of overheating.

This, of course, is a constant process of sending the oil throughout different parts of the engine, collecting dust, dirt, and other particles as it performs its task. The older it gets, the more it breaks down, unable to perform as it was originally intended. It becomes less effective at lubricating all the parts within the engine.

How often should you change car oil?

That depends on what car you drive.

Every owner’s manual for every car manufacturer will list specific guidelines for how often you should replace your oil. Be aware that not every motor oil is the same. You can’t run to your local discount store and pick up a can of oil and expect it to work for your vehicle. In fact, doing so can be downright dangerous.

According to the American Petroleum Institute, there are many different motor oils for sale in retail locations for the average DIYer that will cause more harm to your engine than good.

Your car requires a certain type of oil created for how your vehicle was built. This is where following manufacturers guidelines is an important part of your car’s maintenance routine. American built cars have different requirements than European cars, with the latter often requiring more rigid specifications.

When it comes to your motor oil, err on the side of selecting the best. Pay attention to what the car’s designers have to say, because it can help you avoid a costly mistake.

What is synthetic car oil?

Even if you have an older car, we think an upgraded oil is still beneficial for your car. Here’s why you should consider moving to a synthetic car oil.

Synthetic oil is made from natural gas or crude oil that goes through a rigorous process to convert it to motor oil. This process makes all of the molecules uniform in size. That means it flows through your car more uniformly. It reduces the amount of friction produced as it operates, reducing the wear on your engine.

If you use name brand, higher quality motor oil, you’ll have a better product. And with a better product means your engine will have a longer life. Is it worth a few dollars now to keep your car running well for years to come?

But what about older cars? Should you always buy upgraded oil? 

If you have a car and it’s been going strong for over 100,000 miles, it’s hard to argue that it’s been working fine with more conventional motor oil. Why not give it just the basic grade?

As your car ages, it starts showing signs of wear. Even the parts you can’t see unless you really look.

That may be precisely why it’s a good idea to upgrade your motor oil. Giving it a far superior product now means you’ll be giving it better fuel for operating. You know how you feel better when you eat, right? It’s the same for your vehicle; give it a higher quality product, and it will perform better over time.

What should I watch for to determine when I should change the oil?

Now that you know why your car needs motor oil and what you should be putting in, how do you know it’s time?

Mileage

Check your vehicle’s owner manual. Manufacturers list how often you should change your motor oil based on how many miles you put onto your car. This is a good guideline to follow to ensure you’re changing your oil regularly.

Dates

It’s also a good idea to pay attention to how you drive. Have you taken a road trip recently? Have you put on excessive miles in a short period of time? Or has your car been stuck away in a garage for months as you work from home? Paying attention to what you do in between oil changes will ensure your car always receives fresh oil.

Check engine light

Never ignore the little lights that pop on your dashboard. They illuminate for a reason. Some cars have oil change lights, while others may flash “check engine” instead. Proceed to your mechanic as soon as possible to avoid bigger problems.

Noise

Motor oil provides lubrication, a protective layer as engine parts move and operate. If it doesn’t have enough to do its job, you’re going to start hearing noises. That knocking, banging, clanging, or rumbling noise is trying to tell you something. Don’t ignore it.

Denver: Have You Considered Synthetic Oil?

by Leave a Comment

Denver: Have Your Considered Synthetic Oil?After recently seeing an ad for synthetic oil in Denver and realizing I didn’t know much about it.  I asked my helpful Express Car Care service adviser for some background.  Basically the inside of your engine gets really hot because of friction from the moving parts and from burning fuel.  Oil lubricates the moving parts to keep them from getting too hot.

The problem begins when oil turns to sludge, which is kind of a thick jelly.  Sludge clogs up little passages so that the oil can’t protect parts of the engine.  So the two best ways for Denver car owners to prevent sludge build-up is to always change their oil on schedule, and to use synthetic oil.

Synthetic oil is much more resistant to becoming sludge than conventional oil.  My service specialist says it has the added benefit of lasting longer than conventional oil so the recommended change interval can be slightly longer.

The thing I think is cool is that synthetic oil is more slippery than conventional oil.  Regular oil molecules are long chains where synthetic oil molecules are rounder.  It’s like which is more slippery, a pile of pencils or a pile of marbles?  This means that synthetic oil does a better job of lubricating my engine so it doesn’t get as hot, or wear out as fast.

Using synthetic oil can help Denver motorist improve engine performance and help their engine last longer.  I’m really glad my service adviser filled me in on synthetic oil.  Maybe you should consider synthetic oil for your next oil change.  Give us a call at Express Car Care and let us help.

The Maintenance Mindset: Full-Service Oil Change

by Leave a Comment

The Maintenance MindsetPeople generally accept that many things in life require regular maintenance:  their teeth, clothes, homes, yards and so on, but Colorado motorists don’t often apply the same idea of maintenance to their vehicles.  If you never brush your teeth or go to the dentist, you’ll become painfully aware of your neglect when you get a big cavity.  Once the damage is done, we learn our critical lesson and start to take better care of things.

Unfortunately, Denver people too often learn the hard automotive lesson only after they bring their vehicle to Express Car Care on a tow truck.  So many times, a little routine maintenance would have prevented an expensive breakdown.

So how do Denver car owners get into the habit of taking care of their vehicles?  It’s so easy to forget it’s not like cutting the grass which you can see every time you pull in the driveway.

Here’s something that will help:  The key to good vehicle maintenance starts with the oil change.  Think about it – when you go in for a full-service oil change in Denver, your cheerful Express Car Care service adviser will check all your fluids.  If one of them is low, he can look for the reason why.  If your serpentine belt is worn, he’ll see it and let you know.  Corroded battery cable – they’ve got you covered.  And they’ll check to see if your manufacturer has recommended any critical services at your current mileage.

The oil change becomes kind of a focal point, a way to check in to see what needs to be done.

The fact is that vehicle inspection surveys consistently reveal that over 80% of vehicles have one or more needed repair or maintenance service that goes undone.  Vehicles are generally very reliable and can take a lot of abuse and neglect – but you can only press your luck for so long.

So when you come into Express Car Care for an oil change, you get a visual inspection of your car and a reminder for recommended services so you can avoid a total failure.  Also keep in mind that your service professional can help you work out a maintenance and repair plan for your vehicle, prioritizing and scheduling the work to make sure you and your family are safe and help you avoid expensive breakdowns.

In addition to full-service oil changes, at Express Car Care we also offer air conditioning service, transmission service and tire rotation.

The Express Car Care Guide to Synthetic Oil

by Leave a Comment

The Express Car Care Guide to Synthetic OilSynthetic motor oil has been around for a long time in Denver and more and more new cars are leaving the auto manufacturers factories with synthetic oil in their engines.  But a lot of car owners still don’t really know much about it.

Let’s start with conventional oil – the kind Denver folks are familiar with using in their engines.  Conventional oil is made up of naturally occurring hydrocarbon chains, which means its molecules are long and have various lengths, ( like a pile of pencils ), some of them are new and some of them are used.

Synthetic oil is man-made.  Its molecules are more uniform and regular in shape -more similar to marbles than pencils.  Some synthetic oil starts with a petroleum base that’s modified and others are entirely synthesized from other materials.

Synthetic motor oil works best in both hot and cold Denver temperatures.  It’s more chemically stable so it doesn’t readily evaporate or breakdown in the high heat produced inside your vehicles engine.  This means it resists turning to sludge, which is a real engine killer.

Remember the marbles and pencils thing we were talking about?  Well, that makes synthetic oil more slippery than conventional oil which means less friction in your engine when you use synthetic oil.  Your vehicle’s engine runs cooler, wears less and lasts longer.  You also get a boost in power and maybe even an improvement in fuel efficiency.   Synthetic oil also lasts longer so you change it less often – which is great for the environment.  With longer oil change intervals, you will need to use an oil filter specifically built for the longer service life of synthetic oil.  Talk with your cheerful Express Car Care service professional about synthetic oil and synthetic blends -they might be just what you need to improve engine performance and extend the life of your vehicle.

Oil Change Intervals

by Leave a Comment

Quick lube businesses and their employees have often been accused of recommending “unneeded” oil changes so they can make more money.  That may be true for some businesses, but when we service a car, we only recommend services that we believe are necessary to keep your car running at its best.  Here are some of the reasons why we encourage an oil change interval of 3,000 miles or every three months.

In recent years, many vehicle manufacturers have extended their recommended oil change intervals to 7,500 or 10,000 miles.  They have good intentions of trying to help reduce the maintenance costs for car owners, but they have run into trouble.  The Center for Auto Safety has gotten thousands of complaints from drivers who thought they were following the correct oil change  intervals in their owners manuals but ended up with a crankcase full of sludge.  Motor oil does more than just lubricate the engine.  It also forms a film on surfaces that separates moving parts so they don’t rub against one another, reducing friction and wear.  Oil also serves as a coolant for critical engine parts like the crankshaft and valve train.  It also helps to prevent rust and corrosion from building up inside the engine and keeps surfaces clean by dissolving and carrying away dirt and deposits.

Extended oil change intervals of 7,500 to 10,000 miles are based on “ideal” operating conditions, not stop and go driving, or driving our cars for several short trips, like the majority of drivers do each day.  So most drivers should be following a severe service schedule rather than a normal schedule to better protect their engines.  Most experts still consider a 3,000 mile or six month oil change interval the best for “severe” drivers.

Customers at our shop have also told us that they think because motor oils are of a higher quality than they once were, they don’t need to change the oil as often.  This would be a valid argument if oil filters had also improved in quality as well, but unfortunately they haven’t.  An engines main line of defense against abrasion and the wear caused by it,  is the oil filter.  The oil filter’s job is to remove solid contaminants like dirt, carbon, and metal particles from the oil before they can damage surfaces in the engine.  If your oil filter is clogged, it can’t do its job and unfiltered oil will enter the engine.  Contaminants  that find their way into the crankcase will be pumped through the engine and accelerate wear.

Although motor oils have been improved and are continuing to be improved, there hasn’t been much done to improve oil filters.  The majority of oil filters still need to be replaced every 3,000 miles, so until the oil filters have been improved as well, we will continue to recommend a 3,000 mile or three month oil change interval.
