Engine Oil Changes

The interval at which you need to change your engine oil depends on how many miles you drive, the size of the engine in your car, and what kind of engine it is. A general rule is to change your oil every 3 months or 3,000-4,000 miles regardless of mileage. The more you drive the shorter time between changes. Selecting an interval that keeps the oil clean will keep that new car feel longer; while saving you money in maintenance costs down the road that would result from inadequate auto care.

just Change your oil

Automotive engines today are better and more effective than the old ones. Newer engines have more moving parts. If you take care of them, they will work well for longer periods of time. The most common reason for engine failure is neglect. You can prevent this by changing your fluids in your car. Another reason people don’t change their oil is that they don’t make time to take it to a repair shop or is inconvenient. The bad news is there are no simple answers to changing engine oil. You just have to do it or risk serious damage.

Follow Manufactured recommendations

You should follow the recommended life cycle for your motor oil. This will ensure optimum performance and protection of your engine’s systems for as long as possible. Vehicles driven under harsher conditions like city driving may need oil changes more frequently than those driven on highways. You may also need to change your oil earlier if the engine is running hot or cold.

Not all cars are the same. Owners of foreign vehicles should consult their manufacturer’s owners’ manual for recommended service intervals and specifications which differ from U.S.-built cars.

While some cars may call for oil changes on a more frequent basis (every 5,000 miles or less), others like the Mercedes-Benz S-Class can go as far as 10,000 miles without a change.

While the recommended oil change cycle may vary from car to car, it all comes down to the type of engine the car has. A basic tenet is that if your vehicle falls under these listed specifications, it is worth changing your oil. It may even be beneficial to change it earlier if you’re the ideal candidate for the “more is better”

Cheaper is not always better

Undoubtedly you can save money if you learn to care for your car yourself, but remember the old adage you get what you pay for! Buy high quality parts, made by the original equipment manufacturer. Always follow manufacturer’s recommendations to ensure engine health and long life; which is crucial when considering replacement costs of engines. Make sure any product specifications match up with the manufacturer’s guidelines before purchasing.

Finally, don’t put off changing your vehicle’s engine oil. Learn how to change the oil in your automobile and guarantee engine longevity, as well as keeping you moving down the road. You could also check around and see if you can get a good price on an oil change.


Will Synthetic Oil Cause Engine Oil Leaks?

I worked at an oil change station. People asked this question every day about synthetic oil. So in this blog, I will try to answer one of the most asked oil-related questions.

Question # 1.

Will synthetic oil cause oil leaks on my engine?

This is not true now but for all of us old-school grumpy guys like me! This was a fact and a problem in the past.

Difference Between Conventional and Synthetic Oil

To better understand this let’s look at the difference between synthetic oil and conventional oil in a simple way. For this example, let’s pretend you were holding synthetic oil molecules in one hand and conventional oil molecules in the other.

Synthetic oil molecules would look like round ball bearings and conventional oil would look like oddly shaped gravel.

Now imagine those molecules flowing along inside your engine, which one do you think would flow better, faster, and with less effort? Obviously the ball bearings.

The Difference is the Reason

The molecules in synthetic oil are more uniform to those of conventional oil, Synthetic oil can move around your engine easier and thru smaller orifices.

This is very important for engines with turbo since synthetic oil can quickly reach these components to lubricate, reduce heat and protect. But in the past, when synthetic oil was first introduced, it was an issue because of these qualities.

Older engine gaskets were made of cork and cardboard, so with the properties of synthetic oil and its ability to flow easier thru smaller orifices oil leaks were a common problem.

It also led to the belief that synthetic oil is thinner than conventional oil (another question I get asked regularly).


With the introduction of modern engine gaskets made of silicone, synthetic rubber, and composite materials that are impervious to oil. this is no longer an issue.


The History of Engine Oil

The history of engine oil is a long and fascinating one. It all started with the first automobiles, which relied on crude oil to run. Of course, the technology of oil production was much different back then, and it was only used for lubrication and fuel.

Early Oils

The first engine oils were made from animal fat, and even whale oil was used at one point. but they didn’t work very well. Soon afterward, mineral oil began to be used instead. This oil was better because it didn’t create as many problems with engine corrosion.

It wasn’t until the mid-1920s that engine oil began to start using petroleum specifically developed for automotive engines, and after World War II new engine oils began to emerge which were capable of bettering engine needs.

Evolution of Oil

In fact, engine oil has come a long way since its early days. Automotive engine oil now uses advanced technology, and engine oils today are capable of meeting all engine needs. Some engine oils also have added benefits as well, such as engine oil that is fortified to fight against engine corrosion or cleaning engine oil that can help your engine run for longer.
In the next few sections, we’ll discuss engine oil from its early days until the present. We’ll also take a look at some of the different engine oils that are available on the market today.

The Early Days of Engine Oil

In the 1940s, synthetic engine oils began to be developed. These oils were made from various chemicals, and they offered a number of advantages over mineral oil. They could withstand high temperatures, they didn’t evaporate as easily, and they prevented engine corrosion.

Since then, engine oil has continued to evolve. Newer oils have been developed that are better at protecting engines from wear and tear. They also help to reduce emissions and engine noise. Now engine oil can be found that is specially designed for motorcycles, racing cars, and even aircraft engines.

Engine oil has come a long way

Engine oil has come a long way since its inception nearly 100 years ago. Keep reading to learn more about engine oil today.

Engine Oil Today

Modern engine oils are made from base oils mixed with additives. Petroleum-based oils are the most common type, but synthetic oils are also available.

The base oil is responsible for most of the engine oil’s properties, such as its viscosity and thickness. The additives are used to improve the oil’s performance in various ways. They can help to reduce engine wear, prevent corrosion, and improve fuel economy.

Engine oil is available in a variety of viscosities

The most common type is 5W-30, which is suitable for most cars. However, engine oils are also available in 10W-40, 20W-50, and even 0W-40 viscosities.

Lower viscosity engine oil is better for cold weather engine use and is has been developed for fuel economy. Higher viscosity engine oil is better for high engine heat and has been developed for engine protection during heavy-duty engine use.

Follow Your Manufactured Recommendations

The best engine oil for your car will depend on its make and model. You can usually find this information in your car’s owner’s manual. If you’re not sure which engine oil to use, ask a mechanic for advice or contact your manufacturer part department.

Engine oil is an essential part of engine maintenance. It helps to protect the engine from wear and tear, and it also improves fuel economy. By using the right engine oil for your car, you can help to ensure that your engine stays in good condition for years to come.

Engine Oil Additives

In addition to these base oils, engine oil also contains a number of additives as well. These can include anti-wear additives, corrosion inhibitors, foam inhibitors, pour point depressants, and viscosity index improvers.

These engine oil additives help to protect your engine in various ways. It can also improve engine performance and engine efficiency and fuel economy. Your engine oil only needs a small amount of these additives, so it’s worth your while to make sure that your engine oil contains modern engine oil additives.
