2. What is synthetic motor oil?

Synthetic motor oil consists of artificially made chemical compounds. Instead of using crude oil, petroleum is chemically changed or sometimes synthetic oil can be derived from raw materials. It can also be made in a lab.

Every car or truck is different. Check your owner's manual or use Search For Part's car look up guide where you will find the oil and transmission fluid capacity for your car or truck.

4. What is synthetic oil viscosity?

The best way to describe viscosity is the thickness of a liquid. For example, water would have a low viscosity while honey would have a high viscosity.

5. What are the benefits or advantages of synthetic engine oil/why use synthetic oil?

There are many benefits and advantages. Synthetic oils rarely cause harmful engine deposits and resist oxidation from extreme temperatures and the oil will flow better in extremely cold temperatures. Also you will have better lubrication which means less friction which reduces wear and tear on your engine and this extends the lifespan of your vehicle. Fewer oil changes because of the great intervals will lead to less waste which is better for the environment. Your engine will also be cleaner.

6. Does my car need or require synthetic oil?

High performance vehicles or turbo engines may require synthetic oil. Check your owner's manual to see if your vehicle needs synthetics. If it doesn't then you can use conventional or regular oil, but consider the benefits and advantages of synthetic oil.

An oil change where you or your mechanic will change the oil and filter to a synthetic oil and the filter will be compatible with that synthetic oil so that you can have a longer drain interval.

9. Difference between synthetic and synthetic blend oil/full synthetic oil vs synthetic blend?

Synthetic oil blends are composed of regular or conventional oil and synthetic oil. The proportions are not clear and the benefits are probably diluted. It would be like saying taking the best nutritious 100% fruit juice and diluting part of it with water.

10. Can you switch from synthetic oil to regular oil and regular oil back to synthetic oil?

You absolutely can. Switching to a synthetic will help your engine with many advantages. If you ever decide to switch back to regular or conventional oil, nothing bad will happen to your engine. You are not stuck with a synthetic forever.

11. Can you put synthetic oil in any car?

Yes, you can safely switch to synthetic oil in your car or truck.
