Many people are unsure whether or not they should be using synthetic or regular oil in their vehicles. It depends on the recommendations of the carmaker, the mileage, and the age of the car.

Cars that are older and have higher mileage usually have a large amount of engine wear that can cause oil to leak internally. Synthetic oil is not usually recommended for these cars because it flows freely and is thinner than regular oil. Using it often can cause internal oil combustion.

A lot of carmakers today use synthetic oil in their engines. Usually it is used when the car has a high-performance engine with high compression, engine tolerances that are tight, and high temperatures for operating. If you are considering making the switch to synthetic oil and your car is still under an auto warranty, be sure to talk to your dealer first.

In the correct car, synthetic oil can be a smart idea. However, be sure to consult your owner’s manual first. Even though synthetic oil is twice as expensive as regular oil, it is worth it because it lasts longer and will help your engine last longer as well. Also, it can help you avoid needing to make road service calls.
