Conventional Oil Versus Synthetic:
What’s the Difference?

Share

You may not know which kind of oil is in your car right now, but there are important differences between them that affect your vehicle. Synthetic motor oil and high quality synthetic blends offer a range of benefits over conventional oil. But before we can dive into those differences, you need to understand what oil does for your car.

What Is Synthetic Oil?


Synthetic Oil has two key parts, a base and a mixture of additives that make it more effective. Synthetic oil is more chemically-engineered than conventional oil and has fewer impurities. Conventional oils, and even some synthetic blends, use crude oil as a base. Crude oil generally contains more impurities.

 

About 20% of most motor oil formulas, for both synthetic and conventional oil, are additives. Where the two differ is usually in quality. Synthetic oils and synthetic blends include higher-quality additives that protect and clean your engine, and at the same time do not degrade as quickly between oil changes.
