Conventional Oil Versus Synthetic:
What’s the Difference?

Jun 21, 2022

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 Does Motor Oil Do For Your Car?

Motor oil is an absolutely essential lubricant that keeps your engine running. 

Benefits of motor oil for your car

  • Reduces friction and wear for your engine’s many parts
  • Acts as a protector for other vital components in your vehicle
  • Helps minimize temperature extremes of running too hot or cold
  • Increases efficiency to help extend the life of your car or truck

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.

Is Synthetic Oil Better?

Synthetic oil and synthetic blends have fewer impurities and better additives—but what are the actual benefits for your vehicle?

Why Choose Synthetic

  • Better performance in hot or cold weather
  • Greater resistance to motor oil breakdown from oxidation and extreme heat
  • Better fuel economy for your car overall
  • Reduced engine drag that yields better horsepower
  • Less engine sludge, because it has fewer impurities
  • Less frequent oil changes, which saves you time
  • Greater engine wear protection

Synthetic oil and synthetic blends may cost more than conventional oil, but their upside makes them worth it over time.
