Synthetic vs. Conventional Oil
Synthetic motor oil is derived from man-made ingredients, while conventional motor oil is derived from crude oil. Thanks to these man-made ingredients, synthetic oils are purer than conventional oils. They're also considerably more uniform in molecular structure than conventional oils. That's why synthetic oils lubricate vehicle engines more smoothly and last longer than conventional oils. Synthetic oil may prolong your engine life -- and it's easier on the environment than regular oil.
- In a study released June 6, 2017, AAA compared multiple brands of conventional and synthetic oil engine oil in eight industry-standard tests: shear stability, deposit formation, volatility, cold-temperature pumpability, oxidation resistance, and oxidation-induced rheological changes.
