Crude oil is pumped from the ground and refined to make conventional mineral base oils. Although refining processes may be advanced, impurities remain in conventional base oils that compromise their performance.

Synthetic base oils are manufactured via complex, non-conventional processes, and, as a result, contain far fewer impurities and more uniform molecules, giving them higher stability under extreme conditions.

But not all synthetic motor oils are created equal. Mobil 1 is engineered with more than 16 unique components, custom blended using proprietary processes. The advanced full synthetic formulas are the eighth generation of Mobil 1 synthetic oil technology and represent more than 37 years of synthetic oil research and proven performance, even under some of the toughest conditions.
