Base oils are the building blocks used to manufacture lubricants, such as motor oils, for consumer and commercial uses.

Chevron's ISODEWAXING® catalyst revolutionized base oil quality. Virtually all of the world's premium base oils are produced using this isomerized dewaxing technology. Due to their purity and oxidation stability, Chevron premium base oils enable lubricant blenders to cut costs while meeting stringent specifications for cleaner-burning engines.

We work closely with lubricant manufacturers, additive companies, equipment manufacturers and industry groups such as the American Petroleum Institute, European Automobile Manufacturers' Association, International Lubricant Standardization and Approval Committee, and Society of Automotive Engineers to advance industry standards that protect engine performance while enabling environmental compliance for new engine designs.

We produce premium base oils at two strategically located refineries, in Richmond, Calif., and Yeosu, South Korea. Preparations are under way at a third plant, at our refinery in Pascagoula, Miss. The facility is scheduled for startup by the end of 2013. When it is completed, Chevron will be positioned as the world’s leading premium base oil suppler. Our premium base oils are shipped to regional supply hubs in the most significant lubricant markets.
