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, including the American Petroleum Institute, the European Automobile Manufacturers' Association, the International Lubricant Standardization and Approval Committee, and the 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 plants, one in Richmond, California, and the other at our joint-venture refinery in Yeosu, South Korea. Construction is under way on a third plant, at our refinery in Pascagoula, Mississippi. We are scheduled to be done with the building and assembly phase by the end of 2013. When it is completed, Chevron will be the world's leading premium base oil producer. Our premium base oils are shipped to regional supply hubs in significant lubricant markets.
