Base oils are the building blocks used to manufacture motor oils and other lubricants for consumer and commercial use.

Chevron’s ISODEWAXING® catalyst revolutionized base oil quality. More than half 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 three plants. One is in Richmond, California, and another is at our joint-venture refinery in Yeosu, South Korea. And in 2014, we started up the third plant, at our refinery in Pascagoula, Mississippi. With the addition of the Pascagoula Base Oil Plant, Chevron has become the world’s leading producer of premium base oil. Our premium base oils are shipped to 14 regional supply hubs in significant lubricant markets.
