Over 4,000 retail sites in the U.S. and Canada sell gasoline branded as Valero, Diamond Shamrock, Ultramar, Beacon and Total. They also produce gasoline in accordance to stringent California Air Resources Board (CARB) specifications.
In 2000, Valero purchased ExxonMobil's Benicia, California, refinery and interests in 340 Exxon-branded service stations in California.
Valero is gradually shifting its focus from being a discount gasoline brand to a premium brand.
