Valero was created in 1980 when the Coastal States Gas Corporation was restructured. The name comes from “Mision San Antonio de Valero,” better known as The Alamo. When it was created, Valero took over the operations of the LoVaca Gathering Company (a subsidiary of Coastal States Gas) and acquired an oil refinery in Corpus Christi, Texas in 1981.
The company divided in 1997 (both kept the name Valero) and acquired Basis Petroleum shortly after. A year later, it acquired a refinery in Paulsboro, New Jersey and in 2000, it purchased an ExxonMobil refinery in Benicia, California.
In 2001, Valero merged with Ultramar Diamond Shamrock and gained control of over 4,700 retail sites in the U.S. and the Caribbean. It expanded even further when it bought Premcor, Inc. to become the largest oil refinery in the U.S. Currently, Valero has a credit card-only subsidiary called DSRM (Diamond Shamrock Refining & Marketing) National Bank, through which it issues Valero gas cards.
