USA Gasoline stations are owned by the Tesoro Corporation, a company that operates six refineries in addition to selling gasoline at a variety of differently branded retail stations, including Shell, Exxon, Mobil and ARCO. The USA Gasoline brand and its 138 retail locations were acquired by Tesoro in 2007.
Tesoro, which takes its name from the Spanish word for treasure, was founded in 1968, and it was primarily focused in petroleum exploration and production. Beginning in 1998, Tesoro began an expansion, acquiring five refineries as well as different retail outlets, beginning with USA Gasoline. The majority of Tesoro's operations are in the western United States, and the company is headquartered in San Antonio, Texas.
