Tesoro Corp. is a Fortune-150, publicly traded oil refiner-marketer founded in 1968. Its retail focus started about 15 years ago.

Assembled from various purchases, usually tied to refinery acquisition, Tesoro’s retail segment includes a network of about 1,375 branded retail stations. It also acquired BP’s Southern California refining and marketing business, including the ARCO brand. Tesoro’s other brands include Mobil, Exxon, Shell and USA Gasoline, with about 400 convenience stores branded 2Go. The company also has a large number of non-walk-in gasoline kiosks, including about 65 company-operated sites.
