Tesoro’s Los Angeles refinery is located in Wilmington, Calif., on approximately 300 acres in the South Bay of the City of Los Angeles. At approximately 97,000 barrels per day, it is the third largest refinery in Tesoro’s system. The refinery was acquired by Tesoro in May 2007 and processes heavy crude from California’s San Joaquin Valley and Los Angeles Basin as well as imported crudes from South America and other international sources via the Port of Long Beach. The refinery manufactures gasoline, jet fuel, diesel fuels, petroleum coke and fuel oil. 

The refinery has a rich history that dates back to the early 1900s. Since then, it has expanded and improved its operations to meet the increasing demand for clean petroleum products and to respond to new environmental regulations. In California, the refinery was one of the few diesel manufacturers that produced a cleaner burning diesel fuel before the California Air Resources Board adopted a regulation requiring low-aromatic content diesel. The adjacent Wilmington sales terminal receives petroleum products from the Los Angeles refinery. The terminal features a four-lane bottom-load rack, which distributes 32,000 barrels per day of all grades of gasoline and low-sulfur diesel primarily to Tesoro’s Shell® and USA Gasoline™ stations. Tesoro also distributes products through purchase and exchange agreements with other refining and marketing companies.
