For more than 45 years, Tesoro has been serving the fuel transportation needs of the western United States.
We are a leading independent refiner and marketer of petroleum products, committed to operating responsibly in the communities we serve. Headquartered in San Antonio, Texas, Tesoro operates refineries in Alaska, California, North Dakota, Utah and Washington.
Tesoro’s Anacortes refinery primarily supplies gasoline, jet fuel and diesel fuel to markets in Washington and Oregon, and manufactures heavy fuel oils and liquefied petroleum gas. The refinery receives crude feedstock via the Trans Mountain pipeline from Canada, by rail from North Dakota and the central U.S. and by tanker from Alaska and foreign sources.
The Anacortes refinery ships gasoline, jet fuel and diesel fuel through a third-party pipeline system that serves western Washington and Oregon.
Tesoro has 388 full-time employees in Anacortes and is deeply embedded in the local community through participation in a variety of local events and the investment of more than $320,000 in 2015 in support of charitable organizations in Skagit County.
