    • About

      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, our operations extend across 18 states.

      As crude oil sources, availability and costs shift, particularly in the United States, we aim to adapt to these market conditions in ways that benefit the long-term health of our business. We are expanding through strategic acquisition and organic growth, investing in capital projects and partnerships that will help lead to a successful future.

      We are committed to delivering value to all of those invested in our success - the communities where we operate, our employees, our customers, our partners and our shareholders.
