About Tesoro Corporation

Vision Statement

Every day we create a safer and cleaner future as efficient providers of reliable transportation fuel solutions.

Who We Are

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.

What We Do

Tesoro safely, efficiently and reliably operates an integrated network of strategic assets that create and sell refined petroleum products, from feedstock acquisition to wholesale, commercial and retail sales outlets.

At our refineries, Tesoro refines crude oil and other feedstocks into transportation fuels, such as conventional and CARB gasoline, diesel fuel, jet fuel and other petroleum products, including heavy fuel oils, liquefied petroleum gas, petroleum coke, calcined coke and asphalt.

Our marine operations charter U.S.- and foreign-flagged tankers to optimize the transportation of crude oil, other feedstocks and refined products within our refinery system.

Through our retail and marketing operations, Tesoro sells refined petroleum products in 17 states via commercial, wholesale and retail channels. Commercial marketing trades in commercial and military jet fuel and heavy fuel products. Our wholesale program markets gasoline and diesel fuel to independent marketers, commercial end-users and high-volume retailers. Our network of retail stations sells gasoline and diesel fuels and convenience products directly to consumers under the Tesoro®, Shell®, ARCO®, Exxon®, Mobil® and USA Gasoline™ brands.

Tesoro Corporation formed a master limited partnership, Tesoro Logistics LP(NYSE: TLLP), which has a significant presence in gathering, transporting, storing and distributing the crude and other feedstocks we refine. Tesoro Logistics LP assets include:

  • Twenty refined products terminals and storage facilities in the western United States,
  • Four marine terminals in California,
  • A rail-car unloading facility in Washington,
  • A petroleum coke handling and storage facility in California,
  • The High Plains system that gathers and transports crude oil produced in the Williston Basin, including production from the Bakken Shale formation,
  • The Northwest Product Pipeline that runs from Utah to Washington (including a 5-mile segment to the Salt Lake City International Airport), and
  • Other pipelines that transport products and crude oil from Tesoro’s refineries to nearby facilities in Utah and California.

Fast Facts

Tesoro was founded in 1968 as a company primarily engaged in petroleum exploration and production. In 1969, we began operating our first refinery near Kenai, Alaska, which today remains an important part of our expanding operations.

In the late 1990s, Tesoro began a series of refinery, logistics and retail acquisitions that have boosted the company’s capacity output, improved the efficiency of our operations, increased our retail presence and positioned us for future expansion in key growth markets. During this time, we also exited the exploration and production business.

    I have been working at Tesoro Corporation full-time (More than 3 years)


    R.A.M. was helpful, vendor relations were good, Upper management was good, good emphasis on safety.


    Middle management was iffy, new ownership slashed labor budgets and caused all but 2 mgrs to leave. Seemed to want to bring in lower priced talent as replacements.

    Advice to Management

    Tesoro should take back its retail operations if it is not too late. New ownership was horrible.

    Easy Interview


    I applied through a recruiter. The process took 6+ weeks. I interviewed at Tesoro Corporation.


    I was actually recruited for this position, so I can’t speak to how long it takes Tesoro to call you back once you’ve submitted an application. For the interview: 1 - I had an itinerary emailed to me that filled an entire afternoon – each interview session was 30 minutes. Keep in mind that this was for an “experienced professional” position – not management or any tier higher. I had to take time off from my current job to interview. Not a huge deal for me personally, but it was not exactly ideal. 2 - The recruiter scheduled me on top of another candidate, whom was interviewed first. We started about 20 minutes late and consequently, it pushed back every other interview I was scheduled for. 3 - All the interviews were 2 people, with the exception of the recruiter and a VP interview. None of the questions were very difficult. In fact, most of the interviews were highly conversational and felt more personal rather than a “Tell me about a time when…” 4 - There were a hodgepodge of questions I answered, leading me to believe they didn’t really know what they wanted in a candidate, or every single interviewer was unprepared. One interviewer mentioned not needing a qualified HR person, but rather someone who could meet deadlines, which left me with mixed confidence in the role. Good luck to others!
