HeadquartersSalt Lake City
Founded1916

Sinclair Oil Corporation is an American petroleum corporation, founded by Harry F. Sinclair on May 1, 1916. Renowned for its iconic green Apatosaurus (Dino) logo, Sinclair has a long history in the U.S. energy landscape. The company's operations traditionally included oil and gas exploration, production, refining, and marketing of fuels, lubricants, and asphalt. Sinclair operates two notable refineries in Wyoming and markets its products through a network of over 1,600 branded gas stations primarily in the Western and Midwestern United States. In March 2022, Sinclair Oil was acquired by HollyFrontier Corporation, which subsequently rebranded as HF Sinclair Corporation (NYSE: DINO). The Sinclair brand, its refineries, and marketing operations continue as a significant part of HF Sinclair.

HQ Significance:

The Salt Lake City office remains significant as the historical and ongoing center for the Sinclair brand, vital for its marketing presence and operational management in its key regions.

Values Reflected in HQ: The headquarters' location in a professional, modern facility in a key regional city reflects Sinclair's commitment to maintaining a strong brand presence, operational efficiency, and its historical ties to the Intermountain West.

Location:

Sinclair Oil's operations are primarily concentrated in the United States. The company operates refineries in Wyoming and markets its fuel through an extensive network of branded gas stations, predominantly located in the Western and Midwestern U.S. While its parent company, HF Sinclair, has a broader North American reach and participates in global commodity markets, the Sinclair brand itself does not maintain significant international operational offices or a direct retail presence outside the U.S. Its global connection is mainly through the broader energy market activities of HF Sinclair.
