Headquartered in Dallas, Texas, the company combines more than a century of refining heritage from Sinclair Oil—founded in 1916—with HollyFrontier’s expertise in downstream energy operations.

In addition, the company produces a suite of specialty products including base oils, asphalt, waxes, and specialty lubricants that serve industrial, automotive, and consumer markets.
Beyond refining, HF Sinclair’s integrated logistics and marketing platform supports the transportation and sale of its products through pipelines, terminals, railcars, and a network of roughly 1,400 retail locations operating under the Sinclair and HF Sinclair brands. The company’s marketing arm leverages its iconic Sinclair dinosaur logo and decades-old brand recognition to serve wholesale and retail customers across 28 states and western Canada.
