Sinclair Oil Corporation is a long-standing name in the U.S. oil and gas sector, focused on distributing and marketing gasoline, jet fuel, and related products. The company largely sources its supply domestically and relies on seven refineries operated by its parent, HF Sinclair. Through a network of distributors, dealers, and licensees, Sinclair delivers its DINO-branded offerings and TOP TIER gasoline to customers across the country. Its customer reach includes consumers via Sinclair-branded stations and its distribution partners, addressing regional fuel needs and supply reliability. In January 2024, HF Sinclair completed its acquisition of Sinclair Oil, integrating the brand into its U.S. oil and gas operations. In May 2025, the DINO Day campaign expanded from a one-day event to three days.
