A proud tradition was born on May 1, 1916, when Harry Sinclair formed Sinclair Oil from the assets of eleven small petroleum companies. Sinclair quickly grew to become the seventh Sinclair Stationlargest oil company in the United States. The original Sinclair Oil Company began marketing the apatosaurus (brontosaurus) in 1930 and now after more than 75 years, "Dino" still remains one of the most recognizable corporate logos in the world.
Sinclair is a Wyoming corporation with two refineries and most of its employees located in the cities of Sinclair and Casper, Wyoming. Sinclair provides fuel and lubricant products to 22 states, throughout the Great Plains and Rocky Mountains, making the Sinclair brand a prominent and welcome sight to the motoring public.
