Sinclair products are refined to the industry's highest standards.
Sinclair operates three of the most up-to-date refineries in western America, supplying customers the highest quality Sinclair gasolines, diesel fuel, and jet fuel. The Sinclair Refinery near Rawlins, Wyoming, is one of the West's longest-running industrial plants, yet Sinclair has made it one of the most modern refineries in the Rockies, producing 60,000 barrels of petroleum products per day. Sinclair's Little America Refinery in Casper, Wyoming, refines 20,000 barrels of petroleum products per day.

Over 1,000 miles of pipeline are operated by Sinclair in the Rocky Mountains, moving crude oil to Sinclair refineries and finished product to our marketing terminals.

A history driven with confidence.
Sinclair Oil Corporation has been helping western America drive with confidence for over 80 years. Formed from the assets of eleven small petroleum companies in 1916, Sinclair is one of the oldest continuous names in the oil business. The first corporate emblem, SINCO, was registered November 1, 1916.

Sinclair began development of the apatosaurus (brontosaurus) in its advertising, sales promotions, and product labels in 1930. The apatosaurus was registered as a Sinclair trademark in 1932. An exhibit at the 1933 Chicago Worlds Fair highlighted dinosaurs and established Sinclair as the company that featured the apatosaurus. Again in 1964 at the New York City Worlds Fair, Sinclair proudly displayed an exhibit featuring nine life-sized dinosaurs highlighting its unique association with the age of the dinosaur--an age representative of the beginning of the formation of crude oil.

The current Sinclair trademark is one of the most recognized company emblems in the United States. The pentagon border and apatosaurus figure was registered in 1959.

Most oil companies have modified their corporate emblem while undergoing reorganization or ownership changes. Sinclair's trademark has remained unchanged. With the current popularity of dinosaurs in general, the Sinclair trademark and the sales promotion items using the apatosaurus are more popular than ever.
