Red Giant Oil Company LLC

About Us

Red Giant Oil began doing business in 1910 selling oil and other products to farmers and farm equipment dealers in the Midwest and eventually became incorporated in 1946. Fred Galvani, who had been a salesman for the company, purchased Red Giant Oil Company in 1959. Five years later, he purchased Searle Petroleum Company from the Harry Searle family, which had owned and operated that lubrication business since 1889. In the mid 1980’s, Red Giant Oil/Searle Petroleum Company began selling railroad engine oil and is now one of the largest suppliers of locomotive engine oil in North America.

On August 1st, 2018, HollyFrontier Corporation, headquartered in Dallas, Texas, purchased Red Giant Oil. At that time, the company’s name officially changed to Red Giant Oil Company LLC. HollyFrontier Corporation is an independent petroleum refiner and marketer that produces high value light products such as gasoline, diesel fuel, jet fuel and other specialty products.
