No, Gulf Gas is not owned by Chevron. Gulf Oil International Ltd., or simply known as Gulf Oil, is a British-based international brand of gasoline and lubricants owned by the Hinduja Group. The company was founded in 1901 in Pittsburgh, Pennsylvania when William Larimer Mellon purchased the J.M. Guffey Petroleum Company - later renamed to Gulf Oil Corporation - which would become an industry leader over its century-long history until it merged with Chevron in 1985. After being acquired by Chevron, the majority of what remained of the former business was rebranded under Chevron's own name while some independent service stations that were still operating under the Gulf brand maintained their presence until undergoing eventual conversion into other companies’ brands such as Shell and BP during subsequent years.
