Pennzoil is an American motor oil brand currently owned by Shell plc. The former Pennzoil Company had been established in 1913 in Pennsylvania, being active in business as an independent firm until it was acquired by Shell in 2002, becoming a brand of the conglomerate.[1]
History
Beginning and expansion
Origins of the company can be traced to the South Penn Oil Company, an oil business started in Oil City, Pennsylvania by Michael Late Benedum and Joe Trees in May 1889 as a unit of Standard Oil.[2] It became the largest oil producer in the region, becoming independent when Standard Oil was split in 1911. By those times, two companies, one on the East Coast and another on the West (founded in 1908 and 1913, respectively) started to market their motor oils under the brand Pennzoil. Their refineries and distributors were later incorporated as "The Pennzoil Company" in 1925.
