The Oil City Oil & Grease Company was founded in 1908 by Charles Suhr and Daniel J. Cavanaugh in Oil City, Pennsylvania. It was a eastern distributor of "Pennzoil" products. In 1921, the company changed its name to the Pennzoil Company. In 1922, a third Pennzoil Company was established in Buffalo, New York. The firms obtained their motor and lubricating oils from the Penn American Refining Company.
In 1924, Penn-American merged with its three marketing companies: Pennzoil Company (California), Pennzoil Company (Pennsylvania), and the Pennzoil Company (New York) to form the Pennzoil Company. A year later, 51% of the firm was acquired by the South Penn Oil Company (gained full control in 1955). In 1963, it merged with the Zapata Petroleum Corporation and in 1968 with the United Gas Corporation. The company merged with the Quaker State Corporation in 1998. It was acquired by the Shell Oil Company in 2002.
