Interesting Historical Facts
Pennzoil is an American oil company founded in Los Angeles, California in 1913. In 1955, it was acquired by Oil City, Pennsylvania company South Penn Oil, a former branch of Standard Oil. In 1963, South Penn Oil merged with Zapata Petroleum; the merged company took the Pennzoil name.
During the 1970s, the company moved its offices to Houston, Texas. In 1977 a spin-off company was formed called Pogo, which stood for Pennzoil Offshore Gas Operators.
Pennzoil was headquartered in Pennzoil Place in Downtown Houston during the 1970s. In 1998, the company merged with onetime rival Quaker State to form Pennzoil-Quaker State. In 2002, the Royal Dutch/Shell Group purchased Pennzoil-Quaker State to form SOPUS--Shell Oil Products US.
The following are products offered from Pennzoil:
Motor Oils - Pennzoil motor oil is the mainstay of the Pennzoil brand name. As of FY 2007 Pennzoil was the number one selling motor oil in the United States, competing with Castrol, Valvoline, and Havoline.

Jiffy Lube is a wholly owned subsidiary of Pennzoil-Quaker State Company and was purchased in 1990. The company's franchise outlets in the United States and Canada offer quick oil changes, chassis lubes and other automotive services.
Though not much emphasis has ever been placed on gasoline, Pennzoil does sell gas. In the early parts of the company's history, the gas stations were branded as Pennzip, though they were later changed to Pennzoil. For decades, Pennzoil gas stations were mostly marketed in western Pennsylvania, western New York, northern and eastern Ohio, and northern West Virginia.
