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. In 1968 United Gas Corporation became part of Pennzoil. (Although United Gas was a larger company, pre-merger, Pennzoil had successfully used a "leveraged buyout" strategy.) 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 1999 Pennzoil's E&P business (known as PennzEnergy) was acquired by Oklahoma City-based Devon Energy and the [now known as] Pennzoil-Quaker was purchased by Royal Dutch/Shell Group to form SOPUSShell Oil Products US.

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.

In the 1990s, Pennzoil gas experienced a bit of a revival when Pittsburgh area convenience store chain Cogo's began co-branding themselves with Pennzoil. The co-branding lasted only a few years, and Cogo's switched brands to BP and Exxon in 2001.
