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 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.
- Gasoline – Pennzoil sells gasoline to motorists, mostly in western Pennsylvania.
- 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.
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 only lasted a few years, and Cogo's switched brands to BP and Exxon in 2001.
After Shell's purchase of Pennzoil, there was the possibility that the remaining Pennzoil stations—mostly in western PA—would be converted to Shell as part of the company's aggressive movement to expand nationally. This hasn't happened, but the three company-owned Pennzoil gas stations in the New Castle, Pennsylvania area began co-branding themselves with 7-Eleven in 2003, with more emphasis placed on the 7-Eleven brand name than Pennzoil itself.
As of June 2009, only one Pennzoil/7-Eleven combination remains, as another converted to BP in 2006 while retaining 7-Eleven (a Pennzoil in Ambridge, Pennsylvania also converted to BP at the same time). On June 8, 2009, the other Pennzoil/7-Eleven was sold to private owners and became an independent, unbranded location. There is also a surviving Pennzoil station in Ashtabula, Ohio right off of Ohio State Route 11.
Controversy arose in November 2003 following an investigation by NBC when it was discovered via the use of hidden camera that certain Jiffy Lube service stations were charging motorists for work they had in fact not performed. 5 out of 9 shops did not do the work that was told to customers.
Texaco, Inc. v. Pennzoil, Co.
Pennzoil filed a lawsuit that turned out to be a landmark. At first it was adjudicated by Judge Anthony J.P. Farris; it was finished by visiting Judge Solomon (Sol) Casseb of San Antonio. Pennzoil, represented by Joe Jamail and Baine Kerr, won $10.53 billion from Texaco, represented by Dick Miller.
The case was appealed. The decision of the trial court was upheld on condition that Pennzoil file a remittitur agreeing to a reduction of punitive damages from $3 billion, to $1 billion. Compensatory damages of $7.53 billion remained unaffected. Pennzoil paid Mr. Jamail $335 million and Mr. Kerr $10 million for the victory.
After Texaco filed for bankruptcy, Pennzoil agreed to settle the case for $3 billion 
Pennzoil Company, also called (1889–1963) South Penn Oil Co. or (1968–72) Pennzoil United, Inc. , American petroleum corporation that became an important producer of crude oil and natural gas and a major marketer of automotive products before disappearing at the end of the 20th century in a series of mergers and acquisitions.
Pennzoil’s origins can be traced to two parallel oil ventures that took place in Pennsylvania in the late 19th century. One of them, the South Penn Oil Company, was founded on May 27, 1889, as an oil-producing unit of the Standard Oil Trust, which at that time owned refineries and distribution networks but no producing oil wells. As part of Standard Oil, the South Penn Oil Company, headquartered in Oil City, Pennsylvania, expanded to become the largest oil producer in the Appalachian region. It became an independent company in 1911 when the Standard Oil Trust was dissolved.
In a parallel development, two related distributors of lubricating oils, one on the East Coast and the other on the West Coast, were founded in 1908 and 1913, respectively. Both companies bought their motor oil, which in 1916 they agreed to market as Pennzoil, from refineries that had operated near Oil City since the 1880s. Through a complex of mergers, the refiners and the growing number of Pennzoil distributors were incorporated in 1925 under the name the Pennzoil Company. That same year South Penn Oil acquired a controlling interest in Pennzoil, and operations became nationwide, from New York to California. More acquisitions followed over the years, and in 1955 South Penn Oil acquired complete ownership of Pennzoil. The company produced a range of products, though its principal products were Pennzoil-brand motor oils, and its reserves were mainly located in the older oil fields of the Northeast.
