Pennzoil is a United States-based motor oil brand currently owned by Shell plc. Established in 1913 in Pennsylvania, the company remained independent until Shell's acquisition in 2002, after which Pennzoil became an integral part of Shell's petroleum portfolio.
Origins and Growth
The roots of Pennzoil can be traced to the South Penn Oil Company, which was founded in 1889 in Oil City, Pennsylvania by businessmen Michael Late Benedum and Joe Trees as an affiliate of Standard Oil. Following the dissolution of Standard Oil in 1911, South Penn Oil operated independently and emerged as the leading oil producer in its region. By 1913, two separate entities—one based on the East Coast and the other on the West Coast—were marketing motor oils under the Pennzoil name. These refineries and distribution networks were consolidated into "The Pennzoil Company" in 1925.
In 1926, South Penn purchased a controlling interest of 51% in Pennzoil, which increased to 88% by 1955 when shareholders approved merging Pennzoil into South Penn Oil. The year 1963 saw South Penn merge with Zapata Petroleum and Stetco Petroleum, creating a new "Pennzoil Company" headquartered in Houston, led by president Hugh Liedtke. By 1965, Pennzoil had expanded its petroleum product sales to international markets.
A pivotal development occurred in 1968 when Pennzoil completed a leveraged buyout of United Gas Corporation, a company five times larger than itself. This transaction substantially enlarged Pennzoil’s asset base and prompted a name change to "Pennzoil United, Incorporated." During the 1970s, the company relocated its headquarters to Pennzoil Place in downtown Houston.
In 1977, Pennzoil established a spin-off entity named POGO (Pennzoil Offshore Gas Operators), dedicated to offshore gas ventures, thereby strengthening its position within energy production industries.
Pennzoil, Co. v. Texaco, Inc.
In 1984, Pennzoil entered into an informal yet enforceable agreement with Getty Oil to acquire a major portion of Getty’s oil holdings, securing rights to its oil reserves. Soon thereafter, Texaco attempted to purchase Getty outright, disrupting Pennzoil’s arrangement.
Pennzoil initiated litigation against Texaco in Texas state court for tortious interference, represented by attorneys Joe Jamail and Baine Kerr. The jury awarded Pennzoil $7.53 billion in compensatory damages plus $3 billion in punitive damages. Under Texas law, this verdict allowed Pennzoil to place liens on Texaco’s assets unless Texaco posted a bond covering the judgment amount.
Prior to enforcement of the judgment, Texaco filed suit in federal court alleging constitutional violations; both the district court and the Second Circuit ruled in favor of Texaco. However, upon appeal, the U.S. Supreme Court overturned those rulings and upheld the state court’s decision.
Texaco appealed the Texas judgment; while compensatory damages were affirmed by the Court of Appeals, punitive damages were reduced from $3 billion to $1 billion. As compensation for their legal efforts, Jamail and Kerr received $335 million and $10 million respectively from Pennzoil.
Following Texaco’s bankruptcy filing, both companies reached a settlement valued at $3 billion. This landmark litigation profoundly influenced Pennzoil’s financial trajectory and reputation within the industry.
Acquisition
In 1998, Pennzoil divested its motor oil and related segments, merging with competitor Quaker State Oil Production Corporation to establish the "Pennzoil-Quaker State Company." The following year, Oklahoma City-based Devon Energy acquired Pennzoil's exploration and production division, known as PennzEnergy. Concurrently, the Royal Dutch/Shell Group purchased the remaining operations, forming SOPUS Products (Shell Oil Products US).
By 2002, Shell Oil Company, the American subsidiary of Shell plc, took over Pennzoil-Quaker State. It continued marketing the products under two separate motor oil brands: Pennzoil and Quaker State.
Gasoline
While gasoline sales were never central to Pennzoil’s business strategy, the company retailed fuel mainly across western Pennsylvania, western New York, northern and eastern Ohio, and northern West Virginia. Initially, gas stations operated under the Pennzip name before transitioning to Pennzoil branding.
During the 1990s, the Pittsburgh-based convenience store chain Cogo’s co-branded with Pennzoil but switched affiliations to BP and Exxon by 2001. After Shell’s acquisition, some Pennzoil-branded stations—primarily in western Pennsylvania—considered adopting Shell branding but instead partnered with 7-Eleven starting in 2003. By 2006, BP replaced Pennzoil at multiple locations; others became independent or unbranded. By the mid-2010s, Pennzoil had withdrawn entirely from gasoline retail.
Commercial automotive and motorcycle partnerships
Pennzoil maintains official long-term lubricant partnerships with leading automakers including all Stellantis marques except for Peugeot, Citroën, DS Automobiles, Opel, and Vauxhall. Other key partners include BMW, Mini, Rolls-Royce, Hyundai, Genesis, and Chevrolet (in collaboration with Mobil 1 and Valvoline). Since Shell’s acquisition in 2002, it has also been partnered with Ferrari. In the US market, Pennzoil is an officially recommended motorcycle engine oil for both BMW Motorrad and Ducati.
Motorsports
Pennzoil has established a significant presence in motorsports by leveraging sponsorships to boost brand recognition and industry influence. Early endorsements included USAC National Championship racers such as Al Unser and Johnny Rutherford, with Rutherford capturing the 1980 Indianapolis 500 and championship under Pennzoil’s backing. From 1983 through 1990, Pennzoil supported Team Penske driver Rick Mears in the CART World Series, achieving wins at the Indianapolis 500 in both 1984 and 1988.
In Japan, Pennzoil sponsored Nismo in the All Japan Grand Touring Car Championship (JGTC) between 1998 and 2001, aiding in securing GT500 championships in 1998 and 1999. The brand also supported IndyCar driver Sam Hornish Jr. of Panther Racing from 2001 to 2003. More recently, since 2011 Pennzoil has maintained a part-time sponsorship with Team Penske’s Hélio Castroneves, particularly at the Indianapolis 500. The iconic yellow paint scheme—known as the "Yellow Submarine"—has become synonymous with Pennzoil’s racing identity.
In NASCAR, Pennzoil sponsored Steve Park of Dale Earnhardt, Inc. from 1998 to 2003 before backing Kevin Harvick of Richard Childress Racing between 2007 and 2010. Team Penske took over sponsorship duties in 2011 with drivers including Kurt Busch, then A. J. Allmendinger, and from 2013 onward, Joey Logano. Under Pennzoil’s banner, Logano won the Daytona 500 in 2015 as well as NASCAR Cup Series titles in 2018 and 2022. Since 2018, Pennzoil has been the title sponsor of NASCAR’s Las Vegas spring race—the Pennzoil 400—with Logano winning that event in both 2019 and 2020.
Expanding its motorsport involvement, Pennzoil sponsored the Grand Prix of Houston in 2013 and has served as official motor oil supplier for German-American GTLM competitor BMW Team Rahal Letterman Lanigan Racing since 2015. The company also supports American Formula One entrant Haas F1 Team starting from the 2016 season. In NHRA drag racing, it sponsors Don Schumacher Racing along with drivers Matt Hagan (Funny Car) and Leah Pruett (Top Fuel). Additionally, Pennzoil has supported prominent drivers such as Ken Block, strengthening its ties within motorsport culture.
Through its alliance with Shell, Pennzoil provides lubricants to Formula One powerhouse Scuderia Ferrari and MotoGP’s Ducati Team, reinforcing its global footprint and competitive edge in high-performance automotive sectors.
