About Pennzoil: A Century of Engine Protection

Few names in automotive lubrication carry the weight of Pennzoil. Founded in 1913 in Pennsylvania, Pennzoil operated as an independent American company for nearly a century before being acquired by Shell plc in 2002. What started as a regional lubricant marketer grew into one of the most recognized motor oil brands on the planet, with a legacy shaped by innovation, competition, and relentless engineering progress.

Early in its history, the company sharpened its focus on producing high-quality lubricants, ultimately devising the Pennzoil brand name to represent that commitment to excellence. Over the following decades, Pennzoil became synonymous with engine care — racking up an impressive series of Indianapolis 500 racing records that cemented its reputation for performance under pressure.

PurePlus Technology: A Revolution in Synthetic Oil

The brand's most significant modern leap came after its acquisition by Shell. Shell brought a patented innovation to the Pennzoil brand: PurePlus Technology. Unlike traditional synthetic motor oils made from crude oil, Pennzoil's Platinum Full Synthetics are made from a specialized gas-to-liquid process, resulting in a 99.5% pure base oil for optimum performance. This technology underpins some of the most advanced motor oils available to everyday drivers and racing teams alike.

Pennzoil Engine Oil: Built for Every Engine, Every Driver

At the core of the Pennzoil lineup is its expansive range of engine oil products, designed to cover everything from aging high-mileage commuters to high-performance track vehicles. Pennzoil Ultra Platinum Full Synthetic keeps pistons up to 65% cleaner than required by the industry standard — a benchmark that speaks to the brand's engineering ambitions. For drivers who prefer a more budget-conscious option, Pennzoil's conventional oil formula helps keep engines clean and responsive until the next oil change.

The lineup is available in multiple viscosities, including popular options like 5W-20, 5W-30, and 0W-20 for different engine needs. Whether you drive a daily commuter, a truck, or an SUV, there is a Pennzoil formulation engineered specifically for your engine's demands.
