Pennzoil has a long history of innovation, dating back to the early days of the automobile. The company was founded in 1913 by William C. Liedtke; His vision was to create high-quality motor oil that would protect engines from the build-up of sludge and other deposits. After a few years, two other parties joined in reestablishing the Pennzoil company.

Pennzoil’s first products were a line of lubricants for steam engines and railway cars. The company became popular quickly, and by the 1920s, Pennzoil was the leading motor oil brand in the United States. In 1956, Pennzoil made history again when it introduced the first motor oil made with synthetic ingredients. 

This new formulation provided better engine protection, and synthetic motor oils soon became the industry standard. They had a viscosity of 5W30. Some additives may also be present in these oils, which give them specific colors. The Pennzoil Company produces fully synthetic oils, racing oils, high mileage oils, conventional oils, and synthetic blend oils. 

Some of this company’s most common fully synthetic oils include Pennzoil Ultra Platinum, Pennzoil Platinum, and Pennzoil Platinum Euro. Similarly, Pennzoil Ultra Platinum Full Synthetic is a standard racing oil. If you consider high mileage oils, the famous product is Pennzoil Platinum High Mileage Synthetic Motor Oils.
