Pennzoil’s rich raceway heritage spans decades, from its first appearance in the early 1930s lubricating the engine of Indy 500 driver Russell Snowberger to its recent use in 2007 Daytona 500–winner Kevin Harvick’s car. Whether on the track in the Sprint Cup Series or in a garage in the suburbs, car owners who lube their rides with Pennzoil motor oil benefit from a more than 100-year lineage that dates back to one of John D. Rockefeller's original companies. The velvety substance contains trademarked Hyper Cleansing Technology and Active Cleansing Agents, which help to purify the engine's components and ward off damage caused by gasoline byproducts such as soot, carbon, varnish, and sulfuric and nitric acid. Pennzoil’s many service stations dot terra firma from the Atlantic to the Pacific and feature friendly technicians who perform oil changes and replace parts gone missing after the neighbor’s metal-detector-club meetings.
