PennGrade 1 - Official Motor Oil of the Indianapolis 500


High performance that only The Original Green Oil can deliver.

The demands the road, racing or just hard driving and camshafts to rings and pistons. Without the right protection, your car will lack efficiency, wear down faster, and underperform.

That’s why we recommend the motor oil endorsed for decades by racers, engine builders, and manufacturers: PennGrade1. It delivers excellent shock load and temperature protection to engine parts, while providing:

•Film strength/protection under demanding torque
•Anti-foaming, stability and high temperature protection
•Detergent/dispersant additives for engine cleanliness
•Oxidation and foam inhibitors to protect against thermal degradation, air entrainment

The result is reduced internal friction, strong anti-wear, and increased horsepower.

100 Percent Pure Pennsylvania-Grade Crude Oil

PennGrade1’s power comes from its base: 100 percent pure Pennsylvania-grade crude oil, long recognized as one of the best worldwide sources of high quality lubricant base stocks. Known for its green color and exceptional ability to cling to metal, this stock is tenacious. It minimizes wear when stressed, even during dry or cold starts.

It has a long history and track record of proven quality, still refined in Bradford Oil Field in Bradford, Pennsylvania, where it was first extracted in 1859. The refinery is the oldest continuously operating lube oil refinery in the United States.
