Penn Grade 1 Racing Oil
When engine protection matters most, racers and performance enthusiasts have trusted Penn Grade 1® Racing Oil for decades. Descended from the legendary "Green Oil" formula, Penn Grade 1 is engineered specifically for high-performance street and racing engines that operate under extreme heat, load, and RPM conditions.
Formulated with premium base oils and a performance-focused additive package, Penn Grade 1 delivers exceptional film strength and wear protection where it matters most. Its elevated zinc and phosphorus (ZDDP) content helps protect camshafts, lifters, bearings, and valvetrain components from the increased stress associated with aggressive cam profiles, high spring pressures, and sustained high-RPM operation.
Whether you're competing at the drag strip, carving corners on a road course, running laps at your local oval, or maintaining a high-horsepower street machine, Penn Grade 1 Racing Oil provides the protection and reliability needed to keep your engine performing at its best.
