BRAD PENN® PENN-GRADE 1®
Partial Synthetic SAE 20W-50 Racing Oil
Designed to offer higher performance racing engines the cold temperature operational benefits of an SAE `20W' engine oil while providing the desired film strength; sealing abilities; bearing, crankshaft, piston ring and valvetrain component anti-wear protection of an SAE 50 weight oil at normal engine operating temperatures.
The Brad Penn® Penn Grade 1® Racing Oils contain the higher level of anti-wear (ZDDP - zinc dialkyldithiophosphate) and enhanced film strength so critical to proper high performance engine protection. The Penn-Grade 1® oils "typical" 1,500 ppm Zinc (Zn) and 1340-1400 ppm Phosphorus (P) content provide the needed anti-wear protection to critical engine parts, such as piston/cylinder walls, roller cams under heavy valve spring pressure and especially those that employ a solid "flat tappet" type system. As important as the chemistry is to the Penn-Grade 1® oils, it is by no means the whole story. The unique base oil cut used to refine the Penn-Grade 1® Racing Oils maintain a tremendous affinity to metal surfaces. This naturally occurring "metal wetting" characteristic enables the oil to stay put on your highly stressed engines and makes the Penn-Grade 1® Racing Oil resist slinging for an extended period of time. Also, rest assured in knowing that the Penn-Grade 1® Racing Oils are 100% Made in the USA.
