Brad Penn ''Penn-Grade 1'' High Performance Oils are composed using unique base cut "Green Oil" stocks from Bradford, Pennsylvania with select additives to meet the stringent lubrication demands of highly stressed street and racing engines. The benefits of this special formulation are minimized wear, excellent shock load and high-temperature protection for bearings, rings, and pistons. Brad Penn ''Penn-Grade 1'' High Performance Oils have also been tested by many premier camshaft suppliers. The results of the testing have proven that this oil reduces internal friction for increased horsepower while maintaining outstanding lubricating protection for flat tappet and roller cams even under extreme conditions. The additive package in Brad Penn ''Penn-Grade 1'' High Performance Oils feature increased levels of ZDDP (zinc dialkyldithiophosphate) that provide excellent anti-wear protection. Anti-foam agents are employed to reduce foaming and air entrainment produced from crankcase windage. This oil also uses highly effective detergents, anti-oxidants and dispersants to offer thermal and oxidative breakdown protection by reducing varnish and deposit formation.
