Brad Penn Brand
Brad PennŽ Penn Grade 1 Racing Oils are formulated using a unique base oil cut from their own Pennsylvania refinery. PA grade crude oil has exceptional film strength and unsurpassed metal 'wetting' abilities. We like the increased concentration of "zinc" (zinc dialkyldithiophosphate a/k/a ZDDP) which provides outstanding anti-wear/anti-scuffing protection for engines with 'flat tappet' or roller cams. Known as "The Green Oil," it's the oil racers and engine builders have all known and loved.
