Brad Penn PENN-GRADE 1 Break-In Oil
Formulated specifically to meet the critical lubrication needs of new engines during break-in while allowing proper seating of rings and component 'run-in'. Enhanced levels of "zinc" (zinc dialkyl dithiophosphate a.k.a. ZDDP) and superior oil fulm strength offer complete anti-wear, anti-scuffing protection for even the most demandign of applications such as those presented by break-in of engines with 'flat tappet' cams.
