FULL DESCRIPTION

Penn-Grade 1 30W Break-In Engine 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 film strength offer complete anti-wear, anti-scuffing protection for even the most demanding of applications such as those presented by break-in of engines with ‘flat tappet’ cams.
