Break-in & Assembly Oil

Used by Joe Gibbs Racing to break-in and dyno all their engines, this petroleum oil provides the highest levels of zinc and phosphorus for flat-tappet engines. The additive package promotes ring seal and provides maximum protection available for cams and lifters during initial break-in. Requires no additional additives. Viscosity typical of 15W-50.
