BR Break-In Oil

Used by Joe Gibbs Racing to break-in and dyno all their engines, this petroleum oil provides optimum 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. Does not require additional additives. Viscosity typical of 15W-50.

 

     

 

 

BR-30 Break-In Oil

The same high zinc and phosphorus formula as our original break-in oil, now in a SAE 5W-30 viscosity for tight clearance and/or low temperature break-in. Good for restrictor plate engines, drag race engines, and OEM rebuilds. Provides excellent ring sealing. Does not require additional additives. Good for full power pulls on the dyno, one night of racing or up to 400 miles on the street.

 

     

 

 

 

Assembly Grease
