Joe Gibbs Racing Oil BR

Used by Joe Gibbs Racing to break-in and dyno all their NASCAR Nextel Cup and Busch Series engines, this petroleum based oil provides superior break-in properties for flat-tappet engines. The special additive package promotes ring seal and provides maximum protection for cams and lifters during initial break-in. BR can also be used to break in roller cam engines, and it can be used as a general purpose dyno oil.
