The Foundation For Maximum Durability and Performance
Driven Engine Break-In Oils are used to dyno and break-in all of the engines at Joe Gibbs Racing. This petroleum based oil has been formulated to supply the highest levels of zinc and phosphorus to the cam and lifters. No additional zinc (ZDDP) additives are required. Driven Engine Break-In Oils provide the maximum protection available during the critical engine break-in period. This oil is ideal for testing and power pulls on the dyno, one night of racing or up to 400 miles on the street!
