TBN Booster additive is the only fortified engine oil stabilizer that increases total base number (TBN) and viscosity by replenishing the detergents and dispersants that are naturally lost over time. When these detergent and dispersant additives are replenished, your oil will be able to effectively neutralize the acidic conditions that corrode your engine. TBN Booster additive is a concentrated formula that contains 100% active ingredients of a CK-4 Additive Package, a TBN Booster and the infusion of Hot Shot’s Secret FR3 FRICTION REDUCER.

CAUTION: Do not overdose vehicles with a diesel particulate filler.
