TBN Booster 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 is able to effectively neutralize the acidic conditions that corrode your engine. TBN Booster is a concentrated formula that contains 100% of the active ingredients in a CK-4 Additive Package, a TBN Booster and the infusion of Hot Shot’s Secret FR3 FRICTION REDUCER.
