Hot Shots Secret HSSTBN16Z TBN Booster Fortified Engine Oil Stabilizer 16 oz

The Hot Shot's Secret TBN Booster (HSSTBN16Z) is a fortified engine oil stabilizer engineered to restore and maintain the protective chemistry of engine oil as it ages. As engine oil is used, it naturally loses the detergents and dispersants that control contaminants and neutralize acids — causing the oil's Total Base Number (TBN) to drop and allowing acidity to increase. TBN Booster directly addresses this degradation by replenishing those critical additives, helping protect internal engine components over time.

Key Features:

• Increases engine oil's Total Base Number (TBN) by up to 7 points
• Replenishes lost detergents and dispersants to restore oil stability
• Neutralizes acidic conditions that lead to engine corrosion
• Slows oil oxidation rate and improves viscosity stability
• Supports extended oil drain intervals and reduced service frequency
• Contains 100% active ingredients of a CK-4 Additive Package plus a TBN Booster concentrate
• Infused with Hot Shot's Secret FR3 Nano Lubricant Technology for improved lubricity and reduced internal friction
• Compatible with conventional and synthetic engine oils, including Hot Shot's Secret Diamond Series Engine Oils

TBN Booster is a concentrated formula — the more you use within recommended treat rates, the more effectively it neutralizes acidic qualities and slows oxidation. Treatment rate varies based on desired TBN increase, initial TBN level, and engine oil capacity. Oil analysis is recommended to determine optimal treat rates and intervals.

Caution: Do not overdose in vehicles equipped with a diesel particulate filter (DPF). This 16 fl oz bottle is ideal for individual vehicle use and targeted TBN maintenance between oil changes.
