Hot Shot’s Secret TBN Booster Additive is an engine oil stabilizer designed to increase total base number (TBN) and viscosity by replenishing essential detergents. It neutralizes acidic conditions that can corrode the engine, providing extended protection and improved oil performance.

• Increases total base number (TBN) and viscosity of engine oil
• Replenishes detergents lost over time for better oil stability
• Neutralizes acidic conditions to prevent engine corrosion
• Extends oil change intervals and improves oil oxidation stability
• Contains 100% active ingredients of a CK-4 Additive Package
• Infused with Hot Shot’s Secret FR3 Friction Reducer for added wear protection
• Compatible with all diesel engines
• Recommended for use with oil analysis
• Caution: Do not overdose vehicles with a diesel particulate filter
• Note: Ensure overall oil level does not exceed the fill level when adding

Hot Shot’s Secret TBN Booster Additive is specially formulated to fortify and stabilize engine oil by increasing its total base number (TBN) and viscosity. Over time, detergents in oil are depleted, reducing the oil’s ability to neutralize harmful acidic conditions that can lead to engine corrosion. By replenishing these vital detergents, TBN Booster enhances the oil’s protective qualities, allowing for extended oil change intervals, improved viscosity stability, and reduced oil oxidation.

This concentrated additive contains 100% active ingredients, including a CK-4 additive package, TBN Booster, and Hot Shot’s Secret FR3 Friction Reducer, which improves lubrication and reduces engine wear. It is compatible with all diesel engines and is recommended to be used in conjunction with oil analysis to ensure optimal performance.

Caution: Do not overdose vehicles with a diesel particulate filter.
Note: Please ensure the overall oil level does not exceed the recommended fill level when adding TBN Booster Additive.
