Calcium sulfonate is the most widely used Lubricant detergent. Most calcium sulfonate detergents have a Base Number, commonly referred to as a Total Base Number (TBN), which indicates the ability to neutralize acid. So we also call sulfonate detergent TBN Booster.
By TBN, Sulfonate Detergents can be divided into Neutral or Low Base Number Sulfonates, Medium Base Number Sulfonates, High Base Number Sulfonates, and Super High Base Number Sulfonates.
What is a (Total Base Number) TBN booster?
TBN Booster is an engine oil additive that increases the Total Base Number, it increases the base reserve to neutralize the acids generated from the engine oil and fuel. It prevents acid corrosion to metal parts in the engine.
Why is (Total Base Number) TBN important in lube oil?
The Total Base Number (TBN) is an indicator to measure the content of the effective additives in lubricating oil, indicating the detergency and acid-neutralizing ability of the engine oil.
The TBN indirectly indicates the level of detergent and dispersant additives in the engine oil. Therefore, the TBN is an important quality indicator of Internal Combustion Engine (ICE) oil. In an engine, the decrease of TBN reflects the consumption of additives in the lube oil. Generally, when the TBN wears out, it is time to change the engine oil.
Most fuel contains sulfur, after burning, acidic substances will remain in the engine, which causes acid corrosion to the engine. The alkaline from the TBN booster can neutralize the acidic substances, so the TBN prevents acidic substances from corroding the engine.
