Signature Series Cleans Up The Competition

In the Total Base Number (TBN) Test, AMSOIL Signature Series 5W-30 Synthetic Motor Oil demonstrated the highest TBN of all oils tested, proving it helps keep engines cleaner, longer.

In general, the higher an oil’s TBN, the better its ability to neutralize contaminants such as combustion by-products and acidic materials. Higher TBN oils neutralize a greater amount of acidic material, which results in longer oil life and cleaner engines.

TBN levels decrease as the oil remains in service. When the level reaches a point where it can no longer protect against corrosion, the oil must be changed.

The TBN Test

AMSOIL Signature Series 5W-30 Synthetic Motor Oil

The Total Base Number Test (ASTM D2896) uses a series of chemical reactions to measure the alkaline additives in a motor oil. We recognize the value of formulating motor oils with high TBN, and AMSOIL Signature Series Synthetic Motor Oil features the highest TBN of the oils tested.

The AMSOIL Advantage

Targeted Application - Gasoline motor oils typically have lower TBN than diesel oils, which must contend with high contaminant loading from soot and sulfur

AMSOIL synthetic lubricants feature a large dose of quality additives that consistently deliver high TBN for the life of the oil. They neutralize acidic contaminants and keep them in suspension to maximize engine protection, AMSOIL lubricants use detergent and dispersant additives to significantly reduce sludge and carbon deposit formation. In the Total Base Number Test (ASTM 02896), AMSOIL Signature Series 5W-30 Synthetic Motor Oil demonstrated the highest TBN of the oils featured in the test, helping it deliver reliable protection for extended drain intervals.
