The Total Base Number test tells you how much active additive is present in the oil.
Choose either a standalone TBN test, or add a TBN onto a standard oil analysis (Oil + TBN).

$25.00 – $50.00
Description
The Total Base Number test is based on ASTM D4739 and gives a measure of the amount of active additive present in the oil.
When an oil is new, the TBN level is directly related to the amount of detergent/dispersant additive (basically calcium and magnesium) that was added during the blending process. As an oil gets used, the TBN level will tend to drop.
This test is very similar to the TAN test, but an acid solution is added rather than a basic solution and once the mixture reaches a pH of 3.0, the test is complete.
Minimum amount of oil required: 10 ml
