Description

Get a TAN with your standard analysis to find out the oil’s acidity level. A TAN is typically run on transmission and industrial-type samples.

The TAN measures how acidic the oil has become. Surprisingly, not all TANs start out at 0.0. It can be helpful to know an oil’s acidity level to start with (in its virgin state) when you’re trying to determine how acidic an oil has become from use.
