    Test Oil

    A lubricant with a tendency to foam can cause issues for both the machine and the lubricant itself. Foam can lead to micro dieseling and the production of soot, as well as poor machine performance, lubricant loss, and cavitation. Foam will also reduce the life of your lubricant by exposing the oil to more air. Air accelerates oxidation and degradation. Test Oil uses ASTM D892 to measure the foaming tendency of a lubricant. 200 ml of sample is placed into a graduated cylinder that is in a controlled-temperature bath. Compressed air is pressed through a diffuser stem and then through the sample. The volume of foam is measured after five minutes. Once the blowing has stopped, the time of the total foam dispersion is recorded. All foam should be dispersed by 250 seconds.
