Lubricant is a vital element in the machinery system, to separate contact surfaces. Lubricant has purpose, such as: minimize the friction losses, absorb the heat from the surface of material and to transport the contaminant. foam cause lack of film lubricant on the contact surface. This phenomenon increase friction losses. The manufacturing and the testing of a test apparatus adopted ISO 6247, to simulate the real operating condition in machinery. Four samples of testing lubricant, eg: 2 of diesel motor lubricants and 2 gasoline motor lubricants are tested. <br /> <br /> <br /> The testing rig which has been manufactured and tested based on ISO 6247 can distinguish the foaming character of new and used lubricant. The used lubricant has a tendency to generate foam more than new lubricant, which can be seen in testing result. The ISO 6247 standard cannot be used to monitor the airoil dispersed of dark colour lubricant.
