Grease is rather complicated compared to conventional lubricating system’s condition monitoring systems. You might ask, why bother? Really, it comes down to cost. Grease is generally more expensive than the equivalent lubricant, sometimes by a factor of 10 or more. In addition, a large number of grease systems are designed to last much longer periods between re-greasing compared to some conventional oil lubrication systems. As a result there is a real financial gain to be found from obtaining effective maintenance reliability recommendations.

The final step of conventional condition monitoring and equipment maintenance is normally testing of the fluid. A number of conventional grease tests, are designed to qualify grease manufacture. These tests, such as penetration and dropping point, may not give any significant information for reliability purposes. This may seem of great concern to most, but in-service grease testing is an area where most current research is focuses on.
