How to Determine Grease Compatibility and Why It’s Important
Grease compatibility charts have been developed and circulated since the 1980s without much alteration. However, grease technology has changed significantly over the years, and there are many proven examples of performance that contradict several widely used compatibility charts. Recent research shows grease compatibility charts to be contradictory and dated. Changing formulations and complexity in application have rendered grease compatibility charts unreliable. This paper describes the most common examples of incompatible mixing and how to determine if two greases are compatible.
