Use Compatibility Charts with Caution

By Walt Moore, Editor | March 24, 2017

Grease-compatibility charts typically base judgments on thickener behavior. Not all charts agree, nor do they consider the basic measurements of consistency and dropping point. ExxonMobil includes the following disclaimers with this chart.

This matrix is based on information commonly used in industry, providing a general assessment of grease compatibility based on structural stability of mixtures of different grease thickeners. Not addressed are potential additive-related incompatibilities or other performance features. Classification may differ for specific greases depending on composition and manufacturing process. Always recommended is to thoroughly remove and clean out old grease remaining in application prior to converting to a different grease.
