When you start to use a new grease in an application, it is important to know whether the new and the old grease are compatible. This depends on whether the thickener and/or the base oil can mix with each other. A number of things can happen when two different greases are mixed:

• Nothing, i.e. the two greases are miscible

• The grease mix hardens, which can be devastating in, say, a central lubrication system

• The grease mix softens. The soap structure is broken down and the greases are not miscible. This can cause leakage and bearing failure

• We can help with miscibility tests ahead of product changes to avoid problems in advance. Feel free to contact us if you need help.

Thickeners - miscibility

+ = Compatible |  o = Miscibility test required |  - = Not compatible

The above table is based on the type of thickeners only. Please note that different types of additive may affect miscibility.
