Lubrication grease is a mixture of oil and soap or another thickener. The portion of the grease that determines the compatibility is the thickener. Lithium complex is the thickener that is most compatible with other thickeners. There are only a few other thickeners that are not compatible with lithium complex, when using one of the Graco greases.
