Multipurpose complex calcium (cCa) greases are replacing Ca, Na, and Li greases. No study has been made of the effects of mixing such greases during the replacement procedure. The following properties were therefore evaluated for the greases and grease mixtures: yield stress, viscosity, heat-hardening, colloidal and mechanical stability, dropping point, lubricity, and water washout characteristics. Some of the results include: a decrease of the dropping point of the mixture, changes in yield stress in shear, in colloidal stability, and in mechanical stability in proportion to the mixture composition.
