Abstract
A grease composition having improved load-carrying capability is disclosed. More specifically, the load-carrying capability of a grease is increased when a polyhydric alcohol having at least three hydroxy groups and at least two metal hydrocarbylthiophosphate compounds in which the metal is different in at least two compounds are incorporated into said grease. Glycerol is a preferred polyhydric alcohol while antimony dialkyldithiosphosphate and zinc dialkyldithiophosphate are preferred hydrocarbylthiophosphate compounds.
