Grease compositions comprising (1) a lithium soap derived from a fatty acid containing an epoxy group and/or ethylenic unsaturation, and (2) a dilithium soap derived from a straight chain dicarboxylic acid.

Greases comprising lithium salts derived from an epoxy substituted fatty acid in combination with other lithium salts and derived from an ethylenically unsaturated fatty acid, a dicarboxylic acid and a hydroxy-substituted aromatic acid are particularly effective.
