A LUBRICATING GREASE COMPOSITION WHICH COMPRISES A LUBRICATING OIL THICKENED TO GREASE CONSISTENCY WITHIN THE RANGE OF 5 TO 40WT. PERCENT OF A COMPLEX OF A METAL SALT OF ACETIC ACID, A METAL SALT OF A MEDIUM MOLECULAR WEIGHT CARBOXYLIC ACID CONTAINING FROM ABOUT 3 TO 10 CARBON ATOMS, AND A METAL SOAP OF A HIGH MOLECULAR WEIGHT CARBOXYLIC ACID CONTAINING FROM ABOUT 12 TO 22 CARBON ATOMS, WHEREIN THE MOL RATIO OF ACETIC TO THE OTHER CARBOXYLIC ACIDS IS AT LEAST 4:1, THE MOL RATIO OF MEDIUM TO HIGH MOLECULAR WEIGHT ACIDS IS IN THE RANGE OF 0:5:1 TO 10:1 THE AVERAGE DIFFERENCE IN NUMBER OF CARBON ATOMS PER MOLECULE BETWEEN THE HIGH AND THE MEDIUM MOLECULAR WEIGHT CARBOXYLIC ACIDS IS AT LEAST 7, THE METAL CONSTITUENT OF SAID SOAPS AND SALTS IS SELECTED FROM THE GROUP CONSISTING OF ALKALINE EARTH METALS AND ZINC, AND SAID COMPLEX IS PREPARED AT A TEMPERATURE IN THE RANGE OF 400* TO 550*F.
