IN THE ART OF LUBRICATION OF A CONTROLLED-SLIP DIFFERENTIAL WHICH HAS STARTED TO SLIP EXTENSIVELY DUE TO SUBSTANTIAL WEAR, THE IMPROVEMENT WHEREIN THE PREVIOUSLY USED LUBRICANT IS REPLACED BY A LUBRICANT CONSISTING ESSENTIALLY OF NON-HYDROCARBON ADDITIVES AND A HYDROCARBON BASE STOCK HAVING A KINEMATIC VISCOSITY AT 210*F. IN THE RANGE OF 1.5-200.0 CS. AND CONSISTING ESSENTIALLY OF A BLEND OF AT LEAST ONE C13-C29 NAPHTNENE AND FROM 0.1-20 PARTS BY WEIGHT, BASED ON SAID NAPHTHENE OF AT LEAST ONE MEMBER FROM AT LEAST ONE OF THE FOLLOWING GROUPS (A) AND (B): (A) A SYNTGETIC LIQUID C3-C8 OLEFIN HOMOPOLYMER; AND (B) A MEMBER FROM GROUP (A) ABOVE WHICH IS AT LEAST PARTIALLY HYDROGENATED; AND WHEREIN THE AMOUNT OF SAID BLEND WHICH IS PRESENT IN SAID BASE STOCK IS SUFFICIENT TO PROVIDE A GREATER COEFFICIENT OF TRACTION, MEASURED AT 600 FT./MIN., 200*F., 400,000 P.S.I., THAN WOULD BE PROVIDED BY SUBSTITUTION OF THE SAME AMOUNT OF ASTM OIL NO. 3 FOR SAID BLEND IN SAID BASE STOCK.
