Abstract: An improved method of lubrication of a controlledslip differential comprises using a lubricant comprising a static friction reducing amount of an aliphatic phosphate ester and a hydrocarbon base stock having a kinematic viscosity at 210*F. in the range of 1.5-200.0 c.s. and containing a major amount of a hydrogenated polymer of C3-C12 olefin, such as a ''''true'''' isobutylene oligomer or of a blend of at least one C13-C29 naphthene 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), (b), (c) and (d): A. A SYNTHETIC LIQUID C3-C8 olefin homopolymer copolymer, or terpolymer; B. A MEMBER FROM GROUP (A) ABOVE WHICH IS AT LEAST PARTIALLY HYDROGENATED; C. A SEVERELY HYDROREFINED NAPHTHENIC LUBE CONTAINING LESS THAN 1% OF GEL AROMATIC HYDROCARBONS; AND D. A SEVERELY HYDROREFINED PARAFFINIC LUBE CONTAINING LESS THAN 1% OF GEL AROMATIC HYDROCARBONS; 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. The preferred lubricant also contains an extreme pressure additive (e.g. tricresyl phosphate).
