Patent ID: 8569215

Claim:
A push belt continuously variable transmission (CVT) oil composition comprising a base oil admixed with 2-8 wt % of a polymethacrylate viscosity control agent, 1-3 wt % of a succinimide dispersing agent, 0.5-1.5 wt % of a borated dispersing agent, 1.0-1.5 wt % of hyperalkaline borated calcium sulfonate, 0.5-1.0 wt % of hydrocarbylamine, 0.2-0.4 wt % of hyperalkaline magnesium hydrocarbylbenzenesulfonate, 0.3-0.5 wt % of calcium salicylate, and 0.2-0.4 wt % of alkyl phosphate phosphoric acid as friction control agent, 1.0-1.4 wt % of an antioxidant, 1.0-1.5 wt % of a diluent and 0.1-0.3 wt % of borated epoxide as an anti-wear agent, wherein the base oil is highly refined mineral oil or synthetic oil having a kinematic viscosity of 3-10 cSt at 100° C. and a viscosity index of at least 120.
