发明名称 Gear Oil Compositions, Methods of Making and Using Thereof
摘要 A gear oil composition is provided. The composition comprises an isomerized base oil having consecutive numbers of carbon atoms, less than 0.05 wt. % aromatics, a viscosity index between 150 and 170, Oxidator BN of 15 to 50 hours; and 0.001 to 30 wt % at least an additive selected from traction reducers, dispersants, viscosity modifiers, pour point depressants, antifoaming agents, antioxidants, rust inhibitors, metal passivators, extreme pressure agents, friction modifiers, and mixtures thereof. In one embodiment, composition displays a pressure viscosity coefficient of greater than 9.5 GPa-1 at 140° C. and a Timken OK load per D2782 (E2006) of at least 50 lbs.
