Abstract:
1. A gear oil composition, comprising: a) a base oil comprising a mixture of at least an isomerized base oil having consecutive numbers of carbon atoms and less than 10 wt % naphthenic carbon by n-d-M and a mineral oil having a kinematic viscosity of 3 to 120 mm2/s at 100° C. and a viscosity index of at least 60, the isomerized base oil having a viscosity index greater than 28×Ln (Kinematic Viscosity at 100° C., in mm2/s)+300; b) 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;
