Abstract
An electric motor lubricating fluid for an electric motor system including a lubricating base oil, at least one sulfurized component, at least two phosphorus-providing additives, and at least one high molecular weight dispersant. The electric motor lubricating fluid provides acceptable wear performance as well as good electrical conductivity and oxidative stability for use in electric motor system fluids having a low viscosity.
