This disclosure relates to a lubricating oil for an electric vehicle powertrain and powertrain components. The lubricating oil has a composition including a lubricating base oil as a major component, an additive package, as a minor component, and an effective amount of one or more conductivity agents, as a minor component. The lubricating oil has an electrical conductivity from about 10 pS/m to about 20,000 pS/m, a dielectric constant of about 1.6 to about 3.6, with a ratio of electrical conductivity-to-dielectric constant from about 5 to about 10,000. This disclosure also relates to methods for producing a lubricating oil for an electric vehicle powertrain and powertrain components. |
