The methods relate to controlling at least one of oxidation, deposit formation and corrosion over the service lifetime of the oil. 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 10 pS/m to 20,000 pS/m, a dielectric constant of 1.6 to 3.6, with a ratio of electrical conductivity -to-dielectric constant from 5 to 10,000.
