Abstract:

Disclosed is a method for improving copper corrosion performance of a lubricating oil composition containing (a) a major amount of a base oil of lubricating viscosity; and (b) one or more dispersants containing one or more basic nitrogen atoms. The method involves adding to the lubricating oil composition an effective amount of one or more copper corrosion performance improving agents containing one or more oil-soluble titanium compounds.
