摘要
Provided is an internal combustion engine lubricating oil composition which comprises a major amount of an oil of lubricating viscosity; one or more oil soluble or oil dispersible organic acid anhydrides, said anhydride comprising at least one hydrocarbyl or hydrocarbylene moiety having from about 10 to about 400 carbon atoms; and an oil soluble or oil dispersible secondary hydrocarbylamine compound, a tertiary hydrocarbylamine compound, or combinations thereof. Also provided is a method for maintaining and/or increasing fresh oil TBN of a lubricating oil composition while at the same time improving seal performance in an internal combustion engine.
