Lubricating Oil Composition comprising a hydrogenated imide derived from a Diels-Alder adduct of maleic anhydride and a furan

摘要

A crankcase lubricating oil composition for an internal combustion engine comprising (A) an oil of lubricating viscosity in a major amount; and, (B) as an additive component in a minor amount one or more, oil-soluble imides derived from a hydrogenated Diels-Alder adduct of a maleic anhydride and a furan, where the imide group has the formula NR, where R is an aliphatic hydrocarbyl group having 4 to 8 carbon atoms.
