Olefin/maleic anhydride copolymer heterocyclic-azoles as antiwear additives, and fuel compositions

摘要

A fuel composition contains an antiwear additive comprising the reaction product of heterocyclic compound having antiwear activity such as a triazole e.g. benzotriazole, tolyltriazole, and a copolymer with succinic anhydride moiety, such as an olefin/maleic anhydride copolymer.
