Abstract

A lubricating oil composition is described which is useful in internal combustion engines and which exhibit improved oxidation and wear performance. More particularly, lubricating oil compositions are described which comprise (A) a major amount of oil of lubricating viscosity; (B) at least about 1.0 % by weight of at least one carboxylic derivative composition produced by reacting (B-1) at least one substituted succinic acylating agent with (B-2) at least one amine compound characterized by the presence within its structure of at least one HN< group wherein said substituted succinic acylating agents consist of substituent groups and succinic groups wherein the substituent groups are derived from polyalkene, said polyalkene being characterized by an Mn value of 1300 to about 5000 and an Mw/Mn value of about 1.5 to about 4.5, said acylating agents being characterized by the presence within their structure of an average of at least 1.3 succinic groups for each equivalent weight of substituent groups; and (c) at least one manganese compound in an amount sufficient to provide from 1 to about 500 ppm of manganese as metal, provided that the manganese compound is not a neutral manganese dihydrocarbyl phosphorodithioate. The oil compositions also may contain other desirable additives including (D) at least one metal dihydrocarbyl phosphorodithioate ; (E) detergent effective amounts of at least one neutral or basic alkali metal salt of a sulfonic or carboxylic acid; and/or (F) at least one carboxylic ester derivative is defined herein. In one embodiment, the oil compositions of the present invention contain the above additives and other additives described in the specification in an amount sufficient to enable the oil to meet all the performance requirements of the API Service Classification identified as "SG".
