Summary:An automotive lubricating oil composition containing: (A) an oil of lubricating viscosity in a major amount; and (B) as an additive component in a minor amount, an oil-soluble or oil-dispersible 4-oxobutanoic acid having the moiety -CO(CH2)COOH bonded to (i) a group OR1 where R1 is hydrocarbyl group having 10 to 30 carbon atoms; or (ii) a group X being an aromatic group substituted with at least one hydrocarbyl group having 10 to 30 carbon atoms; or (iii) a group NR2R3 where one or both of R2 and R3 is hydrocarbyl group having from 10 to 30 carbon atoms and one but not both of R2 and R3 may be a hydrogen atom, or a salt thereof.
