  • Publication number: 20100317552
    Abstract: A lubricant composition, lubricant concentrate and method for reducing engine deposits. The composition and method include a base oil of lubricating viscosity; an organo-molybdenum compound; a deposition reducing amount of a reaction product of an alkyl-substituted dicarboxylic acid compound selected from the group consisting of alkyl-substituted dicarboxylic acids, alkyl-substituted dicarboxylic acid anhydrides, and mixtures thereof, and a basic salt of aminoguanidine, in an amount sufficient to provide a product rich in alkyl bis-3-amino-1,2,4-triazole; and optionally a phenate detergent. The lubricant composition and method provide engine deposits that are less than an amount of engine deposits in the absence of component (c) and/or optional component (d).
