Abstract: The lubricant for a sump-lubricated, compression-ignited engine may contain an amount of a C12-C24 carboxylic acid-based fuel additive or component obtained by migration from the fuel. Good lubricant performance is obtained by including in the lubricant a boron-containing additive in an amount to provide about 2 to about 500 ppm B to the lubricant, provided that the total sulfated ash level is less than 0.8 weight percent.

Abstract: The present invention provides a nitrogen-free fuel detergent additive, fuel additive compositions containing the same, and fuel compositions containing the same, for use in internal combustion engines, where the additive is the reaction product of (i) hydrocarbyl phenol, cresol or similar material and (ii) a aldehyde, in the presence of an optional catalyst, wherein the additive provides acceptable engine deposit control that is comparable and/or better than the deposit control provided by nitrogen-containing fuel additives.

Abstract: A lubricating composition comprising an oil of lubricating viscosity, 1 to 1000 parts per million by weight of titanium in the form of an oil-soluble titanium-containing material, and at least one additional lubricant additive provides beneficial effects on properties such as deposit control, oxidation, and filterability in engine oils.

Abstract: The present invention provides an additive composition and a fuel composition for use in internal combustion engines, where the compositions comprise a friction modifier which is the condensation product of (i) certain carboxylic acids and (ii) a mixture comprising a branched alcohol or branched amine having 1 to about 150 carbon atoms, or combinations thereof wherein the fuel composition improves the fuel economy of the engine in which it is used and where the fuel additive composition has improved low temperature storage stability compared to compositions containing other fatty acid-derived friction modifiers.

Abstract: The present invention provides a fuel additive composition comprising (a) an alkoxylate detergent, (b) a fatty acid or derivative thereof, or mixtures thereof wherein the additive composition is soluble in the fuel where the fuel is a blend of hydrocarbonaceous and nonhydrocarbonaceous fuel with a nonhydrocarbonaceous fuel content of at least 50 percent by weight. Additionally, the present invention further provides for a fuel composition comprising such a additive composition and such a fuel. The present invention also provides for a method of operating an engine and a method of reducing deposits in a fuel system by using such an additive composition and fuel blend.
