Abstract: A quaternary ammonium salt detergent made from the reaction product of the reaction of: (a) a hydrocarbyl substituted acylating agent and a compound having an oxygen or nitrogen atom capable of condensing with said acylating agent and further having a tertiary amino group; and (b) a quaternizing agent suitable for converting the tertiary amino group to a quaternary nitrogen and the use of such quaternary ammonium salt detergents in a fuel composition to reduce intake valve deposits.

Abstract: The invention relates to lubricating compositions, processes of making such lubricating compositions, and method of using such lubricating compositions. The lubricating compositions of the present invention include a dispersant comprising a quaternary ammonium salt, a phosphorus-containing compound, a metal dialkyldithiophosphate, a derivative of a hydroxyl carbonyl compound and an amine and/or an alcohol. These compositions provide balanced deposit control and wear performance without causing any seal compatibility issues.

Abstract: Oxidative degradation may be reduced in a lubricant composition which contains an oil of lubricating viscosity and at least about 1 percent by weight of a C1-C3 alkyl ester of a carboxylic acid of about 12 to about 24 carbon atoms, by including within the lubricant composition a sulfonate detergent in an amount sufficient to provide at least about 0.2 percent by weight sulfonate soap to the lubricant composition, wherein the weight ratio of sulfonate soap to phenate soap in the lubricant composition is at least about 0.35:1.

IPC: C10M129/78

Abstract: The invention provides a lubricating composition containing (a) an oil of lubricating viscosity, (b) a phosphite having at least one hydrocarbyl group that has 4 or more carbon atoms, and (c) a compound derived from a hydroxy-carboxylic acid. The invention further relates to the use of the lubricating composition in an internal combustion engine.

Abstract: The disclosed invention relates to a composition comprising a grafted polymer. The polymer backbone comprises an olefin block and a vinyl aromatic block. The polymer backbone is grafted with a pendant carbonyl containing group, the grafting being conducted in oil in the presence of an initiator. The carbonyl containing-group is optionally substituted to provide ester, imide and/or amide functionality. The grafted polymer is useful as a dispersant viscosity modifier in lubricating compositions such as engine oils.
