Abstract: ABSTRACT The invention is directed to a method for reducing low speed pre-ignition events in a spark-ignited direct injection internal combustion engine by supplying to the sump a lubricant composition which contains an oil of lubricating viscosity and a metal overbased detergent. The metal overbased detergent may be selected from sulfonate detergents, phenate detergents, and salicylate detergents, especially sulfonate detergents with a metal ratio of at least 5.

Abstract: The instant disclosure relates to hydrocarbyl- (e.g., alkyl-) benzene sulfonate detergents and their salts, where the hydrocarbyl group includes moieties equivalent to 5 to 10 carbon branched polyene compounds. Such compounds and their salts are useful as lubricant additives. The detergents disclosed herein may solve at least one problem of providing anti-wear performance, frictional performance, oxidation performance, viscosity performance, and detergency.

Abstract: The disclosed technology relates to lubricants for compression ignition internal combustion engines, particularly those demonstrating at least one of improved seals performance, reduced deposit formation, and excellent durability. The present invention provides a low zinc lubricating composition comprising (a) an oil of lubricating viscosity, (b) a borated dispersant, and (c) a metal-free organo-phosphorus anti-wear additive, wherein the lubricating composition is substantially free of a metal containing sulfur coupled alkyl phenol compound. Further, the low zinc lubricating composition contains zinc in an amount less than 600 ppm by weight of the composition.

Abstract: The disclosed technology relates to a dispersant composition comprising the reaction product of a polyolefin acylating agent and a polyamine having a sterically hindered head group. In addition, the technology relates to lubricating compositions containing the dispersant composition and an oil of lubricating viscosity, as well as methods of employing the lubricating composition in an engine and engine oils. Lubricating oils containing the dispersants of the disclosed technology simultaneously achieves seal compatibility, wear, deposit, varnish and corrosion control while also maintaining fuel economy performance over a broad temperature range.

Abstract: The invention is directed to a method for reducing low speed pre-ignition events in a spark-ignited direct injection internal combustion engine by supplying to the sump a lubricant composition which contains an oil of lubricating viscosity and a boron-containing ashless dispersant. The ashless dispersant may be selected from succinimide compounds prepared from aliphatic or aromatic amines.
