    摘要: A multigrade crankcase lubricating oil composition comprising a mineral oil-based basestock of lubricating viscosity in a major amount and a non-hydrogenated olefin polymer in a minor amount. The lubricating oil composition also comprises a dispersant, a metal detergent, one or more other additives, and a viscosity modifier.

    摘要: A lubricating oil composition comprising, or made by mixing, a major amount of an oil of lubricating viscosity and a minor amount of at least one compound comprising a polynuclear molybdenum core having bonded thereto one or more monoanionic ligands capable of rendering the compound oil-soluble or oil-dispersible, and further comprising at least one ionic species that is not required to confer oil-solubility or oil-dispersibility to the compound, wherein the combination of said one or more monoanionic ligands and said at least one ionic species confers electrical neutrality to the compound and wherein the ratio of the number of molybdenum atoms in the core to the number of said ligands is greater than 1:1.

    摘要: A boron-containing dispersant composition containing one or more dispersants that are the reaction product of a polyalkenyl-substituted mono- or dicarboxylic acid, anhydride or ester; and a polyamine, in which at least one of the dispersants has a polyalkenyl moiety with a number average molecular weight of at least about 1800, and from greater than about 1.3 to about 1.7 mono- or di-carboxylic acid producing moieties per polyalkenyl moiety; and in which a ratio of wt. % of boron to wt. % of nitrogen (B/N) for the dispersant composition is from about 0.05 to about 0.24.
