    摘要： Provided is a lubricant blend including one or more lubricant base stocks and one or more dispersants. The dispersant is chosen from a polyalphaolefin succinimide, a polyalphaolefin succinamide, a polyalphaolefin acid ester, a polyalphaolefin oxazoline, a polyalphaolefin imidazoline, a polyalphaolefin succinamide imidazoline, and combinations thereof. The one or more dispersants are present at 2 to 20 wt % based on the total weight of the blend. The one or more dispersants and the one or more lubricant base stocks are together present at 8 wt % or more of the total weight of the blend. Provided is also a process for making the lubricant blend and a method for the service life of a lubricant.

    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.
