摘要： A process for preparing a low ash detergent is described. The process involves mixing a surfactant composition that includes a hydroxybenzoate, sulfonate, or phosphonate detergent with an ashless nitrogen-containing compound to boost the base number of the hydroxybenzoate, sulfonate or phosphonate detergent.

摘要： A method for improving low temperature performance of a lubricant in a compression-ignited internal combustion engine is disclosed. The method comprises operating the engine with a monograde lubricating oil composition comprising (a) a major amount of a base oil of lubricating viscosity; and (b) a minor amount of an overbased alkaline earth metal salt of an alkyl-substituted hydroxyaromatic compound, the alkyl substituent being a residue derived from an isomerized alpha-olefin having from 12 to 40 carbon atoms per molecule.
