Abstract:
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.

Claim (Index 1):
A method for improving low temperature performance of a lubricant in a compression-ignited internal combustion engine, the method comprising operating the engine with a lubricating oil composition comprising (a) greater than 50 wt. % of a base oil of lubricating viscosity; and (b) 0.1 to 40 wt. % of an overbased alkaline earth metal salt of an alkyl-substituted hydroxyaromatic compound, wherein the alkyl substituent is a residue derived from an isomerized alpha-olefin having from 12 to 40 carbon atoms per molecule; wherein the lubricating oil composition is a monograde lubricating oil composition meeting specifications for SAE J300 revised January 2015 requirements for a SAE 20, 30, 40, 50, or 60 monograde engine oil, and has a TBN of 5 to 200 mg KOH/g, as determined by ASTM D2896.
