Abstract: The present invention is directed to a method for controlling soot induced viscosity increase in diesel engines, by using as the diesel engine lubricant an oil formulation comprising a base oil containing about 10 to 80 wt % GTL base stock and/or base oil and/or hydrodewaxed or hydroisomerized/catalytic (or solvent) dewaxed base stock and/or base oil in combination with 20 to 90 wt % conventional Group I petroleum derived base oil, said base oil being further combined with a polymeric viscosity modifier, and to the lubricating oil which effects such control over soot induced viscosity increase.

Abstract: A method for preventing or reducing engine knock or pre-ignition in an engine lubricated with a lubricating oil by using as the lubricating oil a formulated oil. The formulated oil has a composition comprising at least one ester of a non-aromatic dicarboxylic acid. The at least one ester of a non-aromatic dicarboxylic acid preferably comprises at least one adipate ester (e.g., dialkyl adipate ester). A lubricating engine oil having a composition comprising at least one ester of a non-aromatic dicarboxylic acid (e.g., adipate ester). A fuel additive composition for use in a gasoline fuel composition or a diesel fuel composition. The gasoline fuel composition or the diesel fuel composition is used in a spark ignition internal combustion engine. The fuel additive composition comprises at least one ester of a non-aromatic dicarboxylic acid (e.g., adipate ester). The lubricating oils of this disclosure are particularly advantageous as passenger vehicle engine oil products.
