LUBRICATING OIL COMPOSITIONS

摘要

Lubricating oil compositions for residual fuel oil-fuelled diesel engines fo r marine and stationary applications comprising, or made by admixing: (a) a basestock of lubricating viscosity, in a major amount; and (b) an oil-soluble or oil-dispersible molybdenum compound, in a minor amount ; wherein the oil composition has a TBN from 20 to 100 as measured according t o ASTM D-2896 and a viscosity at 100.degree.C in the range from 9 to 30 mm2s-1 as measured according to ASTM D-445. The lubricating oil compositions of the present invention demonstrate improved cylinder liner wear performance.
