Lubricating oil compositions for marine diesel engines

摘要

Lubricating oil compositions for residual fuel oil-fuelled diesel engines for 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 to ASTM D-2896 and a viscosity at 100 DEG C in the range from 9 to 30 mm<2>s<-1> as measured according to ASTM D-445. The lubricating oil compositions of the present invention demonstrate improved cylinder liner wear performance.
