ABSTRACT:
The invention provides a method of lubricating a marine diesel engine, comprising supplying to said engine a marine diesel cylinder lubricant composition at a feed rate of 0.3 to less than 1.2 g/kW hr, wherein said lubricant composition has a ratio of /Σ(wt % overbased detergent)/Σ(wt % of boron from antiwear additives+wt % of phosphorus-containing antiwear additives) of greater than 12.5. The invention further provides a method capable of imparting improved cleanliness and decreased cylinder wear; and reduced deposits.
