    摘要: 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.

    摘要: A lubricating composition comprising: (a) a 2 mm2/s to about 12 mm2/s light neutral base oil; (b) 0 to 20 weight percent of a heavy neutral base oil or a brightstock with a viscosity of above about 12 mm2/s to about 40 mm2/s; and (c) at least one performance additive comprising: a polymeric thickener, a dispersant, an antiwear agent, a detergent or mixtures thereof, wherein the polymeric thickener when present has a weight average molecular weight (Mw) of more than 8000 and is present in an amount to provide a total viscosity of the composition of about 12 mm2/s to about 29 mm2/s; the dispersant or detergent when present imparts basicity to said lubricating composition; and the composition has a total base number of at least about 10 mg KOH/g. The invention further provides a method of making the compositions and its use for lubricating an internal combustion engine.
