    摘要: A lubricating oil composition suitable for a trunk piston marine diesel engine. The lubricating oil composition comprises an admixture of: (A) an oil of lubricating viscosity, in a major amount; and (B) an oil-soluble complex overbased metal detergent additive, in a minor amount. The composition is substantially dispersant-free or contains 1, or less than 1, preferably less than 0.5, mass % based on the mass of the compositions, of a dispersant. The composition has a TBN in the range of 3.5 to 100, preferably 8 to 100.

    摘要: A marine diesel cylinder lubricant composition for a marine diesel engine running on fuel having a sulphur content of less than 1.5%, the composition having a total base number, as determined according to ASTM D2896, of more than 30 and less than 70, and comprising at least 40 wt % of an oil of lubricating viscosity, and at least one detergent prepared from at least two surfactants, one of which is a salicylate. The marine diesel cylinder lubricant composition demonstrates good ability to reduce deposit formation, especially on pistons. The marine diesel cylinder lubricant composition also demonstrates good lubrication at temperatures above 250° C.
