To provide a method of lubricating a marine diesel 2-stroke engine.
The method includes: (1) a step of monitoring performance characteristics of the engine; (2) a step of selecting a lubricating composition to modify the performance characteristics of the engine, wherein the lubricating composition is prepared by in-situ controlled blending of at least three different fluids comprising (i) a first fluid comprising an additive package with one or more overbased detergents, and optionally other performance additives, (ii) a second fluid comprising an additive package with one or more neutral detergents or overbased detergents, and optionally other performance additives, with the proviso that the first fluid has a ratio of Σ (wt.% of overbased detergents)/Σ (wt.% of all additives in the fluid) greater than that of the second fluid, and (iii) a third fluid comprising an oil of lubricating viscosity; and (3) a step of supplying the lubricating composition of the step (2) to the engine.
