Lubricating dual-fuel auxiliary engines: a practical approach

For dual-fuel engines running primarily on distillate fuels - including marine gas oil and marine diesel oil - alternating with LNG, more alkalinity is needed in a lubricating oil to handle the sulphur present in these fuels. To achieve the right balance between oil alkalinity and detergency, while helping protect valves from excessive wear and keep the engine clean, Chevron Marine Delo 1000 Marine 40 can provide the solution. The selected additives in the oil promote engine cleanliness and replenishment intervals can be extended with the use of separation and filtration.
