Multifunctional Lubricant for low speed marine diesel engines

Shell Melina S is a high performance multifunctional low speed diesel engine lubricant based on a blend of highly refined high viscosity index mineral oils and a balanced selection of additives. It is designed to provide the highest levels of machinery protection in highly rated low speed marine engines, but being multifunctional, can also be used in many different items of marine equipment and used to rationalise the number of grades of lubricant carried on board ship. Please note that Shell Melina S is NOT recommended for trunk-piston engines and in these cases Shell Melina should be used.

Performance, Features & Benefits

  • Improved engine operation and reliability
    Shell Melina S effectively neutralises the highly corrosive combustion acids which can contaminate the main system when cylinder oil drains leak past piston rod glands.

    Good resistance to corrosion results in protection of metal surfaces from corrosion

    Good detergency keeps crankcases and under piston spaces clean and optimise efficiency

    Good air release & antifoam properties mean that air is released from the oil without foaming
  • Lower Maintenance Costs
    Good Oxidation stability combats thermal degradation of the oil and extends its useful life

    Good water shedding properties mean that water can be easily removed by centrifuge

    Extreme pressure properties make the oil suitable many gear oil applications
  • Re-assurance
    Shell Melina S Oil is approved by all major low speed diesel engine manufacturers
