Marine Cylinder Oil specially designed for modern Low Speed 2-stroke Marine Diesel Engines using High
Sulphur Heavy Fuel Oil (HFO).
Product Description:
GP MARGEN MARINE 5070 (GS) is a superior quality Marine Cylinder Lubricant (MCL) designed for
modern low speed crosshead diesel engines operating on residual fuels having sulphur content in excess of
1%. This oil is specially developed for diesel engines operating with higher pressures & temperatures and
longer strokes. This oil is available in SAE 50 viscosity grade with a BN (Base Number) of 70. This oil
possesses outstanding acid neutralizing capability and provides excellent engine cleanliness and durability.


Features & Benefits:
• Outstanding acid neutralizing capability helps to prolong the life of engine components.
• Superior detergency minimizes deposits on critical parts viz. pistons, piston rings, ring grooves and
cylinder ports.
• Enhanced anti-wear property minimizes piston ring & cylinder wear leading to reduced maintenance
• Good compatibility with all normal seal materials.
