GP MARGEN MARINE 50100 (GS)

Marine Cylinder Oil specially designed for the latest range of modern Low Speed 2-stroke Marine Diesel
Engines using High Sulphur Heavy Fuel Oil (HFO). It meets the higher performance standards required of
CAT II cylinder oils by MAN ES, particularly for piston cleanliness and deposit control.
Product Description:
GP MARGEN MARINE 50100 (GS) is a superior quality Marine Cylinder Lubricant (MCL) designed for
the very latest 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 brake
mean effective pressures (bmep) longest stroke length and Tier II compliance. This oil is available in SAE
50 viscosity grade with a BN (Base Number) of 100. 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.
• Higher BN for increased acid neutralization capability and OEM’s specified residual BN reserve in scrape
down oil.
• 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
costs.
• Good compatibility with all normal seal materials.
Applications:
• Recommended for cylinder lubrication of MAN Mk 8.2 and Mk 9 engines and Wartsila RT-Flex & WX engines especially for the more severe characteristics of de-rated engines adjusted to operate inside the
power/speed envelope for the engine range and using residual fuels with sulphur contents in excess of
1%.
• The feed rates recommended by the manufacturer should be maintained as the minimum. Higher feed
rates may be required during running-in.
• Periodic inspection of liner condition and scrape down analysis is essential to ensure continuous low
wear rates. Switching from 70BN to 100BN cylinder oil is recommended where there is evidence of cold
corrosion or when using the correct cylinder oil feed rate the residual BN in the scrape down oil is
continuously lower than the manufacturers limit (normally a minimum residual 20BN)
