PRODUCT DATA SHEET
GulfSea Cylcare 5085
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).
Product Description
GulfSea Cylcare 5085 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) longer
stroke lengths ａnd Tier II NOx compliance. This oil is available in SAE 50 viscosity grade with a BN (Base
Number) of 85. 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 MAN Mk 8.2 ａnd Mk 9 engines ａnd Wartsila RT-Flex & W-X
engines operating on residual fuels with sulphur contents in excess of 1% where cold corrosion is not
evident.
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.
If operating at the correct cylinder oil feed rate results in a scrape down analysis residual BN below
manufacturers recommendations, (the typical minimum limit is 20BN) it is recommended to switch
cylinder oil to Gulfsea Cylcare 50100.
