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.

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.
