Gulfmar Cyloil 550

Gulfmar Cyloil 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 & SAE 60 viscosity grades with a TBN (Total Base Number) of 50, 70 & 100. Each grade has got a suffix of 3 or 4 digits in which the first digit indicates the SAE grade (e.g. 5 indicates SAE 50 and 6 indicates SAE 60) and the last two or three digits indicate the TBN. These oils possess outstanding acid neutralising capability and provide excellent engine cleanliness and durability.

Features & Benefits

  • Outstanding acid neutralising capability helps to prolong the life of engine components
  • Superior detergency minimises deposits on critical parts viz. pistons, piston rings, ring grooves and cylinder ports
  • Enhanced antiwear property minimises piston ring & cylinder wear leading to reduced maintenance costs
  • Good compatibility with all normal seal materials

Applications

  • Recommended for cylinder lubrication of the latest, highly rated low speed crosshead marine diesel engines operating on 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 when running new liners and/or rings
