  • Cylinder lubrication of the latest, highly rated low speed crosshead marine diesel engines operating on low sulphur heavy fuels with a maximum sulphur content of 2.5%.
  • 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.
  • Recommendations of the relevant engine builder must be fully complied while selecting cylinder oil as expert views on low sulphur fuels are still evolving
  • Superior thermal and oxidation stability reduces deposit and sludge formation.
  • Excellent detergency minimizes deposits on critical parts viz. pistons, piston rings, ring grooves and cylinder ports.
  • Enhanced anti-wear property minimizes liner and ring wear leading to reduced maintenance costs.
  • Good compatibility with all normal seal materials.
  • Reduced ash level helps in avoiding excessive piston top land deposits which
  • may occur when using 70 TBN oils with low sulphur fuels.
