Features and Benefits

  • Excellent corrosion protection in newer, more demanding engine types during slow steaming operation.
  • Excellent thermal and oxidation stability can lead to reduced deposits and sludge formation. Cleaner engines can lead to reduced component wear rates.
  • Exceptional anti-wear properties lead to potentially reduced liner and ring wear and excellent anti-scuffing control.
  • Outstanding detergency capability leads to potentially cleaner pistons and liners and can help extend periods between overhauls.

Applications

  • Marine crosshead engines
