  • Recommended for medium speed engines used in marine, power generation and industrial applications operating on distillate fuels having sulphur contents up to 1 %. Specially recommended for older engines where linerlacquer is not a potential problem.
  • Oils of appropriate TBN to be chosen based on the sulphur content of fuel used. Follow manufacturers’ recommendation for selection of suitable TBN level/ viscosity grade.
  • Also recommended for general lubrication of shipboard equipment where specialised lubricants are not required or use of API CF quality oils are adequate.
  • Superior detergency ensures piston and crankcase cleanliness.
  • Improved anti-wear property minimises engine wear and reduces maintenance costs.
  • Excellent thermo-oxidative stability retards oil degradation and controls its viscosity.
  • Reserve TBN ensures protection of engine parts against corrosive combustion products.
  • Better demulsibility characteristics ensure water separation leading to trouble free operation.
  • Special rust & corrosion inhibitors prevent corrosion of engine parts in severe salt water environment.
