  • Reduces Friction
  • Minimizes metal-wear by 50% or more
  • Minimizes ‘morning start’/ ‘Dry Start’ wear
  • Increases engine power & pulling power
  • Minimizes engine vibration and noise
  • Lowers heat
  • Extends battery life
  • Protects engine against corrosion
  • Reduces fuel consumption
  • Sustains the quality of engine oil for a longer period of time
  • Provides longer services life for engines and machines
  • Extends oil and filter service life
  • Eases maintenance cost
  • Minimizes electricity consumption up to 20% (a special benefit for industrial machinery)
