Customer Benefits
  • Maintains power output – The detergent/dispersant additive system provides control of high temperature deposits in areas such as the undercrown of the piston and the piston ring belt area, enabling piston rings to function efficiently.
  • Prolongs oil life – Base Number (BN) level and superior alkalinity retention characteristics maintain adequate BN to ensure corrosive acids formed by the combustion of fuel sulfur are effectively neutralized, thereby minimizing liner wear.
  • Efficient purifying system performance – Excellent water separation characteristics enable water to be centrifuged out with essentially no loss of additive.
