Customer Benefits

  • Prolongs periods between overhauls
    Proven metallo-organic anti-wear additive system resists wear by forming a protective layer on contact surfaces under all service conditions. Multigrade viscosity provides additional protection against wear at start-up and under high temperature operating conditions.
  • Saves on maintenance
    Metallic detergent and ashless dispersant additive system resists the formation of high temperature deposits in diesel engines. Good oxidation stability resists oil degradation and protects against oil thickening, and oil line and filter plugging.
  • Preserves power and performance
    Metallic detergent and ashless dispersant additive system preserves power and performance by providing good control of high-temperature piston and ring deposits.


The level of alkaline reserve makes it suitable for use with high sulfur fuels at appropriate oil drain intervals.
