RECOMMENDED APPLICATIONS
  • High base reserve effectively neutralizes acidic by-products from combustion of high-sulfur fuels to deliver reliable anti-corrosion and anti-rust protection for engines.

  • Excellent base number retention ensures continuous and effective engine protection throughout the oil drain interval.

  • Superior anti-wear property helps prolong engine service life.

  • Outstanding thermal and oxidative stability suppresses high-temperature deposit formation and extends lubricant service life.

  • Premium detergency and dispersancy maintains internal engine cleanliness.

  • Good water separability rapidly removes entrained water from oil and prevents oil emulsification.
