Synthetic Diesel Oil

Product code : (DOS)

  • Provides improved wear protection, oxidation resistance, aeration control and viscosity control compared to CJ-4 oils
  • Formulated with high levels of zinc and phosphorus additives to protect against wear
  • Resists the effects of extreme heat to help reduce oil consumption
  • Increased dispersancy helps prevent soot from agglomerating into large, wear-causing particles for excellent engine protection
  • Provides better cold-flow properties than conventional oils for faster startup protection and improved cold-weather efficiency

Synthetic Diesel Oil

Formulated to reduce wear and oil consumption in diesel engines used in a wide range of service, including on- and off-road applications. Designed for use with all modern emissions-control systems, helping them operate properly and last as designed.


  • Formulated with durable synthetic base oils and premium additives.
  • Helps minimize viscosity changes while holding soot particles in suspension, helping prevent them from forming larger particles that wear piston rings, cylinders and other critical components.
  • Helps maintain engine compression for maximum power and service life.


  • Premium synthetic base oils naturally resist volatility (burn off) in the presence of elevated heat, reducing oil consumption.
  • Promotes engine cleanliness for maximum efficiency and long life.
  • Reduces the need to top-off the engine between oil changes, decreasing maintenance and costs.


  • Provides excellent all-around protection in both hot and cold temperatures.
  • Withstands heat and resists oxidation better than conventional oils for long oil life.
  • Helps engines remain cleaner and last longer, delivering maximum power and fuel efficiency.
  • Remains fluid in cold weather for fast, reliable startup protection.
