K100 D+ Diesel Fuel Treatment

K100 D+, formerly known as K100-MD Diesel Fuel Treatment contains enhanced stabilizers to keep fuel fresh, essential for equipment that will sit for extended time between uses. This fluid's unique organic chemistry will even fix equipment that has been sitting a while and won't start or runs roughly. K100-D+ Diesel Fuel Treatment eliminates water in the fuel to prevent microbe growth and winter freeze-ups, improves fuel performance by altering the burn chemistry for more complete combustion, boosting the cetane, and reducing black smoke, pollutants and emissions, and cleans engines and fuel systems while adding lubricity for maximum engine performance and fuel system life.


  • Prevents phase separation in ethanol blended gasoline
  • Eliminates water and all water related problems
  • Stabilizes fuel for up to two years, and keeps it fresh
  • Increases Octane/Cetane ratings 1 1⁄2 to 2 points
  • Replaces lost lubricity in LSD, ULSD and K-1 winter blends
  • Cleans engines and fuel systems for better mileage, easier starts, smoother idle, more power and better acceleration
  • Reduces black smoke, unburned hydrocarbons, CO and particulate emissions
  • Reduces maintenance costs and down time and extends engine life

    K100 D+ is a great diesel additive. It has eliminated moisture problems in the fuel systems on all my equipment including biological growth in the diesel tanks.
