Bio Kleen Diesel Fuel Biocide kills microbes in diesel fuel. The dramatically reduced sulfur content in today’s cleaner burning fuels has created ideal opportunities for microbes to grow in fuel tanks. The first indication of microbial contamination is mucous-like accumulations on fuel-filters and increased requirements for fuel-filter replacement. The only way to get rid of microbial contamination is to kill the microbes with a biocide.

Benefits

  • Benefits

  • Dual-Phase – effective in both diesel fuel and water

  • Effective as a “quick-kill” biocide and for long-term diesel fuel maintenance

  • Kills microbes (bacteria and fungus) that grow in dispersed and free water associated with diesel fuels

  • Prevents fuel-filter plugging – helps prevent fuel system failures

  • Protects fuel system components against organic acids created by microbial growth – prevents fuel tank corrosion

  • Improves fuel performance

  • Reduces engine maintenance costs

  • Effective in all diesel fuels, including Ultra Low Sulfur Diesel (ULSD) and biodiesel blends

  • Safe for use in all diesel engines

  • Will not void engine manufacturer's warranty when used as directed

Year-Round Maintenance Schedule

To ensure peak performance of your diesel, Power Service recommends this Year-Round Maintenance Schedule. Check out our video for more information.
year-round-above-30f year-round-dk
Every time you fill up
If temperatures are above 30°F., add Diesel Kleen +Cetane Boost (silver bottle) to clean injectors, boost power, lubricate pumps and injectors and restore lost power and fuel economy.
year-round-below-30f year-round-dfs
If temperatures are below 30°F., add Diesel Fuel Supplement +Cetane Boost (white bottle) for winter operability. It prevents fuel gelling and protects against fuel-filter icing.
year-round-911
In a winter emergency
Use Diesel 9•1•1 to reliquify gelled fuel and de-ice frozen fuel-filters if your vehicle will not start or gain power in cold weather.
year-round-cd
At least quarterly or as needed
Treat with Clear-Diesel Fuel & Tank Cleaner to remove water, disperse contaminants and ensure fuel is stabilized for long-term storage.
year-round-i-cd-bk
If microbial contamination is present
Treat with Bio Kleen Diesel Fuel Biocide to kill the microbes and Clear-Diesel Fuel & Tank Cleaner to remove the residual water and contaminants.

Did You Know?

Ultra Low Sulfur Diesel (ULSD) fuel has more problems with microbial contamination than previous higher sulfur fuels. Since ULSD can no longer carry water dissolved in solution, more water is shedding to the bottom of fuel tanks, creating a life-support system and breeding ground for microbes. Parrafin content has increased as sulfur and aromatics decrease, providing a major food source to microbes. Additionally, sulfur is a natural poison to bacteria and fungus and its reduction has further exacerbated microbial contamination problems in ULSD.
