Justice Brothers’ Diesel Fuel Antigel quart bottle will treat up to 250 gallons of fuel in extremely cold temperatures and is approved for biodiesel as well. Additionally, it can be used in passenger vehicles as well as over-the-road diesel trucks. Diesel Fuel Antigel also disperses water in the fuel filter, preventing filter icing and lowering the filter plug point by as much as 35 degrees. It will clean fuel-injector nozzles, lubricate rotary pumps and increases cetane, providing additional power.
