Diesel Fuel Supplement +Cetane Boost is a winterizer/antigel that is used in the cold winter months to prevent fuel gelling and keep fuel-filters from plugging with ice and wax. When temperatures drop， paraffin (wax) in ULSD fuel will gel stopping fuel from flowing through the engine， and water in the fuel can freeze on the facings of fuel-filters， blocking fuel flow. It provides trouble-free winter operation for diesel fuel.  Prevents fuel gelling.  Protects against fuel-filter icing. Boosts cetane for faster cold starts. Contains Slickdiesel® Lubricator to protect fuel pumps and injectors from increased wear caused by poor quality Ultra Low Sulfur Diesel (ULSD) fuel.  Effective in all diesel fuels， including ULSD and biodiesel blends. Treats 100 gallons of diesel fuel.
