Wynn's Ice Proof for Diesel has been developed: 1) to improve diesel fuel fluidity at low temperatures 2) to prevent settling of wax crystals. Can depress the CFPP (Cold Filter Plugging Point) up to -30°C (see table hereafter). (The reduction of the CFPP is dependent on the CFPP & the composition of the diesel fuel which has to be treated.) Prevents settling of wax crystals in the tank. Slows down the formation of wax crystals. Harmless to exhaust gas after-treatment systems. Excellently suitable for diesel fuels used in passenger cars, trucks, buses & boats, as well as for heating & off-road fuels. Also for diesel fuel mixed with max. 30 % bio diesel.
