JP-4 used to be the primary jet fuel for the USAF but was phased out in the s because of safety problems. A few airforces around the world still use it but there is very little production. JP-4 is the military equivalent of Jet B with the addition of corrosion inhibitor and anti-icing additives; it meets the requirements of the U. JP-8 is the military equivalent of Jet A-1 with the addition of corrosion inhibitor and anti-icing additives; it meets the requirements of the U. It is the dominant military jet fuel grade for NATO airforces.

To find out how our extensive refinery fuel additive solutions can meet your refinery needs, please. Preventing the formation of ice in aviation fuels. Despite the stringent measures which have been put in place to eliminate water from aviation fuels, the possibility of free water contamination still exists. In civilian aircraft, fuel heaters can help to minimize the formation of ice in fuels.
However, military aircraft do not generally use these heaters, due to restrictive weight requirements. Fuel System Icing Inhibitor FSII acts to prevent the formation of ice crystals, providing additional security in the event of free water contamination in aviation fuel.
It is a mandatory additive in many military aviation fuel specifications. FSII dissolves sparingly in fuel, but more easily in water. Any water present will extract FSII from the fuel; the additive then acts to reduce the freeze point of the free water, preventing the formation of solid ice crystals which could block the fuel supply system.
