PRIST Hi-Flash Hi-Flo & Lo-Flo Anti-Icing Aviation Fuel Additive

The fuel additive pilots ask for by name

PRIST Hi-Flash anti-icing aviation fuel additive is a safe, easy-to-handle aviation chemical capable of protecting your aircraft’s fuel system from debilitating and dangerous ice crystals. PRIST Hi-Flash meets the rigorous demands of turbine aircraft use. Best of all, our entire lineup of PRIST fuel additives are less toxic, less volatile, and much easier to use than conventional additives.

Do I Need to Use a Fuel Additive?

All aircraft without fuel heaters must use an anti-icing fuel additive. The formation of ice crystals in fuel tanks can block an aircraft’s fuel line or filter, leading to engine failure. PRIST Hi-Flash fuel additive controls icing in aircraft fuel by depressing the freezing point of water.

PRIST Hi-Flash fuel additive has limited solubility in jet fuel, but it is completely soluble in water. When dissolved water separates from the fuel, some amount of PRIST Hi-Flash fuel additive quickly leaves the fuel and preferentially dissolves in the water, depressing the water’s freezing point. As the fuel gets colder and more water particles appear, an increased quantity of PRIST Hi-Flash fuel additive leaves the fuel and enters the water, ensuring your fuel lines stay clear.

PRIST Hi-Flash fuel additive is recommended for every refueling at a dosage rate of 0.1% minimum to 0.15% maximum by volume.
