ICE-5 fuel system icing inhibitor (FSII): a fuel anti-icing additive for turbine fuel that acts as a fuel icing inhibitor. ICE-5 is mixed in the fuel at rates of 0,10% up to 0,15% by volume. If the aircraft has no heating system for the fuel, small amounts of free water in the fuel can freeze and block fuel lines, filters and valves. Properly used ICE-5 will prevent icing of the water in the fuel system. A positive side effect of ICE-5 is inhibition of bacteria-growth in fuel tanks.

ICE-5 complies with ASTM D4171-03, chemical properties according to MIL-DTL-85470 (replacing MIL-DTL-27686), DEF STAN 68-252, AL-41. NATO Code number S-1745.
It is very important to mix carefully the fuel with the icing inhibitors such as ICE-5 DiEGME! Just pouring the product in the tanks will result in insufficient mixing and separation of the inhibitor and the fuel. For direct addition at refuelling, ICE-5 aerosols are very handy. The aerosols are delivered with a flexible tube and a clip for direct dosing in the stream of the jet fuel which is coming out of the nozzle. ICE-5 is usually mixed in the fuel at rates of 0,10% - 0,15% by volume.
Shelf life: 36 months
