To ensure proper mixing, the following is recommended :
– For best results, the alcohol should be added during the fueling operation
by pouring the alcohol directly on the fuel stream issuing from the fueling
nozzle.
– An alternate method that may be used is to premix the complete alcohol
dosage with some fuel in a separate clean container (approximately 2
to 3 U.S. Gal – 7 to 11 litres) and then transferring this mixture to the tank
prior to the fueling operation.
Any high quality isopropyl alcohol may be used, such as anti–icing fluid or
isopropyl alcohol (Federal Specification TT–I–735a). Figure
provides
alcohol – fuel mixing ratio information.
Ethylene glycol monomethyl ether (EGME) compounds, in compliance with
MIL–I–27686, if used, must be carefully mixed with the fuel in concentration
not to exceed 0.15 % by volume. Figure
provides EGME – fuel mixing
ratio information.
