CAUTION
MIXING OF THE EGME COMPOUND WITH THE FUEL IS EXTREMELY
IMPORTANT. A CONCENTRATION IN EXCESS OF THAT
RECOMMENDED (0.15 % BY VOLUME MAXIMUM) WILL RESULT IN
DETRIMENTAL EFFECTS TO THE FUEL TANKS (DETERIORATION OF
PROTECTIVE PRIMER AND SEALANTS) TO FUEL SYSTEM AND
ENGINE COMPONENTS (DAMAGE TO SEALS). USE ONLY
BLENDING EQUIPMENT RECOMMENDED BY THE MANUFACTURER
TO OBTAIN PROPER PROPORTIONING
DO NOT ALLOW CONCENTRATED EGME COMPOUND TO COME IN
CONTACT WITH THE AIRPLANE FINISH AS DAMAGE CAN RESULT
Prolonged storage of the airplane will result in a water buildup in the fuel
which ”leeches out” the additive. An indication of this is when an excessive
amount of water accumulates in the fuel tank sumps. The concentration can
be checked using a differential refractometer. It is imperative that the
technical manual for the differential refractometer be followed explicitely
when checking the additive concentration.
