Figure 8-1. Additive Mixing Ratio
CAUTION
Do not allow the concentrated EGME compound to come in
contact with the airplane finish or fuel cell 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 explicitly when checking the additive concentration.
