CESSNA SECTION 8
MODEL 182T HANDLING, SERVICE & MAINTENANCE
Diethylene glycol monomethyl ether (DiEGME) compound must
be carefully mixed with the fuel in concentrations between 0.10%
(minimum) and 0.15% (maximum) of total fuel volume. Refer to
Figure 8-1 for a DiEGME-to-fuel mixing chart.
ANTI-ICING ADDITIVE IS DANGEROUS TO
HEALTH WHEN BREATHED AND/OR ABSORBED
INTO THE SKIN.
MIXING OF DiEGME WITH FUEL IS EXTREMELY
IMPORTANT. A CONCENTRATION IN EXCESS OF
THAT RECOMMENDED (0.15% BY VOLUME
MAXIMUM) MAY RESULT IN DETRIMENTAL
EFFECTS TO THE FUEL TANK AND SEALANT,
AND DAMAGE TO O-RINGS AND SEALS USED
IN THE FUEL SYSTEM AND ENGINE
COMPONENTS. A CONCENTRATION OF LESS
THAN THAT RECOMMENDED (0.10% BY TOTAL
VOLUME MINIMUM) WILL RESULT IN
INEFFECTIVE TREATMENT. USE ONLY
BLENDING EQUIPMENT THAT IS
RECOMMENDED BY THE MANUFACTURER TO
OBTAIN PROPER PROPORTIONING.
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.
