SECTION 8 CESSNA
HANDLING, SERVICE, AND MAINTENANCE MODEL 208B G1000
FUEL ADDITIVES (Continued)
CAUTION
• Diethylene Glycol Monomethyl Ether (DIEGME) is
slightly toxic if swallowed and may cause eye
redness, swelling and irritation. It is also
combustible. Before using this material, refer to all
safety information on the container.
• Assure the additive is directed into the flowing fuel
stream with the additive flow started after the fuel
flow starts and stopped before fuel flow stops. Do not
allow concentrated additive to contact coated interior
of fuel tank or airplane painted surface.
• Use not less than 20 fluid ounces of additive per 156
gallons of fuel or more than 20 fluid ounces of
additive per 104 gallons of fuel.
PROCEDURE FOR CHECKING FUEL ADDITIVES
Prolonged storage of the airplane will result in a water buildup in the
fuel which “leaches out” the additive. An indication of this is when an
excessive amount of water accumulates in the fuel tank sumps. The
concentration of additive can be checked using an anti-icing additive
concentration test kit. For additional information about this kit, refer to
Chapter 12 of the 208B Series Maintenance Manual. It is imperative
that the instructions for the test kit be followed explicitly when checking
the additive concentration. The additive concentrations by volume for
EGME/DIEGME shall be 0.10% minimum and 0.15% maximum, either
individually or mixed in a common tank. Fuel, when added to the tank,
should have a minimum concentration of 0.10% by volume.

U.S.
CAUTION
If the fuel additive concentration has fallen below
0.035% by volume, the airplane should be defueled and
refueled.
