CESSNA SECTION 8
MODEL 182T HANDLING, SERVICE & MAINTENANCE
The introduction of alcohol or DiEGME compound into the fuel
provides two distinct effects: (1) it absorbs the dissolved water from
the gasoline and (2) alcohol has a freezing temperature depressant
effect.
NOTE
When using fuel additives, it must be remembered that the
final goal is to obtain a correct fuel-to-additive ratio in the
tank
, and not just with fuel coming out of the refueling
nozzle. For example, adding 15 gallons of correctly
proportioned fuel to a tank which contains 20 gallons of
untreated fuel will result in a lower-than-acceptable
concentration level to the 35 gallons of fuel which now
reside in the tank.
Alcohol, if used, is to be blended with the fuel in a concentration
of 1% by volume. Concentrations greater than 1% are not
recommended since they can be detrimental to fuel tank materials.
The manner in which the alcohol is added to the fuel is
significant because alcohol is most effective when it is completely
dissolved in the fuel. To ensure proper mixing, the following is
recommended:
1. 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.
2. An alternate method that may be used is to premix the
complete alcohol dosage with some fuel in a separate
clean container (approximately 2-3 gallon capacity) and
then transferring this mixture to the tank prior to the fuel
operation.
