Alan,
Further thoughts:
Remember the change to gasohol in
cars? The main consideration was about whether materials could stand the
long-term contact with ethanol.
So, in your aircraft, how well do these
things deal with ethanol?
The aluminum of the fuel tanks?
(?good – malt liquor cans have similar concentrations – do they
have a plastic liner or are they just aluminum?)
The sealing compound used in the tank
seams?
Sloshing compound? (Almost certainly
a problem. Is sloshing compound even legal in Coupe tanks?)
Stainless steel fuel lines? Shouldn’t
be a problem.
Flexible fuel lines. Which are
good? Are yours? Are ethanol resistant fuel lines available/legal
for Coupes?
Fuel pump components?
Carburetor parts?
Engine parts?
Then there’s the issue of FAA
approval.
Aviation fuel, 100 LL, is extra expensive
because of transportation problems. If we have to have alcohol free fuel
transported in states where all fuel is gasohol, will we have similar
transportation related high fuel costs?
I sure don’t know the answers.
Those are some of my questions.
(P.S. One source says ethanol’s
freezing point is -114 degrees Celsius. But, in solution with water, it
has different freezing points. What’s its freezing point when in
gasoline?)
