MoGas users: Ethanol replacing MTBE

Another reason for high prices now, is that some states have
mandated a ratio of E85 to regular petroleum gasoline in
pump sales. But there is a shortage of alcohol so when they
run out of E85 they can't sell straight gasoline. Maybe the
President's lifting the EPA rules will also alter state law,
he is blamed for the shortage, hope he has the power to wave
a magic wand and fix the market shortage of refineries,
distillation plants and political unrest in the world. But
it isn't that easy.
First thing, build more refineries, second nuke IRAN so that
the uncertainty about the future supply will go away. It
will also remind a lot of people that it is better to fight
a nuclear war when only one side has the bomb. We will use
small, 3 to 300 kilo ton deep earth penetrating bombs to
take out the underground hardened factories with minimal
above ground damage or radiation release. As the Fonz said,
"You've got to hit someone every once in a while" to keep
your reputation.

Not sure what nuking Iran has to do with motor fuel gas STCs for
aircraft.

Don't believe everything you here about "minimal" radiation release or
collateral damages either. And don't forget to duck when the favor is
returned. There are plenty of heavily contaminated nuclear horror shows
(NTS, Hanford, Rocky Flats, INEL, Oak Ridge, Savannah, etc) in the US
and they weren't even being used in attacks. Underground atomic bomb
testing (not to mention earlier open air tests) in Nevada have resulted
in large scale underground contamination, and those were drilled down a
lot deeper than any penetrating bomb could hope to optain. As far as
hitting someone once in a while, I believe the USA has done that quite
recently. It's worked great, hasn't it? Meanwhile I'm curious about
how increased use of ethanol in motor fuels is affecting aircraft that
use motor gas under an STC.
