Yes, we all know that MoGas is a colloquialism (so is AvGas).
Petersen (the guys with the STC) say:
"The use of gasoline which contains alcohol must be avoided. Gasohol can
damage aircraft fuel systems, decrease range, and significantly increase the
tendency toward vapor lock. Instructions for constructing an alcohol tester
are
included with each STC, or you can order a reusable alcohol test kit from us
by.
Vapor lock is not a common occurrence, but it can develop during hot
temperatures if the airplane has been serviced with winter blend fuel (high
RVP), or
with alcohol based fuel. Fuel volatility also affects carb ice. Carb ice can
occur more quickly on higher volatility fuel."
How are you going to know if there is alcohol in your MoGas if you don't
test? Ask the pimple faced kid behind the bullet proof glass at the HyVee?
I suppose you don't HAVE to test for alcohol in MoGas in just the same way
you don't HAVE to test for water in AvGas.
Why would you ever want ethanol for your plane? The stuff is NASTY.
90/96 AvGas is a viable, permanent solution to the problem. Why don't we all
start pushing for that solution?

Jay, are you going to Oshkosh this year? I will be departing this coming
Thursday. I like to get there early.
BTW, I reread my Petersen STC and there is no requirement or recommendation
that "every tank" of auto fuel be tested for ethanol. It does specifically
prohibit ethanol, as we all know.
One more thing, the word "mogas" is a misnomer. A motor is a mechanical
device which converts electrical energy into mechanical energy. That
terminology may be changing, however, with hybrid cars.
One more thought: With the increase in the use of Ethanol, I would not be
surprised if the auto fuel STCs are not modified to accept a blend of ethanol.
Perhaps with some modification to the engine/airframe.
One more comment, to the best of my memory: Back in the '80s, when I got my
STC, our airport tried to prohibit refueling on the field. Someone call the
FAA and the airport was told, by the FAA, that if they accepted federal
funding, they could not prohibited fueling by individuals. The airport,
however,
was forced to provide a place, at their expense, for individuals to safely
refuel their planes.
So Jay, what day you arriving Oshkosh.
Dennis
