Most of the stations in the Cincinnati metro area are now selling gasoline
with 5-6% ethanol. My regular supplier didn't sell gas with ethanol until
recently. Unfortunately I didn't check it often enough and ended up putting
50 gallons of 5% ethanol in my Skylane. When I discovered this, I went
through a great deal of trouble to immediately de-fuel the plane, and refill
with 100LL. Needless to say I was quite annoyed by this.

I have done the water/jar test on most stations in the area and the ONLY
ones not containing ethanol were EXXON and the fuel sold at the Kroger fuel
center.

Looks like you need to test for ethanol each and every time you buy autogas
for your plane.

Conflict with aircraft fuel systems and Ethanol are many:

California formulation is only about 5.7 percent Ethanol, so that
Cherokee 235 may get away with it for awhile, especially if it flies
to other airports and refuels with avgas cutting the percentage even
more.

The bottom line is that at the moment producing Ethanol from corn
wastes more energy than it makes according to experts. The EPA has
ruled California no longer has to use it. But will be some time
before stocks no longer contain it. That's what I read anyway.
