As much as I think ethanol has no place in aviation, outside business class
it really doesn't, the fact is that some of us will have to make the same
decision you have made. Put in your shoes, Thank god I'm not, I'm sure I'd
make the same decision. Just continue to do your drip tests on your tanks.
If you see anything in the gas that doesn't look right find out what it is
before flying. Another thing I wouldn't do is leave gas in the wing tanks
for weeks on end.. If you only fly occasionally then for the twenty minutes
it takes to defuel the plane, it would be worth it to save the possibility
of degrading your tanks and fuel delivery system. Shut off the gas and burn
the gas out of the carb bowls.

Jack,
5% is a very big change. Maybe something is going on that needs
investigation. Adding alky should increase the octane, power, and slightly
reduce the density (mpg).
Most studies indicate higher power and lower MPG with the alky contaminated
unleaded. These studies were for engines designed for non-contaminated
unleaded.
I agree unleaded and syn oil is the choice way to go.

Recently my gas station, like many I hear, stopped selling ethanol-free
gasoline. Bummer. I notice the 5% drop in power. But, Rotax is clear
about the increased maintenance you must perform if you use 100LL. Sunday I
flew to 8000 feet in 95 degree F temperatures, parked the plane on a hot
ramp, then started up and flew home again with no problems. I'm going to
stick with autogas and synthetic oil.

The auto gas in Central Florida now has about 8% Ethnaol in it and has
become a major topic of conversation during hangar flying sessions. An
experienced A&P recommends blending 100LL at a 50% ratio with the 93 Octane
for Rotax 912ULS engines. I'm wondering if this would be a good diet for my
new 912S, which has yet to come out of the box.
