Whether .2% water is enough to fizz an Alka-Seltzer tablet I have no idea.

I don't know the answer to any of these questions, but I've run almost
9,000 gallons of mogas through Atlas' Lycoming O-540, without a
burp.

In that time, I would be willing to bet that SOME ethanol-polluted
gasoline has run though his veins. It almost seems inevitable.

Personally, I am skeptical that gasohol is going to harm my 1974-
vintage aircraft. I use the damn stuff in every other gasoline engine
I own, including my 1986 Goldwing, my 1995 Toyota, my 1995 Ford van,
my 1997 Subaru, my 2000 Mustang, my three lawn-mowers, my two yard
blowers, and my one snowblower -- ALL without problems.

But, hey, if the FAA says it's bad, I gotta believe 'em -- so I test
every tank for alcohol.
