The biggest issues with ethanol as a fuel are:
- It has a lot less energy thus reduced MPGs. Running full ethanol will result in ~20-25% lower fuel economy than full gasoline.
- Ethanol is hydroscopic, thus takes on moisture if the ethanol sits in your gas tank too long (i.e., 1+ months).
- Ethanol being better for the environment is a total and utter farce. It is misguided, a complete waste of resources, and is very energy intensive to produce. And this is coming from a guy that's been doing environmental consulting since 1998.

I understand the above, was referring to what you posted on its diminished power output in comparison with petrol. Ethanols calorific output as likely you are quite familiar with is quite low in relation to other such fuel alcohols.
I am not in favour with how its produced either, with wasteful corn and such. It being hygroscopic likely more an issue during storage and transport as most consumers tanks dont last to long. But it also means the likehood of you getting shit from the pumps with a high ratio blend is higher than just an unblended gas.
