Anyway, some of what is posted above is correct, and some is wrong.

Alcohols burn cleaner and cooler and has less energy per pound than gasoline. However, in a modern engine, there is nothing wrong, bad or damaging about running a small percentage of alcohol. Alcohol will slightly INCREASE horsepower, but will reduce fuel economy. Running a tank or two of E85 a year in vehicle so equipped is actually good for the engine and will make it last longer.
Must make it clear, on vehicles so equipped to handle E85 only. Do not run E85 in conventional cars and trucks. The fuel systems are not made to handle that amount of ethanol, and can not deliver enough fuel to properly burn.

As far as being on here, a little water dumped in a tank of E10 gasoline will cause it to separate from the gas, and can lead to running issues if it runs at all. Can be handy in situations when you are trying to disable a vehicle intentionally.
