    well i know in vehicles there is about 20% less fuel economy and less power generated per gallon, and in some places it's higher than regular gasoline.
    --ethanol also loves to absorb moisture , so if you keep it in a can, such as 2 cycle, mix in a fuel treatment with it

    I wouldn't use the e85 if they were mine. Most engine manuals say not to use more than 5 - 10 % ethanol. Carbs aren't properly jetted and your engine could run lean.

    Hope this helps

    Even the Kohler EFI engines aren't made to run on more than 10% ethanol. I really think Kohler should do something about that as I wouldn't mind running E85 once in a while.
