I note mixed 2stroke fuel has a bigger quicker problem
as near every time I used a small outboard
I had to pull the carb bowl and drain the water out

any turbo guys run E85 ?
does more alcohol cause more corrosion ?

I am setup to run E-85 (or E-100 for that matter). I am currently running just 93 pump gas. (tuning for E-85 very soon).
You are correct in your statement that its not the ethanol that causes the damage, its the water that separates from the ethanol over time ( Ethanol is hygroscopic).

Most, if not all of us turbo guys that switch over to it use PTFE (teflon) coated fuel lines, bigger injectors, and bigger fuel pumps in order to realize the awesome performance advantage by running it.

And correct, using it in small engines (lawn equip) sucks!

I would only caution people from using petro with ethanol in it, if your car sits for a long period of time, or if its and older car, and has the old school rubber lines in the fuel system, etc.
