A small amount of additive to make sure the ethanol's water retention does not affect uncoated metal parts is a simple solution.
In Automobile engines, 10% ethanol will reduce your MPG by about 1%. This is NOT a big deal.
Yes - higher concentrations or static-times in tanks will affect resins. It may soften natural rubber, but will not really affect synthetic rubber much. Uncoated aluminum is a problem in higher concentrations.
Ethanol can take the place of all the REAL problem chemicals in fuel today - benzine, touline, etc as the octane ENHANCER of choice. E85 is 105 octane acting as even higher octane in certain instances because of its chemical cooling properties.
Its a GREAT fuel when used properly with basic, easy to understand when researched best practices. I think of all forums, this one should be above this mob-lynching of a chemical with no research or understanding.

I'll be the first in line to be a cheerleader for ethanol once they stop using CORN as the source.
Until then, it's just another BS political talking point.

And is a much more effective anti-knock than lead ever was.
'85-'86 32V (S3) with stock chips can normally use 89 octane ('Plus' or middle-octane) without issue.
Here the low-grade 87 octane is usually "pure gas" and the premium 91 is "pure", but most all the mid-grade 89 octane is ethanol blend so I have always steered clear of it. Is it okay to use the ethanol blend 89 octane, or am I doing the right thing by steering clear of it??
Ha missed this! Do you know who has rebuild kits in stock just in case? Regular suppliers seem at a loss...

Here in Oregon, all the gas has 10%. And there is no separate mid-grade, it's mixed in the pump from 87 and 92. AFAIK, as long as the octane rating is correct, you should be fine.
Having some ethanol in the fuel will lean out the A/F ratio a little. (A percentage of the E?? percentage.)
Has anyone had luck with this site. It shows 5 stations in my area, two of which are owned by an ethanol producer, 2 that have up to 10% ethanol stickers on their pumps, and one I did not know sold gas (I need to check them out).
It's a crowd-source platform. It's only as accurate and up-to-date as the information that users add to it. Since the EPA changes the required gas formula with the seasons, a station might sell ethanol during part of the year and not in other parts of the year. Unless users of this website constantly update the data with the seasons, the info is apt to be of little use.
At one time, Phoenix area gas stations were required by the EPA to sell oxygenated fuel (of which ethanol is a type) during half the year (summer, IIRC). The rest of the year, most stations sold ethanol-free gas. I don't know what the rules are today.
