Hello,
over here in Germany we have no fuel without ethanol.
Our normal 95 or 98 ROZ fuel has 5% ethanol added. It's called E5.
There is also fuel 95 ROZ with 10% enthanol add. It's called E10.
And some fuel stations offer E85, which means 85% ethanol. But this is for special E85 engines with special fuel lines.
You don't get fuel without ethanol over here in Germany.
There are no problems with E5 or E10 for the 986. Porsche approval for german E10 fuel:

Don't know how german fuel is different from US fuel in detail.
