I usually fill up at BP or Sheetz. Both are E10.. The only place that might not have Ethanol would be Kwik Fill. Their gas is refined in northern PA, www.urc.com
I have not gotten gas there in a long time so I don't know for sure if they switched to E10 yet. Their prices are always higher(not foreign) but I might give it a try if I get better mileage in my car. (If it's cost effective) I average 31mpg in my Saturn Ion with mixed highway/city driving.
My bike runs great on E10 gas so no complaints here.
If it gets worse, I might have to switch to 100LL from Air BP at the airport. I'm sure they wouldn't mind sparing a few gallons after my rental plane gets filled up ;-)
