Off topic: Here in Lexington, KY ethanol is not required by the authorities, and stations are not required to post whether their gasoline contains ethanol. The only station I've seen post ethanol content is Wal-Mart, so while I don't buy fuel there, I applaud their disclosure.
I am sure that Speedway (for example) has ethanol in their fuel here. How? There is a repeatable difference in fuel consumption between Speedway fuel and Meijer fuel, of about 5%. Wel-Mart fuel produces the same MPG as Speedway (yes, I did fill up there a couple of times, and I've used Speedway fuel many times due to their proliferation here.).
Here Meijer fuel tends to cost a few cents more per gallon than Speedway (2% or less). The only way consumers without lobby power can make a small point is to pay for what they believe is ethanol free. In the end it actually costs less due to the 5% MPG improvement. I see RV and boat owners filling up at Meijer, perhaps they learned the difference early.
Why this off topic post? If ethanol is not required in Alabama there may be stations around with ethanol-free gasoline. If the disclosure is not required it could take some experimenting to find them.
