Just got gas in a Love's in Nebraska. The octane selections were 87, 89 and 91. No indication of ethanol content was on the selection buttons. Off to the side of the pump was a notice that informed that the two lower octanes were both E15 and only the 91 was ethanol free, easy to miss if you are not paying attention.

This was only one station, so I'm not sure if other Love's have the same setup, but something to be aware of. I like Love's Truck stops, but I may avoid them now.
