By me, E85 seems to vary a lot in price. I use the gasbuddy app now. My last fill up was at $1.63, but there were stations selling it at $2.09 as well. I would think ethanol would be cheapest near the midwest just based on the fact that its corn based.

I've only recently started to pay attention to the price of E85, but I think there is a seasonal component to the price as well. What I do is the following.... I take the price of E85 and divide it by my efficiency ratio (call it 80% even though my current one is around 84%). If the resulting price is lower than premium unleaded, then fill up with E85, otherwise use premium. I noticed that my exhaust tips are looking cleaner now too.
