Doesn't the ethanol take up the octane rating a bit?  Does that mean they start with extra crappy fuel and add alky?

These wont be ethanol free though. 

Another site I like using.   Gas prices  map. You can put in your zip code or Search by City, State and see the best prices at the gas stations in your area. I have seen 20-30 cents difference at times.  http://www.ohiogasprices.com/Price_By_County.aspx

OK this is just me ok, On my autotune saws I much prefer the 10% ethanol high test gas over non ethanol gas , reason is if you take a saw that runs a carb and set it at as close to perfect for max power that you can then switch to gas with ethanol in it you will find the ethanol fuel burns abit leaner than non ethanol gas , In the autotune saws that run in my air they all run rich so the ethanol gas helps make them run leaner . If you are only after horsepower and given the choice of high test non ethanol pump gas or E85 fuel , No contest the E85 produces alot more power but you have to do lots of carb work to pump enough fuel to the motor , Its about half way between gas and 12026 alcohol/nitro fuel as far as the amount of fuel you need to burn to make power

most people donot think or even know that the more ethanol you can put threw the motor the more power you make , yes a gallon of gas makes more power than a gallon of straight ethanol BUT you can burn up to about 1 1/2 times the volume of ethanol compared to gas so with crab work ethanol makes more power than gas , I have done lots of playing with stuff like E85 and it makes pretty big torque and I find about half way to what we call 120 race methanol for jetting but its about 75% of the power but you can make the motor cut for quite abit longer in cut time over methanol , I would think E85 would make a real good big wood race fuel
