Break Even Point (E85 vs 87 Unleaded)

Anyone have somne reliable information on the above subject. I just do not get out on the road enough in the summer to do ant reliable comparison. In the winter I am out pulling on the road with the fifth wheel.

I been wondering since i thought the fuel gauge had a lead weight on it towards empty when I gassed up with E85.

E85 has 75% of the BTU per gallon of regular ol' 87 octane fuel (with 10% ethanol), so the break-even is when E85 costs 3/4th what regular fuel costs.

So, if 87 octane is $3.20 a gal, then if E85 is less than .75x3.20 or $2.40, then it is a better deal to burn E85. My truck loves E85, you get a little more HP and better charge cooling and higher anti-knock index, so the spark knock sensor will permit earlier timing.
