E85 yields at least 20% less bang for the buck. In plain language, a vehicle that gets 18 mpg on gas will get 14 or less with E85. Unless E85 sells at a 20% or greater discount to gas, the average consumer has no incentive to buy it

That is from a comment.

And the guy/gal who started this thread asked about E10. E10 (Being 10% Ethanol) That has little effect on mileage. E85 is 85% Ethanol and has a VERY noticeable effect.
