Ethanol from my searching has 28% less energy, summer vs winter E0 varies in energy content, but averages within 3% of E10. don't know if summer or winter blend of E10.

Search E10 vs E0 & E85 to find some older threads with links I've found and my experiment results.

Basically Stratus(non FFV) MPG = energy content almost perfectly.
Impala & suburban(both FFV) suffer about 16-18% loss in mpg on E85 vs E10 instead of energy content 25% would predict.

Also search the internet for North Dakota Ethanol Blend test, sure looks like a scientfic test where some of the test cars (only 4) get better MPG with higher E content so lower energy content, contrary to what I'd expect. There is also a Finland test comparing E5 & E10 with interesting results. Check out the emission results on the North Dakota test as well.

I don't have a dog in the hunt, just tired of people saying ethanol sucks without any data to back it up. I'm just trying to collect/record data on blends and FFV cars.

I'm really just looking to find the cheapest way to get to work.
