You use more ethanol than normal gas, so you get worse gas mileage with ethanol. But since you use more of it, it works out to about a 1% higher power potential from the same amount of gas, even with its low BTUs. So, it's about the same. Methanol on the other hand has even less heat energy that ethanol, but you need to run so much more of it reach stoich that it ends up making 15-20% more power at the same boost level.
