Ethanol has a much lower energy content than gasoline, hence the lower mileage
with gasahol. See here:

('alternate fuels,' not 'alternate facts')
It does, however, have a higher octane rating allowing the huge compression
ratios in dragsters and other racers; which is what produces the massive power
in those engines.

The correct AFR for alcohol (ethanol) is around 8 to 1 versus gasoline at 14.7
to 1. Switching to 10% ethanol should equate to about a 5% richer mixture.
Ethanol produces more power than gasoline ? hence alcohol race engines but much
more fuel required. Your mileage will suffer.
Best regards,
Jim
