clare at snyder dot ontario dot canada quickly quoth:

10% ethanol costs you 5% in power because ethanol has half the
btu/gallon (roughly) of straight gasoline.
If you know one fas is E10, and the other is E0 (straight gasoline)
you are just as far ahead paying $4.20 a gallon of the E) as $4.00 per
gallon for E10.

That 5% power loss results in a 10-11.5% fuel economy decrease in both
trucks I've driven with both fuels. shrug
That will happen with E18.
