"Ethanol is why Americans are getting screwed at the pump” is a heck of a claim when you leave out the value of octane.
Refiners produce lower-octane gasoline blendstock and use
#ethanol’s high octane to bring finished gasoline up to spec.
Octane isn’t free. And lately, it REALLY isn’t free.
At today’s octane values,
#corn ethanol is SAVING drivers ~40–60¢ per gallon at the pump.
