Same principle? What do price change rules have to do with mandating including ethanol? I don’t get it. Edited to add: Perhaps the ethanol requirement was to decrease the use of actual gas in order to keep prices at the pump from rising as quickly as oil prices were? I don’t know the history. I just know that ethanol is terrible for small engines and terrible for mileage.
