I read up a little on ethanol fuel yesterday and apparently the refiners make ethanol free fuel - when they get to the distributors they are blended with ethanol to then go to the stations.
They are getting $0.45/gal back for ethanol fuel and there’s Fed quotas that keep going up- so E0(zero Ethanol) is becoming harder to find. If the distributors don’t hit their Fed Ethanol mark they do a ‘cap & trade’ dance - so best for them not to offer E0.
Do you have the link to this?
