unDummy, I don't like ethanol in my gasoline either, and very much dislike how it increases fuel consumption.
Policing ethanol content might be futile, since some are pushing for 15% anyway. But how would stations individually increase ethanol content? Are they adding some E85 to the regular tanks?
I wish the gov would turn it around, and set it at maximum 5% in regular gasoline, and let E85 users drink up the larger share.
