I have to admit, the whole E15 controversy that has been brewing between the EPA and AMA has me a bit confused. Namely, I do not know how the EPA ever thought that a four-gallon minimum purchase requirement solved anything for powersport users who were concerned about putting E15 in the tanks of their motorcycles and ATVs.
Realizing that a solution to the actual problem had to be devised, the EPA has now dropped the four-gallon minimum on fuel pumps that dispense E10 and E15 from the same pump, and instead the government body says it will likely require gas stations to label shared pumps, as well as offer a dedicated E10 pump/hose for vehicles.
