Scott -

Most auto gas station pumps in WI & especially MN have only ethanol
laced fuel. But non-ethanol is available in WI at many pumps, and
there are a few pumps in MN at gas stations with a non-alcohol premium
in them. Both MN and WI also have unleaded fuel for airports and
marinas. Just keep asking your FBO for autofuel. He can get it if he
wants to - except maybe in California?
