As far as I know all 87, 89 or 91 have 10% Ethanol, unless sold differently as a separate non methanol grade and at big $$$ premium (like Sunoco does at some places).
Come to Minnie-soda, all 91 that I am aware of is ethanol free. One of the few benefits in this State. Pretty sure SD and Wi. 91 is E-0 as well.

Diesel fuel is also adjusted for the balmy weather in Mn.
