Right now my local Kwik Trip has regular at $2.34, mid-grade at $2.64 and premium at $3.04. Wherever you took that picture is selling all the upper grades at a ridiculous price or it's an old picture. I've never seen such a spread anywhere here.
I also noticed that Kwik Trip E0 is usually 91. Most of the other stations in the non-mandated area of the state just have the standard 93. But since I'm a Kwik Trip fan (but who isn't), I don't mind the 91 if I'm getting E0.
In WI "generally" 91 is E0, but not always. Kwik Trip 91 is almost always E0, though that may be different in Milwaukee county.
Most, if not all, 93 in WI is E10.
We have E0 87 at a station here at 30-35 cents higher than E10 87 across the street.
