I have not noticed a difference between state gases (MN v WI), but definately have with gas brands. I just cannot get the same mileage with holiday gas for some reason.

I have noticed some stations in Wi sell midgrade for the same price as 87 and i think that they are blending higher amounts of ethanol to get to the same price point, but i have not been to those station in a while. Have not seen that in MN, but i typically buy gas close to home (rewards card).

As for the mileage difference... Elevation maybe? Or temperature was higher? I don't know if they have switched over to making summer grade gasoline or not. More likely than not she was driving into a slight headwind also, but its hard to tell.
