That is great if MD's link worked. Not for me.

Don't necessarily trust the labels. Also, they refer to maximum, not actual %. Sometimes it is easier for the station to put labels that say maximum 10% ethanol, and not worry about it. Most purchasers don't care, and some want ethanol.

A blending pump isn't about the nozzle, but rather the underground tanks. Pumps with three grades used to have three tanks to draw from. Each was separate. Modern pumps often use two tanks, one for 87 and one for whatever the highest grade fuel is. All the other grades are blended in the pump. 89 is 50% 87 and 50% 91, for example.

You would need to ask the station operator. Even if they are blending pumps, though, they could be carrying ethanol blends in all of the tanks.
