I've been on the puregas.org website and I'm not entirely convinced it's accurate. At least for Illinois anyway. For instance, the FS Fast stop stations. FS is a subsidary of Gromark, which is also the parent company of ADM, the largest ethanol producer in the U.S. Think about it. Your best bet is to talk to the manager or owner of your station and confirm it is ethanol free. I delivered gas to stations for about 6 years, in that time the market was up and down, sometimes we blended, sometimes we didn't. That 10% can be anywhere on the pump, it doesn't have to be on the front.
