Up until about last fall, there were still stations that didn't have ethanol at all. Now, some have ethanol in all their fuel, some only have ethanol in 87 octane.
$2.69 for 87 with ethanol, $2.79 for 87 without ethanol.
Next town over has a bigger-name gas station (might be a BP, but I'm not positive - I do know it's the only gas station in that town lol) that has 89 octane with 10% ethanol as their only ethanol-based gas, so you can get 87 octane or 89 octane with ethanol for the same price.
So the true answer to his question is YES, there are still gas stations in Illinois that have non-ethanol fuels. But not anywhere near Chicago, as I've seen.
And now that I'm curious as to the differences between mileage with ethanol and non-ethanol fuels, I may have to fill up with regular 87 octane next time I drive to Chicago and see if I notice any difference in mileage. Sure would be nice to get better than 16mpg in the Blazer. Will post results whenever I do that.
