I should have said E-85 not 85 octane, it is 85% ethanol but is said to have a higher octane rating then even the 91 octane regular fuel.
I wouldn't use it and have told my wife and kids not to use it in their cars. But there are people that buy it, then complain that your car/truck runs poorly and gets poor fuel economy. Look around I bet you do have it, the pump should say E-85 it is 85% ethanol and can or should only be used in vehicles that have a yellow fuel cap denoting it is a "flex fuel vehicle"

Two different things. E-85 is as you described, 85% ethanol and 15% gasoline. Separately, 85 octane unleaded gasoline is very common in some states. I lived in SD for 23 years. It is (or at least it was) the basic "regular unleaded" grade, just like 87 octane is in Texas.
I remember some stations selling "economy" octane fuel in Michigan but I don't think I have noticed any in years around here.
The reason they sell 85 octane in CO is because when you're a mile up you don't need 87 octane. Your motor just does not needed it when you're a mile high or more. The less air you have the less chance for detonation.
