Prior to moving to Moab, I lived in MI for three years, and prior to that TN for seven years, and in those states, I used 10% ethanol in most cases and never experienced any problems with any of my vehicles from Pontiacs to Corvettes, and never had any problems with my government vehicles either; at least in regard to fuel.
MI and TN with summer temps in the 90s and humidity extremely high (summer and winter) vs. southern UT where summer temps hit 105, but there is no humidity unless it is raining.
(Just for clarification: TN from 1998 to 2005, MI from 2005-2008, UT from 2008-2014. I guess I could also throw in GA and NY but not sure if there was that much ethanol around then.)
Also add that on some of the GM forums, many advocate on E85 vehicles to run a tank of E85 through the system approx. every 10th fill up to clean the injectors. Not sure if this is accurate, not sure if it works, since my only E85 vehicle is 2013 and I have not lived anywhere E85 pumps are found.
