Ok after reading another one of your posts we mean two different things by mixing, you mean running a different percentage than 100 and i mean that you can't roll up to the pump with 3/4 of a tank of regular and top it off with e85 (unless that is how you did it every time) the other main issue is that if you mix from a 1/4 tank of gas and then fill it with e85(64% alcohol), if you go back to the pump next time and fill up with e85 you will be running a higher percentage (80% alcohol)

Yes, comm breakdown possibly.
You would never truely fill up in the traditional sense. You would always just put in x amount of E85 and Y amount of gasoline. So say you fill up at a 1/4 tank every time, and always put in 2.5 gallons of E85 and 7.5 Gallons of Gas. Always keeping your ratio 25%, but never running the pump until auto shutoff.
