Mike, as long as you don't let the E10 sit in your tank for long periods of time you should be OK. I have friends in the marine industry who have displays with E10 in test tubes which shows the degree of separation over time. It destroys boat outboard motors and the marine industry has lobbied our Congress to not make this rubbish fuel mandatory.
Once the ethanol separates from the gasoline, cannot be recombined. Keep your fuel fresh and you should be OK. With that said, I have friends who tell me they leave E10 in a vehicles for over a year and it still works fine so go figure. I believe the photos are the best proof we need to to keep this crappy ethanol/fuel mixture as fresh as you can.
