I've tried 100% gas vs E10 mix and never could determine a difference in seat of the pants feel or gas mileage. Like others have said, E15 isn't sold in NC at this time (that I've seen) so not an issue.
Don't use your butt, use your brain to tell the gas mileage difference. Divide the miles driven by how many gallons. Simple math for brains, really hard for butts to figure out.

I have had to use E10- in states where that is all that the only choice. I can tell in my 911 the gas mileage difference with shorted distance before a fill up.

You will never notice the performance difference unless you are running really hard and have knock sensors that retard timing. Octane does not add any power but it allows for higher compression. So unless your turbo or supercharged car is tuned for it, it is pointless.
