What kind of effect should I expect from this change? :/
I have already seen many spouses on our base's FB page very upset with this and say their vans perform subpar at best with E10.
Thank you in advance!

Sounds like you'll have the same fuel as here in Minnesota. Gas with ethanol is all I've known in my 23 years of driving. I always wondered why my vehicles could never achieve the rated gas mileage. I think you'll see a 2-4 mpg hit highway, probably a little worse city. This leads to fuel miser tactics, like removing any unnecessary weight and filling the tires to maximum rated pressure.

You'll be greeting the one armed bandit (the pump) a bit more frequently..

If you haven't done the switch yet, to avoid (or shorten) 'subpar' performance get your tank down to below 1/4 (go till you see the light if you dare) and then fill up to the top.

Sorry, it isn't as bad as everyone says. you'll be fine. There will be a very slight decrease in mileage, but not as bad as reported here.

Enjoy a clean fuel system and cleaner air. No more vapor lock either.

Then why do people in WA state get so much better gas mileage than me? I have a 85 CelicaSupra in very good tune, and the best MPG I could get average was 23. People with the same cars in WA, with much better gas I imagine, can get 27MPG. I managed to get that ONCE on a long drive one way with a tailwind. It's all in the gas formulations and we can't do anything except educate ourselves to find out which brand of gas is best, and the best bang for the buck.

I did mod my 84 Supra one summer to only run on half of the cylinders while light cruising (turned off 3 fuel injectors). It helped get an additional 2mpg, but the original head gasket started letting go from age and uneven cylinder pressures. I replaced the head gasket and removed my "mod".

Even our local dealership called me back to tell me to expect about a 30% decrease in mpg. :/

For an almost new 2013 van? Doubt it - you should see something on the order of 3-4% difference..
Now an '84 supra or even something a decade old will see a bigger drop (6-12% maybe) and can have more problems with old deposits in the fuel system.
