Fuel for winter storage?

[KHvistagt]

There is a gas station in my area that sells gas without ethanol but its 89 octane. Currently, I am running a brenspeed 93 tune and use 93 but it has 10% ethanol. Would it be better to change the tune and store the car with the non-ethanol fuel for the winter or should I just add stabil to the fuel thats in it?

leave your 93 in there and add some Stabil. also start the car in the winter and just move it back and forth in the driveway, if the streets are crap. Also buy a battery tender. I do this every winter.

I put her away with sunoco 100 unleaded,ethanol based fuels have a short shelf life even when treated properly,not worth the risk imo.

My Stang and motorcycle fire right up when I use Stabil. Wouldn't store it without Stabil it either way.
