You would likely get better storage from Diesel with antibiotic stabilizers.

Big problem storing gas with ethanol in it for any time at all. Even stabil doesn't help with the ethanol gas. But if you're storing in a drum the goop should be on the bottom of the drum.
Mercury marine noted some really big problems with phase separation in the their outboards (2 and 4 cycle) and they went around the Dallas, TX area purchasing sample gas from stations and they found that some of the ethanol gas was as high as 30% ethanol. Wasn't an issue for vehicle owners because the gas gets burned quicker, but boat owners sometimes leave fuel in their boats for extended periods.

Stabil has a new formula (green) that DOES stabilise E-10 gas. I have been using gas stored for more than a year, since early LAST hurricane season, in my car and motorcycle. Works fine. My lawn mower sat all winter unused with E10 gas in it's tank, It fired up first pull.
There is also a newer stabilzer called Startron, designed bor boating use. It works well too.
Pri-G has been around awhile, and has many fans. It isn't available locally for me though.
Best bet is to refresh the additive each six months or so. But YES - E10 gas can indeed be stored a year or more.

Been using Pri-G for several years following hurricane Rita. I get about two years storage using Pri-G and have no problems using the gas in any of my engines. YMMV though.
