I'm surprised that there are a couple examples here of E10-era fuels lasting for so many years. I have not had that sort of luck myself. I had a deceased relative's '96 Fleetwood sit from 2003 to 2011 in an attached garage (semi-climate controlled) with nearly a full tank, after 8 years the gas was completely unusable.
I always use Stabil in my garage queens because they rarely see more than 1-2 tanks of gas per year. But even Stabil only extends the life to 12-24 months at most. After that, it's a gamble with E10 gas.

This thread reminds me. This is the first year I have ever converted anything to flex fuel. I need to top up the tank in the GTO with 93 to cut down on the E percentage since I don't drive it much in winter. I still kept the tank sealed with the factory evap intact when I switched to a sumped and baffled fuel cell, though, so I don't expect much of an issue.

The gas in my Judge had sat in the tank for 18 years - 1983-2001. When I dropped the tank and poured it out, I was surprised to see it perfectly clean and the inside of the tank pristine. Point is to corroborate the finding in this thread: just because gas is old doesn't mean it's bad.

In 2019 I got my 99 out of storage with a full tank of 2+ year old gas in it. Put a fresh charged battery in it, turned the key, and it fired up in barely a crank cycle. I was surprised. Aside from being filthy from sitting in a storage unit and the flat-spotted tires (that somehow were still at 34 PSI), it drove perfectly. I even got on it a little bit after it warmed up and it was ready to go, didn't skip a beat.
5 year old gas may be a different story though.
