Fortunately, we've got several stations that sell E0 here, and that's all I run, in everything. I add some STA-BIL if they're to sit for more than a month. I've had fuel degrade in a month to the point it caused poor running. Don't know how long it's been sitting in the stations tanks. I've been away half a year and have several vehicles that I filled with E0 fuel, STA-BIL, and charged then disconnected the batteries. After getting back, toping off the batteries, everything fired right up. Even the XL, although it had that stuck needle on the secondary carb. It's much more difficult to track down E0 fuel while traveling, but checking the pure gas website helps a lot.
