What issues are there with storage?

There is no particular resistance to gum formation compared to any other formulation of gasoline. It is true, the lead doesn't go away, so the octane is retained, but in other respects the fuel can certainly deteriorate. I was wrong in implying it is worse, but it is not any better than other fuels. The lighter components do evaporate in 100LL like other fuel, I just looked that up to verify it. Other than the octane preservation, I think the reputation for storability has more to do with sealed steel barrels than anything else. Apparently, barrels have been found at arctic outposts decades old and were still usable. Of course, Phoenix has a slightly different climate.
