I do. This was the gas that had been sitting in my generator's five gallon tank since 2004. We had been in the midst of a very long power outage, hearing that no relief was in sight, I refilled the tank full, and about two hours later, bang, Gulf Power restores our service. I had been occasionally spiking this gas with some extra Sta-Bil, and running the generator, just to keep the parts "exercised," but even with those 2-3 times a year runs, there was still about four gallons left when I pulled a sample several months ago, and was shocked to see fuel emerge that looked more like apple cider than gasoline. This is when I removed the tank, sequestered the fuel, and ran a small purge of brand new gas through the generator's engine to flush things out. The ugly gas has been sitting in a separate gas can since, and the generator is now dry and free of fuel. Future test/exercise runs will be made by adding a cup or so of gas and running it until it sucks the tank empty.
The eldest can in my "rotating" stock is only two months old, is spiked with FP3K and Sta-Bil, and looks as bright and clear as the day it came out of the pump.
