Fuel Stabilizer - serious test!

Yesterday I decided to try to fire up my 2019 Kawasaki Z900RS Cafe motorcycle. It had been sitting in the garage for two years with a 1/2 tank of E10 petrol with StaBil added. I did not intend that it sit for two years back in 2022 but it just worked out that way. Of course the battery was totally dead but I hooked up a Lithium boost thingie and hit the start button. It fired immediately and ran perfectly. Of course the very abused battery (left connected/no charger for the two years) won't take/hold a charge - no surprise there.

I have used StaBil for many years but this was by far the most extreme "test." My typical use on the 328/other cars is for 4-6 months of storage. I'm sure other fuel stabilizers work just as well but StaBil is the only one I have any experience with. Again, this was with maybe 2 gallons of two-year old E10 fuel/appropriate amount of StaBil in the tank!
