Stabilizers added to fresh fuel will maintain gasoline freshness for
9-12 months

Of course, untreated gasoline will stay "fresh" for 270-360 days if
properly stored.


You have a reference for that? And what defines "properly stored"?
Everything I've seen says you get a few months in typical storage
conditions most of us would use. Gas now has ethanol in it which
makes it even more problematic. I'd use stabil to go from one
season to the next, but would never let untreated go a year.

"Good quality gasoline should be stable almost indefinitely if stored
properly. Such storage should be in an airtight container, to prevent
oxidation or water vapors mixing, and at a stable cool temperature, to
reduce the chance of the container leaking. When gasoline is not stored
correctly, gums and solids may accumulate resulting in "stale fuel". "
