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.

I never used Stabil or other additives.
Have a 5-gal plastic jug for the mower (4-stroke Craftman with Honda
engine) and a 1-gal jug for the mix I use in the whacker (cheap
2-stroke from Sears.)
Transfer from the 5-gal to a 2-gal I use for filling the mower.
If I'm not pouring caps and vents are closed.
That's "proper" storage to me.
My gas usage gets me to the gas station every other year where
I fill both the 5-gal and 2-gal jugs.
So I'm using one or two year old gas often enough.
Never had a problem or noticed anything amiss.
Don't pay attention to running anything dry either.
They always have gas in the tanks when cutting season is done.
They sit idle about 6 months here near Chicago.
Mower always starts first pull, whacker 3 or 4, but you have to know
how to choke it.
Both machines are 8 years old.
Just my experience.
Not my intent to interrupt any Stabil voodoo ceremonies.
