Adding fuel stabilizer after the fact will not fix the fuel.

As for running it - depends on the engine. I would say you can get

with fairly bad fuel in an I/O and not have much problem - especially if
you mix say 50:50 w/ fresh 92/93 octane.

Why use higher octane?

I don't know if the higher octane has anything to do with helping out with
the stale gas situation. I do know that with my old I/O, the compression
and/or timing was set up in such a way that low octane fuel caused knocking,
dieseling, and my mechanic told me, would cause damage.
