Stabil will keep the ethanol from absorbing water but I haven't seen anything that will keep regular gas from smelling like rotten eggs/sulfur after 90 days. High test will go a couple months longer.

In 1979 I bought a cheap 18" rotary push mower I used for trimming. In the fall shove it in the shed, in the spring add a little fresh gas to the maybe half a tank from last year. Add oil if it was down from last spring, and fire it up. No maintenance, same spark plug, for 18 years it took that abuse, then I gave it to a needy kid. I wouldn't dare do that with today's fuel.
