Local hardware guy who's been in the hardware store business for decades told me this years ago: "Don't use Stabil. Just put fresh gas in the engine with whatever is left and let it run for 10 minutes. It'll work out just fine."
I've done that with gas-powered weed-eaters, snow-blowers and lawn mowers since, never had a problem. Not saying it doesn't work... just saying that maybe it's not needed. 😉
Just my experiences, FWIW.
