I've had a bottle of Sta-bil for probably ten years, and each season I dutifully put some in the tanks of all the gas tanks I'm putting into seasonal storage. You know, lawn mowers, snowblowers, the old truck, etc. Recently I thought, "How long does Sta-bil (or any gas stabilizer) last?"
I went to the Sta-bil website
http://www.goldeagle.com/sta-bil/faqs_stabil.asp and there in the FAQ's was the answer: "2 years after the bottle has been opened, provided it has been tightly capped and stored in a cool, dry place."
Wow! Now I wonder if I've been doing anything at all to help my engines start up after storage! They all have started without problem, though, so who knows?
I thought this might be of interest to other stovebolters.
