I actually did an experiment a few years ago:

I filled a 5-gal can with regular gasoline in July 2015 and added 2 oz of Sta-bil (from AutoZone) as per the instructions - cool little measuring method in the Sta-bil bottle, btw. In late November 2016 I used it and my car engine ran perfectly fine - pretty interesting considering that that gas had been stored in my garage for 16-1/2 months and gone through half a summer, a full winter and then a full summer again.

I'm not fond of the idea of keeping a flammable substance like that in the garage, but 1) I had no other place and 2) consoled myself that it was in a new military, metal jerry-can with good seals.
