I would not use sta-bil in glow fuel, glow fuel seems to last for years without it, as long as you keep it out of the sunlight and a controlled temperature enviroment. Also if you read on the bottle of sta-bil, it says for seasonal use. If you used it in a gasoline engine or generator, or some engine that may stand around for two years or longer the gas in the tank or carberator may evaperate, and leave a tar like residue in the fuel pump or carberator.
