    Gas is no longer in prime condition after 3-6 months, but is still combustible for at least a year or two. Old gas will damage your engine over time though. Most of the degradation is due to oxidization, so if the gas were in sealed cans, maybe it could last longer.

    But yeah, 5+ years in and most gas is unlikely to work in an engine. You’d have to be making some kind of bio-ethanol at that point.
