>>1323361I keep one of these zippo fuel canisters on my key chain, it has a couple refills and it'll last a lot longer if society collapses because the plastic in a bic will eventually age and crack and release its fuel.
It'll be years but it'll still be long before one of these dries up, and i can refill it with whatever kind of fuel i can find that'll burn in a zippo, which is a lot.
