We have a 1954 Coleman lantern still. I will never get rid of it. I also have a number of kerosene lamps and several bottles of lamp kerosene. How long does that stuff last if unopened? We have battery-powered stuff for camping, but may break out the coleman this summer. It lives on a shelf in the garage.

I've stored it for longer than that.
