I just finished the reading the mantle thread and remembered I have a couple cans of Coleman fuel that are quite old, one can is unopened the other about 2/3 full. I'm not sure when I bought them and both have the plastic cover but they have to be at least 20 years old. I have 2 double mantle lanterns and a gas stove that have been sitting unused for 18 years and I want to fire them up. I know new fuel is quite pricey and scarce in these parts.
