The old paradigm is that you buy a canister of 4 or 8 oz. It’s kind of expensive. If you go on a short trip, you still have to carry the entire canister even though you only need a little. And when you’re done with a trip, you often have a canister that only has a little fuel in it. There won’t be enough fuel for the next trip, so you have to take a second, full canister, or you’re stuck with some mostly empty canisters you have to figure out what to do with, or you can begin transferring gas between stove canisters to fill up the can for your next trip.
The purpose of this article is to outline the process for transferring gas between canisters so you can maximize fuel use without having to pack along a bunch of partially-filled canisters.
