So with fuel canisters they mix propane and isobutane/n-butane. If you use upright stove in winter, the propane will boil off first and your stove will start suffering after 25% fuel used. If you use inverted stove, the propane gas will float ontop of the butane, but because it's inverted it will force liquid butane through the feeder tube maintaining constant high pressure
