Hi, Paul,

Yeah, an experienced user can go down to 40F if they know what they’re doing, although you won’t have a lot of power. But for the general user, I’ve come around to the 50F number. You have decent power at 50F for a typical two cup boil (long cook times result in more canister cooling; two cups is pretty short and the canister cooling isn’t as dramatic). I should probably update whichever post I put 40F!

I must confess, I saw you listed 40F. Other sites said 50F. So I split the difference/hedged my bets at ~45F +/- . 😀

Thanks, as always, for the great material.

Have a good Thanksgiving!

Re 45F as the cut off for using 100% plain butane, I’m now going more towards 50F after using it for several years, and warmer is better.

With the G Works, one should be able to fill with exactly the blend that came with the canister originally, so the range of temperatures should be the same as when first purchased.

NOTE HOWEVER that plain butane is much safer inasmuch as it has very low vapor pressure. Propane-isobutane mixes (Jetboil, MSR, Snow Peak, etc.) have much higher vapor pressures. Inspect your canisters carefully before refilling.

I’ve been following HJ’s blog for ever and I’m glad to see that he’s posting again.

Hikin’ Jim from “Adventures in Stoving” swears by the butane as he backpacks in warmer weather. His site is an example of gear discussion done correctly. Good stuff!

I have yet to empty one, so I don’t know what they weigh empty. It’s easy enough to approximate the empty weight by subtracting the nominal contents from the full weight, but canisters aren’t always full when you get them. A tiny leak in the valve may allow some of the fuel to leak out. After weighing several canisters, I get a pretty good sense of how much a full one should weigh and I know when to stop when refilling. Being able to refill the canisters makes the smaller ones more economical. No need to carry a big canister or a second small canister on a short trip when you know how much fuel is in your canister. When you get back, refill the small canister from a large one. I like the idea of using the cheap Butane to refill with as long as temperatures are high enough to allow burning Butane.
