We have found that our Kovea remote canister stove with a tight windscreen is seriously more efficient than any of our previous canister stoves and can do far, far more with small amounts of fuel. If there is just a tinsey bit left then that is easily used for car camps that are needed to get all the way to some backpacking. Then when empty we punch a hole in the can and toss it in the recycle bin.

It’s a bit of an equation at times but well worth it. I’ll carry a full plus a partial at times. But as pointed out the steel canisters do weigh an appreciable amount.

I do not trust the can comes with exactly the amount stated. Skeptical that way.
