I thought the same thing but not according to this test. However....

The pressure seems to really drop in the Coleman canisters after a few uses. I've never noticed the MSR pressure dropping noticeably until it was almost empty (of course, taking out cold temperature issues). THAT could be why it seems the Coleman doesn't seem as fast or hot. It could be the pressure drops and you actually have a smaller flame but you don't really notice that the flame is smaller.

Just a hunch.

But I would have bet the farm a Coleman just doesn't give the same performance of an MSR canister, and if the pressure drops as it approaches half empty, then I guess it doesn't.


This is actually what I've noticed to a T.

I thought your first test was done on used containers?

It just seems the PR doesn't roar on the Coleman older canisters, even though they still have fuel in them.


Yeah, we're on the same page here. The first test was done on used Coleman canisters. I wrongly assumed the extended boil times was because of IsoPro burning hotter than the Coleman canister. But with a new canister, the boil times were the same. So the pressure drop of the Coleman is the reason for the extended boil times. I have not noticed that pressure drop in the MSR IsoPro canisters.
