That's part of the problem when making these global comparisons.

I'm aware that the butane gas we are sold here in the UK is not necessarily the same quality, formula, etc. as that sold in North America. We have problems trying to use the camping gas style butane in temperatures below approx. 5°C / 41°F (in reality somewhat closer to 10°C after factoring in wind chill).
