Sort of mixed reviews/thoughts. Very interesting read.
Other sites cover it as well:

Linked from ^ is the following which also has some good info:

So i only looked at the first link, and it contained a little of the same information----mainly about how gas expands at higher temps. Although snopes says its false, when you have temps of 100+, it there has to be some expansion, the tanks can't stay cool the whole time.
