FasFil 5x Filtered Butane... Anyone Heard Of?

But, the words on the label are really no guarantee of what's inside. Only experience or a laboratory test would tell you if its pure enough.

True, but as engineers, when presenting information to the public, we have a responsibility to ensure that people can understand it, ideally with a minimum of confusion and additional explanation. I didn't pick the 3x refining or 5x refining definitions/terms, but at this point they are so widely used it's simpler to just use the accepted term, even if it's not wholly correct, than reexplain everything. This is a cigar forum after all, not an engineering library.
