The reason it weighs 2.04 empty, and 1.6 full is that the butane is lighter then air. Thus, it makes the lighter lighter (no pun intended). The more butane in it, the lighter it is!
Grade 4 Science right there... do your research

Oh, and BTW, Chris, your math is wrong, too. If the empty butane space was a vacuum when empty, sure, adding butane would add mass. However, when you "fill" a butane lighter, you actually replace the air that is originally in the lighter with butane. Thus, if butane were, in fact, lighter than air (it isn't, so Obbear is wrong, too) it would make it lighter. (Helium balloon is lighter than the same sized balloon filled with air.)

Butane is heavier than air, even at STP. Try this: cup your hand. With the other hand release butane from a standard lighter into the "cup." let it sit for a moment and light it. You will soon see butane is heavier than air.

Butane is lighter than air... when both elements are in a gaseous state. While in a liquid state, butane is heavier than air (when air is in a gaseous state) because it's molecules are much more densely packed together. Whether or not its lighter than air doesn't mean it won't have mass, and therefore weight. You can't add mass to an object that already contains mass and get less mass (simple math). If you think this isn't the case, try picking up a full oxygen tank, and then try again when it's empty. I'm just sayin'... By the way, my simple math trumps your 4th grade science.
