	If you read the label on the WD40 can, you will
notice that at no time do they claim it is a lubricant.
They do make statements which could lead a reader to believe
that it is a lubricant.  They do say that the carrier will
evaporate, leaving WD40 (whatever that is) behind.  They
also say that it is a cleaner (which it is, but have you
ever considered cleaning and lubricating something with
the same substance?).  In my
five years as a motorcycle mechanic I never detected a
residue and I thought it was a volatile fluid.  My
experience and the recommendation of a local bicycle shop is
that it is unsuitable for long-term lubrication (e.g. chains).
It is great for assembling parts which are hard to put
together but don't need lubrication once assembled.
	TriFlow and Dri-Slide have volatile carriers which
leave behind a residue which is a lubricant (Teflon and
molybdenum disulfide, respectively).
This is not to say that I recommend either TriFlow or
Dri-Slide as chain lubricants - I don't have experience
with either with bicycles.
	Motorcyclists have used paraffin as a chain
lubricant with good results.  Dri-Slide is commonly used for
control cables.
