I have a gallon of it out in the shop, but I don't remember what's on the 
can other than dust.

Just remember there are lubricants and then there are lubricants.<:-))

Jet engines use fuel (Keorsean) for a lubricant of some parts. I use it for 
a cutting oil.
OTOH I use WD-40 to lube drill bits when drilling steel, but I prefer 
TapMagic (TM)

WD-40 makes a good lubricant for loosening up frozen engines.  They teach 
that in small engine repair.  Stuck piston?  Take the head off, pour a layer 
of WD-40 on top and come back the next morning. You should be able to turn 
the crank by hand.

It is a lube, but of a very low viscosity and high volalitility.  That means 
it's thin and evaporates much more quickly than 10 or even 5 weight motor 
oil.
