WD40 is absolutely a lubricant (water is a lubricant even), but a poor one

  And when the WD40 you sprayed dries out, and it will, all that is left are sharp little crystals, and these are the source of future squeaking.

    That does not make WD40 a non lubricant, but a poor lubricant. It does lubricate moderately for a small period of time.

    In artillery and similar massive pressure applications are used chlorine based lubricants. These have the ultimate performance as the chlorine firmly attaches to the metal, but it also destroys the surface immediately (which is not a problem in an one shot application). Would you argue that these are not lubricants because of that?
