I do wish people wouldn't say WD40 is a lubricant. It's not. It's a
solvent - a light paraffin - carrying a small amount of wax - not grease
- and was designed as a water displacer based on a degreaser. This is
documented in NASA's official history of Project Mercury, for which it
was invented. Try lubricating your fan bearings or bicycle chain with
it and see how much it shortens the life, as it washes out the proper
lubricant, as it's supposed to do.
