Rumor has it that Teo Zenios may have mentioned these

Well, I wasn't advocating using WD-40 in the crankcase... :-O
I have yet to see a lubrication guide for indoor-use door hinges...
It's my understanding, and I'm not a lubricant expert, that WD40 is a
solvent, not a lubricant. And that it essentially activates dried or
hardened lubricant. If it's over-applied it washes out the lubricant and
has negative impact, rather than a benefit.
But that's me, contributing to the topic drift.
My understanding does reinforce the idea that WD40 is a solvent, though,
since the thread was originally about using it to clean.
Viscosity
is also a large factor on environment. WD40 works great
on my door hinges in my house, but I use heavy grease on
automotive door
hinges...
Just IMHO,

Real mechanics read the manual that came with the machine they need
to lube, and they also make sure the lube is rated for the
temperature their gear will run in. Last time I checked viscosity is
temperature dependent, so you might need something "thicker" in
hotter climates and something "thinner" in colder ones. If you are not sure, then go ask somebody who
might have a clue (well
works for me anyway).
...and my car dealership uses WD-40 on automotive hinges (which
especially up in the cold, salty north doesn't last very long at all).
They should be the ones with the clue, should they not? ;-P
For quite a few
purposes around the house where something is old and
stuck and just needs to get moving again (not worth the time and
effort for a rebuild) WD40 works just fine.
Which is pretty much what I was getting at...
(Oh, and I'm not a real mechanic, either. I don't even play one on TV!
I'm a geek.)
