all petroleum based oil is a petroleum distillate
the lighter the oil the closer it is to a volatile solvent
after all they separate crude by heating it to distill the oils based
on their volatility
so take the component info you glean from the warning label with a grain of salt
I can see that about 3n1 oil (WD-40 is a more extreme case of what you
describe),
so I withdraw its recommendation
and, coincidentally, sewing machine oil IS #10 machine oil :^)
you can get a spray can of slicone oil (not grease)
it will have a long straw to inject the oil into the bearing which
could wash out any binding hair/dirt
it does not turn sticky either, but it is super light so reapplication
may be needed if a lube is all the fan needed
as a side note,
silicone oil is also a great conditioner for the rubber seals around
your car doors, trunks, windows, etc
