What's a good bearing oil for a phosphor bronze (I think)
bearing in a small computer fan? Would a tiny bit of car
engine oil do?

Bronze bearings are usually intended to be self-lubricating.

Until they dry out

You are presuming that they are oil impregnated porous bronze bearings.

I am

Decent self-lubricating bronze bearings

But they're not, they are cheap and nasty, aren't they

have a suspension of lead in the
bronze and don't dry out,
nor do graphite impregnated porous bronze
bearings.

Oiling them
runs the risk of oil + dust creating an abrasive mix that will quickly
wear
the bearing away.

Sorry, but ********

I spent more than a decade making and repairing industrial clocks.

And what sort of RPM are we talking about

completely different animals

One of
the quickest way for anyone to wreck them was to oil the bronze motor
bearings.


Repairing fan motors with PB bearings is part of what I do now for a
living (well, not me personally anymore).

I buy 1000 pb bearings at a time, they are kept immersed in oil for best
results

I do have a clue ...

Sorry, Colin, but you're completely wrong here
