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

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

Sorry, but ********

Powdered graphite is the best lubricant.

Sorry, but it isn't

PB bearings absorb the oil, they are porous.

Graphite will just clog up the bearing surface

However, if you
must oil it, use sewing machine oil.

For computer fans, yes

for larger bearings really Anderol should be used

Trust me - I have a clue
