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?

Well, the best stuff's called Anderol and it's expensive and minimum of
order of 5 litres

.... so forget that

I've just re-oiled the pb bearings in the fans in a SATA cradle using
the RS equivalent of 3 in 1 oil - it's what I had to hand. For computer
fans you prolly want an oil with not too much drag, try 3 in 1
