What's a good bearing oil for a phosphor bronze (I think)
bearing in a small computer fan?

"Small bearing oil". Needs to not go gummy with age (3-in1 is
terrible for this) and mustn't contain solvents that annoy the
plastic (some of the Teflon containing oils have additives to keep it
in suspension which are a bit problematic).

I use "Finish Line", because it's what I use on my bike and it's
handy. Break Free or Tri-Flow are useful too. If you don't have some,
get a small bottle because this stuff is always handy.

Sewing machine oil would work fine.

Would a tiny bit of car
engine oil do?

Much too viscous

Yes But....

WD40 will work, if you're really stuck and it's what you have,

Which was designed as a water displacer (WD) with F-all lubricating in it,
even paraffin would be a better choice.
