There is something called turbine oil made for high speed machinery.  I suspect a lot of fine machinery pil is repackaged turbine oil.Sent from my Samsung Galaxy smartphone.

That is no-longer available, but I did some research.  See:-- https://www.cs.uiowa.edu/~jones/pdp8/UI-8/ks7470oil.shtmlI've been using Starrett 1620 Tool and Instrument Oil, because it comes in convenient sized small bottles.One datasheet I found said this is really Nye Delicate Machinery Oil 113, which you can easily buy by the gallon or drum.But, on my small instrument-makers lathe, I use sewing machine oil.  It's clear instead of yellowish, but seems very similar in general characteristics.  You can get it at just about any fabric store.  I learned about this when I encountered a secretary at work deep in discussion with a coworker who restores full-sized steam locomotives for a hobby.  Her hobby was restoring sewing machines, and they were deep in a discussion of freeing old rusted mechanisms, cleaning bearings, degunking and lubrication.  It turns out that an old sewing machine that's been rusting in a barn for 50 years is no more or less a problem than an old locomotive that's been rusting in a city park for 50 years.  Aside, that is, from the matter of size.
