Would it be better to use synthetic oil that has a higher boiling temperature? I guess that would only make a difference if the heat is to open pores in the metal, not just thin the oil?

Creative approach. I suspect the benefit of the hot oil bath is to
reduce it's viscosity and facilitate flow into the needle bearings. That
said, there can be little benefit boiling the oil to the point of
smoking as you are damaging the oil at that temp. Seems you may get a
better benefit by bringing the temp up to 250 degrees and no hotter. It
will still flow like water at that temp.

Creative approach. I suspect the benefit of the hot oil bath is to
reduce it's viscosity and facilitate flow into the needle bearings.
That
said, there can be little benefit boiling the oil to the point of
smoking as you are damaging the oil at that temp. Seems you may get a
better benefit by bringing the temp up to 250 degrees and no hotter.
It
will still flow like water at that temp.
