Electrical cooling oil has quite different properties from engine oil (and it also used to contain a lot of PCBs!) and would have a good insulating effect, while used engine oil (mixed with dirt etc) probably has some conductivity!

It seems like Oil in the alternator is a GOOD thing! =)
Most of the commercial big ones are oil immersed and cooled. I know this
isn't the same, as oil in the alternator may be fine, but the resulting dirt
that accumulates because of the air cooling fan blowing crap on all the oily
surfaces is not good.

I think it was actually the original one for the car, 170,000 miles doesn't
seem too bad (it is still going now at over 180,000 after the reco!)
I suspect that the wear may also have been accelerated by the oil leak from
the rocker cover that was dripping directly onto the alternator (previous
mechanic didn't put the gasket in properly, and there was a wriggle, and
hence a drip, right above the alternator).

Wow, I have yet to see that one! That armature must have been around since
the 60's and has been in many a rebuild! =)
