My understanding is that there's quite a bit of oil in the coolant
mix. There was oil in the compressor when I got it, and I haven't
added more.

I haven't worried about ruining the 30-YO compressor because friends
have brought in three more (recycled) compressors that I've held in
reserve.

Murphy's Law says that the current compressor won't fail until I've
managed to give away the replacements... :-)
