Not enough to be worth the trouble.

Moisture from the air will cause the oil to foam and you will get oil in the
air till you run out of oil.

The oil makes them not worth getting involved with scrap.

It would take an oil trap/filter arangement that would let the oil drain
back into the compressor when it was not running.
