These compressors sometimes have the oil circulating through the whole
system (with the freon). I think if one keeps the compressor upright the oil
will stay in the compressor. It is probably best to have a filter on the
suction side to keep everything clean.

Somewhere (an ancient Scientific American "Amateur Scientist", maybe) I
remember reading about using a refrigerator pump for a rather high vacuum,
but thought you had to do something about feeding it oil. Do you know about
that?
