Not a chance. The flow rate is too slow to pick up the (heavy)
oil and drag it along, and once there is a partial vacuum the
transport mechanism pretty much stops. Of course, if you're using
R143a oil it will evaporate under a

According to the MB CD and the instructions that came with the new R-4
compressor from Rusty, oil must be drained from the old compressor and
measured, and new oil added to the new compressor according to a formula.
