I have a compressor vacuuming my system and its been on for 10 hours, its at about 28hg. Do you think it will go any lower if I leave it on longer? Also do you think that adding more oil would give a better vacuum (the compressor has lost oil over time whether from shooting it out or from it being in the discharge and the discharge being removed from the system)
