A slow leak will carry away very little oil with the freon, however, a catastrophic leak that losses the freon in a matter of a minute or less may carry away enough oil to cause compressor failure. Visible bubbles are normal at start up and until the system temps stabilize. They will return each time the compressor cycles. Minnesota Marshall Red G.
