I probably wouldn't add oil, unless you had a leak that was on the lower portion of the piping & noticed dripping , which would still be minimal. There are some recharge cans with some oil in them, if you think you must add a bit. When you say rear system, the oil does not stay back there & is part of the front system & travels trough-out entire system. The oil lubricates the compressor, and too much can cause less cooling & way too much, can lock up compressor. If you change out compressor, or condenser, or evap & clear out lines, then I would seek oil refill capacities. By the way Autozone now has vacuum pump loaner to evacuate system before recharging. Which to me, is really important, I even pass thru some freon after a few hours of vac to help push/flush out any moisture contaminates, & vacuum again. (this was passed on to me from my father-in-law who was a master ac mechanic.)
