Volvo 244 A/C problem

89, 244, R12 system. I replaced the reciever dryer, expansion valve and flushed the system about a month ago. Refilled everything and had great cold air, then it suddenly went to warm air on a very hot day while I was idleing. Ok located problem, leaking seal in compressor. I replaced the compressor with an AC plus, Four seasons New unit, not rebuilt. Unit came with what it said was a complete oil charge. There was no indication if it was the full 6 ounces or just the amount the compressor carries. Anyway I still had the oil in the system I replaced when doing the earlier swap. Now when I disconnect my manifold gauges from testing the compressor I get a hand covered in refrigerant oil. So far I have stopped filling the refrigerant at just two cans, about half the required amount and still have warm air. What are the symptoms of too much oil? And can it hurt the system? And please do not ask me to comvert. Thanks....Max :<)
P.S. Yes the compressor is running while doing all this. Low side gauge is in the low 10-15 range and the high side is low at 125 or so.
