And that would be wrong. There is most definitely oil in solution with the refrigerant to lubricate the compressor. Which of course could only be the cause here if the system were leaking refrigerant from the evaporator coil. But since it sounds like this one is cooling ok I'll go with the others on this. It came from within...
