did you add pag oil before you charged it?

oil lubes the compressor...the oil moves thru the system suspended in the refrigerant. the compressor will has a sump but the oil moves thru the system. whenever the system leaks..its the oil that you see.... oil has the fluorescent dye. whenever parts are replaced oil balancing must be done. whenever the system is evacuated any oil lost must be replaced.

 

I never charged it. I bought a can of a/c pro but when I hooked up the hose it said it did not need freon. Read a little past half way in the green so I did not put any in.
