Yesterday I finished up re-seal of the AC compressor in my '87 124.193 (shaft seal had failed, sudden discharge of system).


The system has had PAG-46 compressor oil in it, but I made a mistake and re-filled the compressor with mineral oil. I put in 50 CC of mineral oil, and then proceeded to put in two cans of r134 (had planned to use EnviroSafe propane / butane blend but realized too late the I didn't have enough on the shelf).


So, what to do? Flush the system of all oil, and start over, or ???


Does the PAG oil get carried around the system by the refrigerant, and the mineral oil mostly stay in the compressor? If this is true, I'm wondering if I can take it to an AC place and have them evacuate and pull all or most of the PAG oil with that operation, and then I can switch over to mineral oil and not have to flush all the components.
