    Just find out for sure what they are using and what oil that requires. Not all refrigerants want the same oil.

    R12 came with mineral oil. Native R134a was PAG, R134a conversion is typically POE or ester oil which doesn't react badly with any mineral oil that may be in the system. PAG doesn't play nice with mineral oil.

      AC is all back in the car and filled with the proper amount of mineral oil. It will get charged tomorrow by the shop. They use R413. I cross my fingers it will work our well.
