Pag oil is not compatible with r-12. I always use ester oil because it is good for both. Its best to replace accumulater but I'm sure just an ounce or two of pag left in accum. wont hurt. Flush evap. and condensor. And drain as much as you can from compressor. Then add about 4 oz to compressor and 2 onces to condensor and maybe 2 oz in the lines.
