i just did this on mine and another car, a toyota. it says that you can mix em, but me personally i disconected my compressor, draind the oil. Replaced all my o rings with ones for 134. and replaced the dryer. its 15 dollars worth of insurence. then pulled the system into a deep vacuum(youll need a shop for this,mabe not,dont know who/what you have) then proceed with the kit. its totally worth it to change over. last i checked by me, r12 was 97 bucks a pound
