Cars prior to 1994 used R-12, and after 1994 all cars were equipped with R-134A. The reasoning for this is because R-12 refrigerant is a CFCs (chloroflourocarbons) which depletes the ozone layer, whereas the more modern R-134A does not contain CFCs.

Why cant you add r12 to r134 what happens?
Why would you want to even consider doing this? R12 is no longer in production and as such it cost almost 4 times as much as R134. But to answer your question, use R12 in a R134 system and you will destroy the compressor as the oil is not compatible with R134 oil.

How do you know if r12 freon is in vehicle?
If if it a 1995 or older then it came with R12 installed. 1996 can be R12 or R134. 1997 up, it has R134/R134a. If you suspect it had R12 look for a label somewhere on the A/C unit signifying it has been converted. If you find it has R12 and is leaking and needs repairing, after the leak is repaired, convert it to R134a. R12 is far too expensive to use.
