Yes, all automobiles manufactured after 92-93 utilize R-134. R-12 is still available on the market but requires a special certification to purchase. R-134 is less effective than R-12 but car manufactures make up for this by building more efficint A/C systems.

If you mix r12 with r134 air conditioning system, it will cause a high pressure in your airconditioning system and eventually damage the compressor and the evaporator. R12 is only for r12 aircon and something with r134, it can't be mix.
NO ! and Why?
IF no more freon will go into the system, that means the pressure is higher in the system than what is in the can. If it is still not cooling, you may need to have the system evacuated and recharged to ensure you have the exact amount of refrigerant the system requires to cool at its best.
Go to Walmart or an auto parts store. Buy an a/c recharge kit for R134 freon coolent. Follow the directions on the can..
it could be either or if its R-12 it needs to be converted

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.
