i belive its r12 ... but just get a retrofit kit so u can make it a r134a
You cAnt sorry
Freon R12 refrigerant is so very expensive that I recommend you have the A/C converted to R134a. But first you must have the leak repaired. The shop will then remove any R12 left in the system, flush the system to remove the old oil, install fresh oil that is compatible with R134a, and charge the system. If there is any R12 left they may pay you to recover it.
no
They should never be mixed.
That is only partially true. Legally you must repair the leak before adding refrigerant. You do not have to remove the Freon and recharge it with fresh Freon. However, this is what I would do if it were my car. I am assuming this is a 1996 or older vehicle which contains Freon (R12). I would have them remove all the R12, and give me credit for what they recover. R12 is very expensive, so don't give it away. I would then have the leak repaired and convert the vehicle to R134a. If it is newer than 1996, just repair the leak and recharge the system. You might want to go to a different repair shop, as what they are telling you is only half true. I would not trust this shop.
Freon R12

r12
1993-95 for most.
Contains no (R12) Freon. Freon was banned in 1996.
R134a Freon is an oxymoron, Freon is R12 but the answer is yes, a subtle 'sweetish' odor
