By law when a system has been converted it must be labeled as so, a proper conversion has the shrader valve adapters installed 134a much larger.
if you mix the 2 the oils are not compatible 134a requires PAG or POE oils, R12 uses mineral oil, mixture cause chem brake down of hose, insufficient lube of compressor. component failure, very expensive repair. if you just want to "top up" the system you can use hp40, compatible with both, but very expensive, or the cheaper RedTek, works good for topping up but not good for complete system recharge, RedTek is propane with additives to make it less" explosive " as system pressures and temps rise in system plus the location in an engine bay, gives me the willies.
For peace of mind contact a cert AC tech and have the system checked or converted

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.
Can you put R12 in a R134 system?
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.

Putting freon in 95 ford windstar?
Don't. R12 is so very expensive that you should have your vehicle converted over to use R134. You have a leak or you would be needing to add refrigerant. Have the leak repaired by a professional and have the system converted over to R134. The will remove all R12 & the oil from the system and replace it with R134 & the correct oil. They should pay you for the R12 due to how valuable it is. You may end up spending very little on this repair.

The newer Freon (r134) does not mix with the old Freon. The system needs to be flushed, special oil added so that r134 will be compatible with the system gaskets, then a vacuum pulled. Then the Freon can be added.

What refrigerant does a 1994 Oldsmobile 98 take R12 or R134?
It came from the factory with R12. Unless it has already been converted which you will know by a sticker placed somewhere on the system, I would most definitely have it repaired and then converter over to R134. R12 is just too expensive to consider using.
