I have an r-12 ac system. My ac has not been blowing cold so I brought one of those r-134a cans they sell at the auto parts store where u just connect it to the low side line n shoot it in the system. It was a 19oz can that had 16oz of the refrigerant n 3oz of oil. I put the can into my system n realized that my car requires r-12. (Rookie mistake. I know). But if I leave it in my system will this create a problem or will I be okay

impossible..u cant put one in the other as the service ports are different, so if u were to actually put the r134 in ur system its already been retrofitted.

to restate, your car probably has been retrofitted to r134 already if the can was able to attach to the service port with no problems. the r12 service ports are different.

unless he got hold of one of those darn R-12 to 134a adapters, that allow you to do the wrong thing

this .

The majority of old R12 cars have been retro'd at some point to R134a.

If you DID get the adapters and put the r-134a straight into the system without flushing it first, then yes, you will have issues if you leave it that way.

The two are not compatible. as an example, both use different types of lubricating oil. the mineral oil that works with the R-12 will not mix with the R-134A, and you will risk damaging the bejesus out of the compressor.
