R134a conversion

This weekend I picked up an R134a compressor and drier since my old compressor is broken and runs on R12. I'm planning on emptying the system and installing the new parts and converting it to R134a before it gets above 70* here.
Now since I'll be converting, I'll have to use the PAG oil for my lines and evaporator, but I still have whatever R134a oil is sitting in my new compressor and drier.
Question is can I mix the two oils or will I have to by a good amount of PAG and flush out the entire system?

Re: R134a conversion

My understanding unless you can change out/flush out everything you should use mineral oil, wont cause any reactions with the R12 stuff.
