Reply to "A/C oil"

Also keep in mind that if you are mating to the existing hoses, evaporator, condenser etc. they need to be flushed of mineral oil as that and the PAG oil in the new compressor are incompatible. If mixing new and old I always flush both and use Ester oil which is compatible with both. Also change out the expansion valve for an R134a one with a larger orifice.
