AC mineral oil and PAG oil mix

My indy says that it is now OK to use PAG oil in old R12 systems and that they(mineral & PAG oil) will mix and work well together. Anyone have an update on this subject? Past threads that I've found really don't deal with this subject directly except to say that O rings might be weakened by the PAG oil. I will be staying with R12.
