Well, the dye is mixed in with the oil. Generally speaking, you shouldn't need to add any Pag oil unless a component of the A/C system is replaced (like a compressor or condenser, for example). A professional A/C machine will capture any oil during the recovery process so one can tell if any need needs to be added back in.
