I promise you... Recovery machines remove oil with the recovery. They pull liquid refrigerant out of the system, and oil is dissolved in the liquid. It's why all true recovery machines have oil separators built in.

No one is saying the recovery machines do not take out the oil which is IN suspension in the refrigerant....and remove it from the vehicle ...
Another question is whether the oil holder in a recovery machine can be made empty to start and that recovered and extracted oil is then available for measuring. ? Is it taken out of the refrigerant inside the recovery machine by running the refrigerant though a solvent ? That might preclude an accurate measurement of the oil removed from the system .
