Porsche refrigerant and oil capacity charts

NOTE! Refrigerant and oil capacity guides are based on data provided by sources such as AllData and Mitchell. You should always attempt to verify the information with your vehicle manual or information provided on the underhood stick, sometimes also located on the top of the accumulator. The information provided herein is a reference provided to you at no charge.

The information provided is based, in most cases, on the original OEM specifications. If your vehicle was originally charged with R12 refrigerant, for example, the oil type specified, 'mineral', will not apply.

Additionally, General Motors issues Bulletin # 02-01-39-004B replacing PAG 150 oil with a lower viscocity oil. Thus, TechChoice now indicates PAG 46 (P46D) oil for those vehicles.
