That's a possibility...

Not since I got the car, probably never.

Fix is easy, evac system, remove receiver/drier and scrap, remove
compressor and drain oil, replace with R134a oil, replace
compressor, install new receiver/drier, evac and recharge with
R134a. Not all that expensive, even if a new/rebuilt compressor is
needed, I'v done it with no problems and found the cooling was not
reduced at all in spite of reading many comments to the contrary.

Unfortunately, I'm no longer able to do that nor do I wish to pay
the cost of having it done. The AC is very likely to remain
non-functional.
