That sounded familiar, but I wasn't sure, as I thought polyolester and chlorinated refrigerant residue were a bad combination in stationary equipment, but quick research does not indicate any problems. Maybe it was alkylbenzene, but that's a pretty popular choice for low temp R22 systems.
Ebay always has some r12 kicking around somewhere, but not everyone will sell it to you without certification.
