After replacing the condenser, evaporator (and heater core), and expansion valve on my 82, I need to add some compressor oil. As I understand, the original oil was mineral based. I have a bottle of "Estercool Oil-R12 & R134 Refrigerant Oil-Compatible with mineral, PAG, Ester, Paraffin". I plan to recharge the system with a portion of my remaining 11 lbs of R12. Has anyone experience with this product or additive oils in general? The label gives me a green light but, having flushed AC systems before, I plan to proceed with caution.
