I believe, and someone correct me if I'm wrong, that there is an issue with Freeze-12 and slow leaks. Freeze-12 is a blend of R-134a and R-142b. Its the R-142b that carries the oil. If you have a slow leak, the two gasses will leak out at different rates, with the R-142b leaking out faster. You can end up with still enough refrigerant for the compressor to run, but that refrigerant will be mostly R-134a, and no longer capable of carrying the oil used in R-12 systems. So the compressor will destroy itself due to lack of lubrication. On Oct 27, 2005, at 1:27 PM, M. P.
