Re: [DML] Re: AC Question - 3 of them with a little surrounding information.

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.
