RE: [DML] Re: Air Condition at Highway Speeds

["Tom Tait" <TTait@xxxxxxxxxx>]

There are R-12 alternative refrigerants - non CFC based which claim to
be compatible with R-12.  In theory you can even use them for a top off.
When these products claim compatibility of that they are certified for
use in an R-12 system, that only means that they are environmentally
acceptable - no guarantee of performance.  I have not tried them. I
guess if someone has gone to the trouble to mass produce and market the
stuff it may be ok,  but I vote real R-12.

eco-friendly??  Never heard of such a thing.  :)

the PO probably switched from R-12 to R-134a..  More for financial
reasons than environmental reasons, but that is a whole different
discussion.

If the system was not flushed, and oil replaced then it is possible you
have damaged the compressor and clogged the system.  R-134a also runs at
higher pressures, and have seen other DML'ers discuss making other
modifications to the system for conversion.  I am not familiar with the
details, because there has never been a good reason to convert.

For anyone considering this now, check out the prices of R-12 vs R-134a.
You will see, it is not worth it to convert...  stick with R-12.
