I upgraded the refrigerant in my 1993 Buick Roadmaster from R12 to R134A
when I bought it. The refrigerant was a bit low at the time, so the A/C
wouldn't work.
Got one of those R134A kits at a Wal Mart, discharged what was left of
the old refrigerant and lubricant, and added the R134A. That was 4 years
ago. The A/C has worked like a champ ever since.
I've been told that the problem with changing over is incompatibility
between R134A and the R12 lubricant causing breakdown of the O rings in
the system.
