Keep in mind that R12 will keep things colder and the only reason for
changing  the injustry to 134a was environmental concerns. Had nothing
to do with how well it perfomed. From my view point 134a is 2nd best.
new car owners have no choice. 134a is the standard. If you want max
performance in a hot, humid summertime climate - Alabama for example -
stick with the R12. If you are in the high dry country of northern New
Mexico, 134a is great.

Me? I stayed with the R12.
