I did a little research but most of the threads on this subject are over 3 years old, so I think we could give it another go round. Anybody have any good/bad experiences with converting their R-12 systems with Freeze 12 or R134a. I know R134a is the standard, but I'm being tempted by Freeze 12's potentiel for lower temps and not being known for being as finicky as R134a. I have a very leaky compressor, and R12 is getting harder and harded to find, not to mention $$$. So which would you pick? Also wondering whether to go with a new or reman compressor. I've had bad experiences with remans in the past, some lasting barely past their two year warranty and some lasting onl weeks. However that was almost 7 years ago, so maybe they've improved? Shoot. Added: Doing a little more research and found another blend called Autofrost, if anyone's used that let me know.
