: Do any of you know anything about R406A or Frig-C? They are supposed to be replacements for R-12. I found a fair amount of info about R406A on the web. It is a blend of other refrigerants and is allegedly compatible with the compressor oil and seals, etc. Frig-C is supposed to have the same characteristics, but I didn't find anything. Any actual experiences out there?
I thought 406A was not legal for cars. (I think it is 4% butane?).
I know someone who used it anyway and before it leaked it worked better than R-12
But as previously mentioned, the consituant with the highest vapor pressure leaks first;
blend changes.
Maybe R-134 with upgraded condensor fan?
