I have a Mercedes condenser (built in 2014), original fan, orings replaced all over, suction line/crush washers replaced, new expansion valve, new drier (BEHR) and a Spectra Premium A/C Compressor off of r ockauto

System was tested for leaks, vacuumed for over an hour, filled with R134a (2.6lbs) and works perfect on the hottest days. It may take 45 seconds-1 minutes longer to get to ambient cooling temperature but I assure you, it's the same temp coming out of the vents at idle after a minute then R12.

Let's measure and go on the data however - If someone here can measure their vent temps with an true R12 system, I will compare my results and I assure you, they are the same. I have a 1985 300D W123. Stay away from R12 it's terrible for the environment.
