Not much info on mbworld. Some guy recharged his S Class W126 with success below.

Anyone try it in the C63?

 

Isn't that stuff illegal? This is bringing me back lol but, I vaguely remember some stuff from A/C class in technical school. I'm pretty sure that stuff is illegal in most states as of the early 90's... 12A has its benefits over R134A, but is it really worth it? Sure it performs better, puts less stress on the compressor and stuff along those lines... But to go through the ENTIRE process for cooler air? I'm sorry if I'm lending any valuable info but, what exactly is the point?

 

I forgot to mention why I'm asking lol. I need to get mine serviced.

Thought I'd give the conversion a try after using the pro seal.
