Just installed a new R134 specific expansion valve, and new (rebuilt) A6 compressor in my 85 380SE. Have prevously flushed the entire system, and will be installing a new drier prior to vacuuming the system down. Have added the required PAG 150 that the A6 calls for with R134A,.....was just checking out Enviro-Safe's refrigerant,.....sounds great,....found one video on Youtube with a guy having just installed it in his 86 Monte Carlo,...and he mentions that his evaporator is icing up at idle.

Wondering if anyone has tried this in a 126 chassis car. They claim its 32% more efficient than even R12!

Anyone tried it?
