Correct me if I am wrong. It should be the other way around. The blend refrigerant need to be charged in liquid form. If you charge in gas form the high temp refrigerant is coming out of the tank first (just like what you said when it is leaking). The problem I see when charging refrigerant in liquid form is that the liquid rushing into the compressor, in some case, may damage the compressor.
You will have a hard time trying to find someone servicing your system if your system is anything other than R12 or R134A.
My biggest fear of serving someone else's car is refrigerant contamination. I may end up with unknown blend refrigerant in my R12 recovery tank that will contaminate the next car I servce.
