I broke down yesterday an bought a pair of respectable ref gauges. I was so sick of under charging/overcharging my ac system. I drained my system, removed my dryer, an blew air through to clear it out. I then re assembled, pumped down, added oil, then freon. (r134). After the third can (I remember reading in a previous thread that is was 3 cans) Im reading 10psi on the low side and 200psi on the high side. Ac is all but disappointing. What are the recommended pressures for this car? Do I need more freon?

Has anybody heard of a refrigerant called MAXI FRIG? I use it in home refrigerators with great success, but I am nervous to install it in my mercedes.

My brother put it in his audi about 2 years ago and says its the best.
