Paul, Yes, I do have a new drier,...it will go on just before vacuuming the system down.

BTW, that 10 oz number came off a chart showing specs for the R6 compressor and a typical installation,....


(link to that chart here: http://www.rtitech.com/downloads/News/Oil%20Chart%20-%20Compressor.pdf )


..not a Mercedes 126 spec. Any idea if there is a 126 compressor oil spec anywhere?

Also, my new expansion valve is marked "R134A",....so thinking that it is designed to aid in making the 126 cars more efficient with R134A.
