The fun continues w/ my 05 Tiffin Open Rd w/ workhorse chassis. Anyone know how much Pag 46 oil to add. System has been recovered new compressor and dryer installed.New compressor is Delphi and they state 2 oz for it alone. I need to add for the rest of the system i.e. Condenser dryer hoses and evap. Tiffin was not sure. Has the Denso system. I find all kinds of numbers on the net. Most seem to say 8 oz for the entire system. Any experience down this road?
