1998 Montana with rear AC. I can not find in my service manual or under the hood how much oil to place in the new AC compressor I want to install. Does anyone know the amount? I know it's usually only a few ounces but I also know too much is not a good thing. Any help greatly appreciated. I even have the Haynes manual and it says to dump the old oil out into a graduated cyclinder but when I did that, I had ZERO OIL in my compressor. Also, do I add oil to the reciever dryer?
