Air conditioner oil

Recommended Posts

hate to say when I don't know for sure, but 5oz. seems low to me .I just went to( sanden usa) and looked at a sd7 which is a common truck compressor and 10oz. is standard comp. fill. However it went on to say that orifice tube systems 240cc. thermal expandsan tube system 135cc.

so I would suggest going to their web site and using their info, they also had the formula to figure extra oil needs based on extra evaporators an longer hose runs and how to calculate this based on refrigerant quantity.
