Could you please elaborate on that? I actually have a totally dry system at the moment, as I have installed new AC lines, a new dryer, and a new condenser. Additionally, I fully drained the remaining fluid in the compressor after spilling most of it. The only area of the system which would be holding any residual lubricant would be the evaporator and piping in the dash.
Is there some recommended value for a totally dry system that I may have missed in the FSM?
