Guys,
Do you know how many ml/cc/oz of compressor oil I have to add to A/C?
I would not like to bother compressor's lines at least they are not leaking and would like to simple replace receiver/dryer and hose (drier-expansion valve) only.
Do you have any ideas about compressor's oil quantity?
I guess that hose belch approx 20..30ml oil only. Maybe little bit more or less. Do we have any chance to measure oil in compressor? Or I have to add just 30..40ml oil in receiver/dryer and that is it?

Does anyone have any experience with such of issues?
