How much oil goes in an AC compressor?

I am replacing an old style York compressor, with a rebuilt one the manuel says i need 7/8 inch on a dip stick, but i remember reading stemware about how many ounces of oil was needed for each component. in the event any part is removed. This methiod seems easier/ more practical than evacuating a system just to check oil level.

How many ounces of oil should I add to the newly rebuilt empty compressor?

My manuals only go back to '67, but it shows the York as holding 10 Fluid Ounces (max).

Is that is for the entire system?? or just The compressor??

so the compressor might only hold 6 ounces of the 10 total??

Did the replacement compressor come with any oil in it? Some do, some don't. If it did, drain it out and measure it. I recommend draining the oil from the drier also and flushing the evaporator and condenser with AC flush solvent to remove any oil from them. Then add 10 oz. total to the compressor.

After running the AC for a while most of the oil in the system is returned to the compressor. At that time, it should still have about 10 oz. in it. You can then check the oil level as you described with the dipstick. You don't need to drain, evacuate and recharge the system to check the oil with the dip stick if you isolate the compressor with the back-seating valves and then take the oil plug out. The procedure is described in the factory service manual.
