Okay, an empty system with a new compressor holds right at 8 ounces of Pag oil along with 1.6 LBS of R 134 Freon. Normally you add 4 ounces to the compressor and the other 4 into the accumulator . The system will need to be evacuated once its been open up. Once you have evac it for 30 to 40 minutes you can then charge it.
Once you open the system you going to loose any remaining Freon if theirs any even left which is not likely if you had a leaks so there no need to worry about extracting the gas. The only components that you add oil two are the compressor and the accumulator, 4 ounces in the compressor and 4 ounces in the accumulator and then evacuate the system and add your Freon and your good to go.
