Honestly, I kind of winged it on the oil.
Someone can chime in the total volume, but what Larry says sounds right.
At first, I removed the compressor. From there, you remove the receiver/drier and you have that point separated the system in 2. I disconnect the large nut near the low side port, and pour acetone in it. Chase it out with compressed air.
Be Careful, because acetone eats paint.
Do the same on the condenser side as well. Just deposit the oil throughout the system, as in do not pour it all in one spot.
Then pump down, see if it holds, then start pumping nitrogen to check for leaks. I tested at 200psi. It will vary a little bit depending on ambient temp differences, so as long as it is +/- 3 psi it fine.
