Determine the amount from the manual. Most are 6 1/2 or 8 oz. I think. If the system has been completely and thoroughly flushed everywhere, pour a few ounces in the evap, a few in the condensor, a dab in the compressor and a few ounces in the receiver.
If it has NOT been flushed, it's a guessing game. There are little disposable gadgets you can get to push onto a port and get an oil sample. You can get an idea with them if it is over or under charged with oil, but it's still a guessing game.
Hope this helps.
