Re: How much oil to add to AC compressor?

I would suggest a complete refill, because after a compressor body leak, you can't be sure how much oil is still in the system. You should install a new orifice tube, too, that way when you remove the old one any oil in the evaporator will drain out too. When you put it back together use "PAG150" oil in the pour bottle. Spread it out by pouring it in different parts of the system. Add the majority to the compressor and turn it by hand to allow the oil to coat everything. You don't want the compressor to dry start under load.
