I'm currently changing a compressor and condenser on the vehicle listed above SXL model. I want to be clear on compressor oil replacement. The total oil capacity is between 3-3.7 oz. When I remove the old compressor, I will drain and refill the new compressor with exact amount. However, how much more do I need to add to account for the condenser? Would it be somewhere around 1oz? Also, the old compressor shows a PAG(FD46XG) as an oil type. I'm going to guess this is just PAG 46 I'm normally used to seeing sold. Is this correct?

Yes, that is correct, but I need to say the new compressor usually comes with oil in it already and there is no need to add more. Here is the information needed to complete the job plus I added a video to help as well.

PAG (Polyalkleneglycol Oil) or PAG FD46XG or equivalent

Let it be known if too much oil is added the system will not work well and you will get a vibration when the compressor is on. Please let us know how it goes.
