I have a 1996 Buick Roadmaster Wagon I just got in my New HD6 compressor to reaplace my old burnt up one. I am changing the compressor, orfice tube, dryer, condenser and some O- rings. My compressor came with 0.8oz of PAG 46 in it, but my car calls for PAG150 at 8oz total for the system. Do I just drain out the 46 and put the correct amount of 150 in the compressor?

you drain out the old comp first, and see how much oil came out. then you drain the new one and add the same amount that came out of the old compressor
