Ester oil is compatible with all pag oils....................
PAG
You will use a PAG 46.
8 ounces of PAG 46 ...replace the drier/accumulator and orifice tube as well.Flush out the condensor also. You can use PAG 100 (i have pag 100 in one of my 97's and itseems to put out better than the other 97 with pag 46, but we will have to wait and see which last longer) but a service bulletin came out a couple years ago from GM, telling the dealships to go to the pag 46....But, all pag oil is compatible with all pag oil. For example: 4 oz. of pag 50 + 4 oz. of pag 150= 8 oz. of pag 100... DONT USE THE PAG 150...IT IS JUST TOO THICK for this compressor....If you have a hard time getting it all inside the compressor,pour the remaining oil into the hose that goes from the drier to the compressor.(suction side...where you add 2-12 oz cans of 134a) Then turn it by hand about 12 revolutions.... And dont forget to evac the air from the system. A/C systems cost toooo much to cut corners trying to save 10 bucks.
8 oz of PAG 46
8 oz. of PAG 46, or PAG 100, or PAG 150 the numbers mean higher the number the thicker the oil. Thicker oil is better in high temp. situations..... p.s. 8 oz. of oil + 2 12 oz. cans of 134a. (if it is completely out)
It depends on the compressor. Consult your local auto parts store for the correct oil. It could be 46, 100,150 PAG or a Hybrid POE oil.
PAG oil goes in the air conditioner compressor. It is added in the same place as the refrigerant. However, this oil must be added before the lines for adding the refrigerant are put in place.

PAG 46
Typically Pag 46, and about 30z. At least that's what it was for my 2000.
For modern vehicles which use R134a, it's PAG.
