[s-cars] A/C compressor oil type?

[Tim Leonard]

I have rebuilt the compressor for one of my S6's. I need to know what PAG
oil to use. The compressor is a Zexel DCW17B. The compressor label states
ZXL100PG oil. Is this PAG 100? Or is it PAG 46 as a chart I found states?
The Bentley has no information as to type/viscosity of oil. I have both
types but I do not know which I should use.
Thanks,
Tim Leonard
