Can some one help me out?. I'm replacing the AC compressor in my 99A6. I need to find out how much and what type(PAG/POE)oil the compressor needs. I'm thinking its 8oz of PAG oil but i need to know the viscosity. I'm thinking the bentley will hopefully give this information. I was hoping my bently that I ordered online would have came in by now, but still waiting

Thanks
Ray
