Also "it could be worse." I recently read an article written by an engineer about the problems and conditions surrounding R410A. He claims that the oil used with R410 retains water VERY aggressively after absorbing it, and that even a deep vacuum "may not" extract water from the oil.

They were talking about a system that had been infiltrated with water, and that it should be flushed out (with a suitable and probably expensive) solvent procedure, then fresh oil added.
