Subject:Re: A/C question: Ester Oil and R-12 do they mix?

Robert,
Ester oil is compatible with R12 but not compatible with
mineral oil which is general associated with R12. So an R12
system must be flushed of old oils before adding ester oil.

I have not been able to determine if parallel condensors are
beneficial or just a gimmick.
