compressor oil PAG 46 Or POE (poly ester)

[kermugit]

I have checked to see what oil others are running in the 24v hybrid a/c systems. I get conflicting info on whether to use pag 46 for the denso compressors, but others say this is a no no and use ester oil because it will mix with the residual mineral oil in the old system and r123a. I plan on doing a complete flush on the system. I have a new condenssor e36 lines converted, r134 expansion valve and the complete retro o-rings and desiccant-9 drier.
what oil is everyone running in their system. I want to go the ester route because I have been told that their will always remain a little mineral oil in the system even after a good flush, moreover, pag 46 oil and mineral oil will cause an acid reaction causing a/c breakdown.
Need some clearification.

Thats what I thought.

PAG isn't an option in a system that has had mineral oil in it. You state it yourself in your first post. Ester is the only viable alternative without replacing everything in the system. I don't see a question that needs to be answered, it looks like you'll be running ester. ;)
