It's better than nothing, but if you're going all in, then go with the system that will give you all in performance.
Hi Al, I saw one of posts from Aug. 3rd on oil capacity. If I understand your post correctly, this is what I should be looking at for proper oil in the newly rebuilt system.

New March P414 Compressor (Sanden 7176) - already comes pre-filled with 100 cc of pag oil. I cannot find the exact type of pag oil yet.

So, if I flush all the lines, then I should add an additional amount of pag oil (exact type TBC) for each additional component based your post from Aug. 3rd..

Parallel flow Condenser - 1 oz
Evaporator - 3 oz
Dryer - 1 oz
New r134a POA valve - 0 oz ??
New Expansion valve - 0 oz ??

I plan to just pour this oil into each component, button up the system, then move the clutch on the compressor clockwise twenty turns or so before I vacuum and charge. Do I have this right ? Do I need more oil for the new POA valve or expansion valve ? Thanks !
