Power Steering Fluid Confusion

So after reading for four hours, I have doubts about the specs for early belt driven style power steering pump fluid.
236 is the original service bulletin spec. So I read that a temperature it can be outside the required standard.
345 is the high grade synthetic version called for in newer MB's and if flushed will exceed W164 spec.

So what have those who flushed their system used and what effect did it have on steering feel?
Thanks for replies
