[Vwdiesel] Power Steering Fluid

The Mobil, Chevron and Shell products I mentioned were found to be relatively similar in performance at the heat ranges specified for the Pentosin hydraulic fluid Audi recommends, and lots of Audifans.com email listers reported successful use.  The only 1980s Audis that used regular ATF were some of the smaller-bodied sedans and coupes that had vacuum-assisted brake systems instead of the hydraulically-boosted brakes.

  For some reason I was thinking the A1/A2 PS systems could use 
ATF like so many cars in the past?  I know the Audi 5k's of the mid 
80's would leak all over if anything but the recommended fluid 
was put into them.  The only substitute I'd heard of prior to this 
was baby oil.  Smells funny but one shop used it in "dying" systems 
for people because it was much cheaper and "couldn't hurt!"
  So the Mobil, Chevron, etc are a substitute for that oil or is that a 
whole new, proprietary oil they're for?  (it wouldn't surprise me)
  Then:  How do those compare to the oil my '96 Passat calls for?
Why can't they just use hydrualic oil or universal tractor fluid or 
something!  :-P
