[W126 Coupe] Mineral Oil as a substitute for Brake Fluid

[calvin young]

I solved my own problem and learned a lot about the hydropneumatic suspension fluid.  I recommend all who are interested in the subject go to  http://en.wikipedia.org/wiki/Hydropneumatic_suspension  It talks about the care and use of the system and evolution of the fluids as time and problems affected the system.  

I would like to start a general discussion about using this or another similar type mineral based fluid as a subsitute for the DOT brake fluid.  The reason is that normal brake fluid is hygoscopic, i.e., attracts moisture, and must be changed every year to keep the brakes operating without incident.  This was the reason the manufacturer switched to a mineral based fluid for the hydropneumatic suspension, failure in the systems caused by moisture and dust.  Anyone made the switch or know who has?   Audi uses the Petosin mineral based fluids.  What about the modern MB or Audi cars?
