[s-cars] power steering trouble

[Tom Green]

I think this Pentosin brand hydraulic oil is a commercial grade oil,  
German
brand of course, what would you expect?  Perhaps if we bought it in 5  
gal
cans like ford tractors need, the price would come down.  :-)

The real issue is why do these german manufacturers have to produce such
high-performance, close tolerance machinery that requires such specs in
the fluid?  Why can't they be like ford?
