[V8] Hydraulic Fluid Pentosin 11 v 7.1

[SuffolkD at aol.com]

Sounds right Kneale, as the switch from 7.1 to 11 (letters not off the top of 
my head) was older color to newer color synthetic.  This was done around 
1990-ish.

By the time the V8s were produced, "Pentosin" meant the synthetic 11-S to
Audi.  When they switched to the synthetic, they kept the same part number
for the oil.  Supposedly, you could add the synthetic to older systems, but
you weren't supposed to use the older oil in the newer systems.  Is the
reservoir down to the "minimum" mark?
