I am driving an 89 100 Quattro and am hoping someone knows the total amount=
 of fluid the power steering unit holds. It leaks, of course, and someone r=
ecomended this stop leak kinda stuff for it and it is in a 10:1 ratio that =
I have to add this stuff. A friend said someone from this list recomended i=
t, so I figured I would join the list and pick some more knowledgeable brai=
ns. Thanks for any input.
