Pentosin and such is for cars with a special hydraulic pump circuit for steering and braking assist. Sometimes this sort of hydraulic sytem will be expanded to control suspension dampers and such. This stuff is a very thin, clear fluid. Must be very special indeed, considering the price!
Many Audis and BMWs have this type of setup.
Standard P/S oil in one of these systems is fatal, and a very expensive mistake to make. [No need to ask me how I know this...]
Anyways, not an issue in this case...
Don't forget to get a new filter.
