Mixing power steering fluid?

[TopGun2000]

I'm pretty much sure that the old fluid is "Pentosin CHF 11 S" which is superseded by the new "PENTOSIN CHF 202". I need to add some fluid to the steering system. Is it safe to mix them? Thanks.

The Pentosin CHF 202 container states that it is fully compatible with the CHF 11S, but is not compatible with the older CHF 7.........

Thank you. Can I assume that the older CHF 7 was never used in Cayennes?
