I need to add some hydraulic fluid to the pump for the Vario roof. I have seen in a few threads here that some suggest adding the CHF11s Pentosin that is being used in the ABC system. Other threads have mentioned that it should be the Febi fluid. The fluid in my pump is more of a clear fluid not green like the CHF11s. Can these fluids be mixed to top off the pump and is there any danger in going so?

I put CHF11S in mine, no issues.
