Recommended coolant

[iubootgater]

Need to add a bit of coolant to the expansion tank. Actually I'm at the min mark but would like to know what I can top off with. As with most things MINI it's not that simple, lots of mixed info on web. Ideas?
I run Peak long life in everything else but don't want to mix any incorrect fluids.

I would ask Way on Facebook but I believe the coolent is different on MINI's.
