Grant:

Actually there is a weird feature in the GT3/RS where the oil level gauge is reset when the engine cover is opened/closed.  I think because there is really no other reason to open that lid (nothing to see here, move along...), the system checks whether you just added oil.

Well, you live and learn!  Smiley

Doesn't the 991 have a graduated oil level gauge, as its predecessors did?  Smiley
