Daft question maybe but i have never seen a dipstick as awkward to read as tge one in my Z. M54 3.0. Actually has a dipstick.. that's a start. ... question is where is the max level.
Is it at the top of the cut away section or is it at the top of the plastic centre section?
Should the oil cover the last metal rod part.
