Hello Elkgemeinde, The operating instructions say 4.3 liters, but according to ATU 5.4 liters fit in. And that’s true, because only 5.4 liters reach the maximum level (on the oil measuring rod). Motor B4184S 1.8, 115 Ps, model year 1998. What amount of oil is on your bill? The operating instructions also say that the middle between Max and Min is actually “full”. Which is also quite funny…
