Mine has been burning oil at about the same rate as yours. It started at about 100,000km and I'm just over 200,000. I've mentioned it to the dealer here numerous times and they monitered it but never took action to do anything about it. Now the dealer is closed and I started to go to another dealer and I got told some oil consumption is normal but they wouldn't disclose at what rate. I've tried different oils giving each 2 or 3 oil changes but nothing changes. Always keep an extra litre available in the truck for when the light turns on.
