Does my Ford do this as well ? :p Got to be with 1L:300km average !
^^ nope, hate to break the sad news but that's covered in the page Rocke provided :(
Oh dear, what a question! Many reasons for oil burning actually (and I haven't read the page above). Mostly with modern engines it is valve guides after around 70,000 miles but it can be a multitude of things. Big end wear (unusual today), piston ring wear causing pressure blow-by, those are the major causes. I exclude leakages since that isn't actually consumption, just loss and will show up on your garage floor. A simple test; take the car out and warm it carefully. Now go to your nearest decent hill on a quiet day and gun the car to the top. Turn around and half way down take your foot off the accelerator and coast down, accelerating near the bottom. As you do so look carefully in the rear view mirror and see if there is a cloud of oil smoke as you accelerate. If so you have engine wear, in this case it is valves or guides. Simple isn't it?
In my experience the oil consumption of modern engines is not the problem it used to be.
