I've been changing the oil now every 4,000 Km or so and the oil consumption has decreased at the present. Not sure if the colder winter temps had anything to do with it, but I'm now using 1L / 2,200 km or so.

During my last oil change, the filter was filthy and full of gritty little bits of carbon, but the upper engine does look cleaner than before, so perhaps the frequent changes and good oil (MB 229.51) are helping.

If the car stays at this consumption rate, I'll just add the occasional litre and keep driving. No engine work planned at this point.

Other than this, the car has been running perfectly.
