What would be the acceptable oil consumption for a W124 300D?

MB says the "wear limit" is below a quart per 200 miles. I interprete this to mean that the motor is so wore out at this point that it won't start any more.

In practice motors with more than a quart per 1000 miles usage are experiencing some form of failure.

On the older 615/616/617 engines the cars would quit starting during a North Florida winter when they got below a quart every 3-500 miles.

Unlike gas motors the diesel doesn't really mind burning oil. (It will cause carbon problems at times). As long as you have compression and can keep up with the oil, it doesn't matter except as an indicator of age.

Hmmm, Interesting points there. I was just reading the manual and it said a MAXIMUM of 1.5 liters every 1,000 kms. would be acceptable. So I guess if I consume more oil than this that means my engine would be due for an overhaul....?
