82 240d Oil analysis results in

[mabbonizio]

Attached are the results from my 82 240D oil analysis. This motor burns about 1 - 1.5 qts every 3k miles with mostly highway driving (65 - 70 mph) and has 189,000 miles on it. Oil changes every 3k miles with Liquimoly 15w-40 diesel oil and a Mann filter. I have owned it for the past 50,000 miles.

curious about the silicon levels - I just checked and am able to kill the motor by running it and putting my hand over the intake so I presume there are no intake air leaks.

edit - just remembered I recently replaced a torn crank case breather hose.
