All of my (previous) MB Diesels with at or over 200,000 miles were sampled, and determined that at 15,000 mile change intervals they could go another 3-5k miles due to soot level. All other elements were in tolerance as well. Bear in mind that they leaked enough oil that there were several quarts added between changes. The plus side was that my driveway was always nice and black and shed water like a duck's back.
