I recommended a four-pack of oil samples, not a 1-shot. However, even one sample can be valuable, as the lab will provide the "normal" values for comparison.
Attached is a sample of M1 5w-40 after 5000 miles of use in my '87 wagon with OM603. All wear levels are normal, soot was below 1%, indicating that I probably could have gone another 5k miles without exceeding the soot limit.
