There's quite a bit of metal in this sample. The averages show how this engine tends to wear after
4,800-mile intervals. If the interval on your sample is right (who knows for sure since you just bought it),
then some of this metal might be accumulation. Otherwise iron can show steel wear, with copper, lead, and
tin suggesting quite a bit of bearing wear. Some lead might be from leaded fuel, but with copper and tin also
showing up, there's a good chance at least some of this is from bearings. Monitor for low oil
pressure/engine noises. Check for air intake leaks (silicon).
Thank you in advance.
