That sample looks very odd to me.. No tin and no lead at all is odd, and what I'd be more concerned with is what's eating up the anti- wear package in the oil. When wear goes up, the package is consumed.

Its possible that the particles of lead and tin that may be present are to large to be detected in a standard UOA. In this circumstance a particulate test is required.

More reasons why a generic UOA isn't valuable. Its all unicorns and rainbows with most.
