Finally got my oil analysis back. Lead was high. They said this level could be normal for a freshly built motor but could also mean abnormal bearing wear.
They also said "That usually means there's lead from fuel blow by... and is probably harmless". I didn't think we had lead in fuel these days? Maybe there is still some? I'll need to send in another sample at my next oil change. Anyway here's the report:
