Oil can carry it into critical engine parts.
Bearings, cams, lifters, rings, and gear trains will all experience premature wear unless soot is removed from the oil. But ordinary filtration won't work on micron-sized particles. The best way to protect your engine from the effects of soot is through ultra-fine filtration. Ordinary filter media cannot remove particles that do the most damage. Picture a filter as a screen.
