It doesn't have to, but in most cases a clean engine on top is also clean everywhere else. Pennzoil's claims are just another marketing angle at something that doesn't need fixing when regular maintenance is done. Since Mobil 1 has taken the top end photos for their marketing campaign, Pennzoil just took something else, that's all.
I have yet to see a clean looking engine on top with stuck rings and burning tons of oil, have you?
