What happens if your oil is sludge?

Oil sludge will first appear on top of the engine, inside the oil pan, and on the valve cover. The sludge can then block the siphon, and consequently hinder the circulation of oil within the engine. Sludge usually build-up due to several reasons, but driving in heavy traffic repeatedly is one of the main causes.
