Engine oil sludge is a thick, tar-like gel formed by oil breakdown, soot, and moisture that can block vital oil passages, leading to starvation, overheating, and catastrophic engine seizure. It is primarily caused by short trips, excessive idling, delayed oil changes, and incorrect oil types, but you can avoid it by strictly adhering to service intervals, using premium synthetic diesel oil, and taking regular highway drives to clear out moisture.
