Oil sludge

Oil sludge

Oil sludge or black sludge is a solid or gel in motor oil caused by the oil gelling or solidifying, usually at temperatures lower than 100 degrees Celsius.

Oil sludge can be a major contributor to internal combustion engine problems, and can require the engine to be replaced, if the damage is severe. Sludge is usually caused by the presence of water in the oil, and can accumulate with use. Ways to minimize sludge production and accumulation includes performing frequent oil changes, performing mechanized engine flushing, or de-sludging, or using synthetic oil,[1] and following the manufacturer's engine maintenance routine.
