sludge
Sludge is a gooey buildup that can form in the engine oil. If it builds up too much, it can cause the engine to not work properly.
Sludge is a thick, sticky substance that can accumulate in the engine oil due to contaminants and breakdown of oil over time. It can cause engine problems if not addressed.
