Why does sludge appear in the oil shell
Sludge is the fuel residue inside the engine. Also known as carbon sludge, it remains in the engine oil and is filtered by the oil filter. However, if the oil or oil filter is not changed, sludge will build up and the oil will become dirty and deteriorate. If the oil is black, it is most likely caused by sludge, so the oil needs to be changed.
