When the engine oil in Porsche gets contaminated with dirt heavily, oil sludge happens. First, it develops on the top of the engine, and gradually it stalls the whole engine. A Porsche operative has to find out the cause of sludge, if he wants to avoid it. Avoiding stop-and-go driving, doing an oil change on a regular basis will prevent sludge buildup. Add motor oil, if you find your Porsche having low oil pressure. Also, follow the maintenance protocols suggested in the owner’s manual and do inspections systematically- in order to prevent oil sludge buildup in your adorable Porsche.
