Template:Short description Script error: No such module "Unsubst". Oil sludge or black sludge is a gel-like or semi-solid deposit inside an internal combustion engine, that can create a catastrophic buildup. It is often the result of contaminated engine oil and occurs when moisture and/or high heat is introduced to engine oil.
Causes
Oil sludge may occur due to a variety of different factors. Some of the most common causes are:
- Defective crankcase ventilation system
- Oil/coolant contamination
- Neglecting oil changes
- Low oil level
- Poor engine design
Precautions
Oil sludge is generally preventable through frequent oil changes at manufacturer specified intervals, however, while uncommon, some engines do have a tendency to build up more sludge than others.
