Engine Oil
Engine oil is a liquid lubricant which is used to reduce friction between internal moving engine parts, and dissipate heat from these components to prevent their damage and overheating.
Signs of poor engine oil
- Sludge buildup in the engine
- Knocking noise from the engine
- Low oil pressure
- Engine oil light is on
Engine oil maintenance
- You should always follow the automaker’s recommended oil type and change intervals.
- If your engine oil light is on, this may happen because of low oil pressure, a failed oil pressure sender or its defective wiring. Check the oil level and oil pressure first. Then inspect the pressure sender, oil gauge and wiring if needed.
- Leaking internal oil seals may cause low oil pressure. You should be sure that there are no internal or external leaks before replacing engine parts.
- The engine oil light may turn on due to the low pressure caused by the use of non-recommended oil.
- It is forbidden to drive a vehicle when the engine oil light is on. If so, shut down the engine, wait until it cools down and check the oil level, then top it up if necessary.
