Is it okay if there is a little water in the engine oil?
1 Answers
Under no circumstances should water be added to engine oil. The relevant information about water entering engine oil is as follows: 1. Water in engine oil: It will cause the oil to deteriorate and change its original properties, preventing it from performing its functions such as lubrication, cooling, sealing, and corrosion prevention, ultimately damaging the engine. 2. Engine water ingress: Once water enters a car engine, at best, the spark plugs may fail to ignite or the engine may stall directly; at worst, it can lead to hydro-lock. 3. Specific situations of engine water ingress: If the engine only has mixed water vapor entering through the air filter, simple treatment is sufficient—cleaning the water vapor from the air filter, throttle valve, and cylinder. If a significant amount of water enters the engine but does not affect normal driving, though the engine noise is louder, it may indicate a small amount of water in the engine oil or gasoline, requiring an oil change and cleaning of related engine components. If a large amount of water enters and the engine has been submerged (not just mixed with water), but the car has not been started and the engine is not damaged, the water must be completely drained, the interior cleaned thoroughly, reassembled, and the engine oil replaced.
