How Many Times Should the Engine Oil Be Changed After Water Intrusion?
2 Answers
Engine oil should be changed twice after water intrusion. Here are the specific details about the engine: 1. Definition: An engine (Engine) is a machine capable of converting other forms of energy into mechanical energy. 2. Internal components: It includes internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. For example, internal combustion engines typically convert chemical energy into mechanical energy. Engines can refer to both power-generating devices and the entire machine including the power unit (such as gasoline engines, aircraft engines).
That day my car's engine got flooded after driving through water, and I was extremely worried, so I immediately asked a friend for help. Water entering the engine can cause the oil to emulsify, leading to lubrication failure, and in severe cases, it can cause cylinder scoring or even total engine failure. The number of oil changes needed depends on how severe the water ingress is: if only a small amount of water got in, one oil change might suffice; but if a lot of water entered, especially if you attempted to start the engine, you’ll need two or more oil changes to thoroughly flush out the contaminants. In my case, I changed the oil twice—after the first change, the oil was still milky, so I had to change it again before it became clear. Never attempt to start the engine to avoid internal damage; towing it to a professional repair shop is the safest option. When driving, avoid forcing your way through deep water—always check the depth before crossing to save yourself major trouble.
