What Happens If You Add Too Much Engine Oil?

[PeterRose]

Here are the impacts of excessive engine oil on a car: 1. During operation, various components of the engine will experience intense agitation. 2. It increases internal power loss in the engine, causing more oil to splash onto the cylinder walls, leading to oil burning and exhaust issues. 3. Excessive oil creates significant resistance for the high-speed rotating crankshaft and connecting rod mechanism, resulting in reduced power output. 4. More oil enters the combustion chamber, worsening exhaust emissions. In severe cases, it may cause damage or poisoning to the catalytic converter. 5. It increases fuel consumption and oil burning during vehicle operation.
