What happens if you add too much engine oil?

[JaxsonRose]

The effects of adding too much engine oil are as follows: 1. Various components of the engine will vibrate during operation. 2. Excessive oil will reduce the engine's power output. When the engine is running, the crankshaft and connecting rod big end move rapidly, and too much oil will cause intense agitation of these components. 3. It will increase the amount of oil splashed onto the cylinder walls, leading to oil burning and exhaust issues. 4. It will create resistance to the rotation of the crankshaft. 5. It will reduce the lifespan of oil seals, causing engine oil leaks. 6. It will worsen exhaust emissions and affect the lifespan of the catalytic converter.
