What happens if too much engine oil is added?

[BrodyDella]

Here is the relevant introduction about excessive engine oil: 1. Oil burning fault: Excessive engine oil causes intense agitation of engine components during operation, which not only increases internal power loss but also leads to more oil splashing onto the cylinder walls, resulting in oil burning faults. 2. Power reduction: It creates significant resistance to the high-speed rotating crankshaft connecting rod mechanism, leading to decreased power output. 3. Catalytic converter poisoning: Increased oil entering the combustion chamber worsens exhaust emissions. In severe cases, it may cause catalytic converter poisoning and damage. 4. Increased fuel consumption: It raises vehicle driving fuel consumption and causes oil burning.
