Does adding too much engine oil have any impact?

[DiSkylar]

Adding too much engine oil can easily cause certain adverse effects. Below is a detailed introduction to the consequences of overfilling engine oil: 1. Reduced engine power output: Excessive oil can reduce engine power output. When the engine is running, the crankshaft and connecting rod big end move rapidly. With too much oil, the crankshaft and connecting rod will churn the oil violently. This churning consumes a certain amount of energy, leading to reduced engine power output and increased fuel consumption. 2. Oil burning: Excessive oil can cause blue smoke from the engine exhaust pipe. With too much oil, the rapid movement of the crankshaft and connecting rod big end causes oil splashing, and a large amount of splashed oil can enter the combustion chamber and burn, resulting in blue smoke from the exhaust pipe, known as 'oil burning'.
