What Are the Effects of Excessive Engine Oil on a Car?

[Aniyah]

Here is an introduction to the effects caused by excessive engine oil: 1. During engine operation, the crankshaft and connecting rod big end generate intense agitation, increasing internal power loss. Excessive oil reduces engine output power. When the engine is running, the crankshaft and connecting rod big end move rapidly. If there is too much oil, the crankshaft and connecting rod will agitate the oil violently. This agitation consumes a certain amount of energy, which inadvertently reduces the engine's output power and also increases fuel consumption. 2. It can also increase the amount of oil splashed onto the cylinder walls, leading to oil burning. Excessive oil can cause the engine's exhaust pipe to emit blue smoke. With too much oil, the rapid movement of the crankshaft and connecting rod big end inevitably leads to oil splashing. A large amount of splashed oil can enter the combustion chamber and burn, resulting in blue smoke from the exhaust pipe, commonly known as "oil burning." 3. It affects engine cooling.
