What Happens If Too Much Engine Oil Is Added?

[VanHarper]

Adding too much engine oil can cause the following hazards to the engine: 1. Reduced power output and aging of the crankshaft oil seal. Excessive oil increases the rotational resistance of the crankshaft, lowering the engine's power output and affecting the crankshaft oil seal. 2. Oil burning and emission failures. If there is too much oil, engine components will churn violently during operation, which not only increases internal power loss but also raises the amount of oil splashed onto the cylinder walls, leading to oil burning failures. 3. Increased carbon buildup and higher fuel consumption. Oil may flow into the engine's combustion chamber, and prolonged oil burning will cause carbon deposits in the engine, increasing the amount of carbon buildup in the combustion chamber. When carbon deposits accumulate in the car, power will decrease, and fuel consumption will rise. 4. Damage to the catalytic converter. As more oil enters the combustion chamber, exhaust emissions will worsen, severely impacting the lifespan of the catalytic converter. 5. Accelerated wear of components. This accelerates the wear of cylinders and pistons, thereby reducing the vehicle's service life.
