Consequences of Overfilling Engine Oil in a Car?
2 Answers
Overfilling engine oil in a car can cause various components of the engine to vibrate during operation and result in internal power loss. Here is a detailed introduction to the consequences of overfilling engine oil in a car: 1. Impact on Power Output: It creates resistance to the rotation of the crankshaft, affecting power output and increasing fuel consumption. 2. Oil Leakage: It reduces the lifespan of oil seals, leading to engine oil leaks. 3. Exhaust Emissions: It worsens exhaust emissions and affects the lifespan of the catalytic converter. 4. Power Loss: Various components of the engine vibrate during operation, increasing internal power loss. 5. Oil Burning: It increases the amount of oil splashed onto the cylinder walls, leading to oil burning and exhaust faults.
I accidentally overfilled my car with engine oil before, and as soon as I started driving, I noticed blue smoke coming out, which was really choking. After checking, I found out that too much oil increased the crankcase pressure a bit, causing oil to seep into the combustion chamber and mix with the spark plugs. This not only affected the engine's lubrication but also damaged the catalytic converter. The most annoying part was the sudden spike in fuel consumption, burning through a lot more money on gas. Later, I had to rush to the repair shop to drain some oil, and only then was the problem resolved. This incident taught me to regularly check the oil dipstick and keep the oil level between the maximum and minimum marks. Otherwise, long-term issues like this could reduce engine efficiency and even lead to major failures, which really isn't worth it. Now, every time I change the oil, I pay extra attention to avoid making the same mistake again.
