What to Do If There's Too Much Engine Oil?

[McLondyn]

If the oil level touches the crankshaft, it's best to extract some of it. The extracted clean oil can be saved for future use, which is the safest method. It is not recommended to remove the drain plug, as it's difficult to control the flow rate, and the drained oil cannot be reused. The hazards of overfilling engine oil include the following: 1. Increased engine operating resistance. If too much oil is added, the crankshaft may come into contact with the oil during operation, creating significant resistance at high engine speeds and affecting engine performance. 2. Increased likelihood of oil burning. If excess oil causes the crankshaft to touch the oil, it can easily lead to oil burning. The high-speed churning of oil by the crankshaft generates numerous oil droplets, which can be easily sucked into the cylinders by the crankcase ventilation system, resulting in oil burning. 3. Carbon buildup and contamination of the catalytic converter. Oil burning can lead to carbon deposits, and some additives in the oil, when burned, can enter the catalytic converter, reducing its conversion efficiency.
