What Are the Consequences of Overfilling Engine Oil?

[LondonLee]

Overfilling engine oil can cause blue smoke to emit from the exhaust pipe, lead to carbon buildup in the cylinders, accelerate wear on the cylinder piston rings, and cause carbon deposits on the fuel injectors, affecting the cylinder's operational efficiency. Methods to Address Overfilled Engine Oil: You can drain some oil from the oil pan's drain plug, but ensure the engine has cooled down before doing so. Alternatively, use a syringe and a plastic tube (like those used for IV drips) to extract the excess oil. Normally, the correct oil level should be between the upper and lower marks on the dipstick. Precautions When Adding Engine Oil: When selecting engine oil, strictly adhere to the oil grade specified for your vehicle. If the same grade is unavailable, only use a higher-grade oil; never substitute with a lower-grade oil.
