What to Do If There's Too Much Engine Oil?
2 Answers
If there is too much engine oil, it can be siphoned out. Use a syringe with a transparent tube to pull out the oil dipstick, insert the tube, and siphon the oil. When the oil reaches two-thirds of the tube, seal the top end and pull out the tube, then drain the oil. Repeat this process multiple times to remove the excess oil from the oil chamber. Hazards of excessive oil: Increased operational resistance of internal engine components, leading to unnecessary power loss. Excess oil can also enter the combustion chamber, causing the engine to burn oil, resulting in excessive exhaust emissions, blue smoke, and significantly increased oil consumption. Additionally, it can lead to increased carbon deposits inside the engine, and even premature ignition, knocking, cylinder scoring, severely damaging the engine.
As a car enthusiast, I have encountered the situation of overfilled engine oil and know it is dangerous. Excess oil increases internal engine pressure, causing oil foaming and impairing lubrication, potentially leading to oil leaks or increased consumption. The solution is: immediately stop the engine and let it cool for at least 30 minutes. Check the dipstick; if the oil level exceeds the upper limit, prepare an oil extraction tool like a manual pump or syringe to slowly remove excess oil through the dipstick tube. Extract small amounts at a time (about one liter) and recheck the level until it returns to the midpoint. After completion, start the engine and let it idle for one minute, then turn it off and recheck the dipstick to confirm normal levels. For prevention, supervise oil changes during maintenance, add oil in small increments while frequently checking the dipstick, and develop a habit of checking levels when the engine is cold. Hazards of overfilled oil include damaging seals or the catalytic converter—regular maintenance helps avoid these issues.
