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

The solutions for excessive engine oil are: 1. Use a large syringe to extract the oil from the dipstick hole; 2. Lift the car, remove the undercover, unscrew the drain plug, and observe the dipstick to drain the oil to the appropriate level. The functions of engine oil include: lubrication, auxiliary cooling, cleaning, sealing to prevent leaks, rust and corrosion prevention, shock absorption, and anti-wear. The method for changing engine oil is: 1. Lift the car, remove the undercover, and place a container of about 10 liters under the drain plug; 2. Unscrew the drain plug, use an air gun to blow into the oil filler port for two minutes, tighten the drain plug after draining, and wipe with a tissue to check for leaks; 3. Reinstall the undercover, lower the car, and use a funnel to add oil into the filler port.
The other day when I was doing car maintenance, I overfilled the engine oil, exceeding the upper limit on the dipstick. Realizing the danger—excess oil can spike engine pressure, potentially damaging bearings and crankshafts, and causing oil foaming that drastically reduces lubrication efficiency—I immediately shut off the engine. I waited for it to cool to avoid burns, then carefully extracted the excess oil using a thin plastic tube paired with a manual pump. I checked the dipstick after every half-liter extraction until the oil level settled between the high and low marks. If you lack the tools, don’t risk driving—contact a 4S shop or repair shop for professional help. Always measure oil precisely with the dipstick when refilling; avoid overfilling to save effort, as it leads to skyrocketing oil consumption and blue smoke. Make it a habit to check oil levels before each refill to prevent major headaches.
