Overfilling your cars engine oil can cause serious damage to your vehicles engine components and even cause your engine to seize up. Here are some of the consequences of overfilling your oil:

• Foaming: Overfilling your engine oil can cause the oil to be whipped into a foam, which cant properly lubricate the engine. This can cause engine damage and overheating.

• Increased pressure: Too much oil in the engine can cause the pressure on the crankshaft to increase, which can cause oil to enter the exhaust pipe from the crankshaft into the combustion chamber, blocking the combustion chamber hole with oil and eventually clogging the engine.

• Oil leaks: Overfilled oil puts pressure on the engine seals and gaskets, causing them to fail and leading to oil leaks. The excess oil can also cause the oil filter to burst or fail, leading to oil spraying everywhere in the engine compartment, which can cause severe engine damage.

If you notice any symptoms of overfilling, such as smoking tailpipe or high pressure on the oil gauge, pull over and check the oil level using the dipstick. If you have experience working on cars, you can use an oil extractor pump to remove excess oil or drain the oil out manually. Otherwise, get a fresh oil change immediately to correct the problem. To prevent overfilling oil in the future, check your cars owners manual to see how many quarts of oil your car needs and make sure youre adding the correct amount.
