Overfilling your car’s engine with engine oil can indeed harm your engine. Engine oil plays a crucial role in lubricating engine components and regulating temperature. When you overfill the engine with oil, it can lead to several issues. First, excess oil can create excessive pressure inside the engine, potentially damaging seals and gaskets. Additionally, the crankshaft may come into contact with the oil, causing foaming and reduced lubrication efficiency.

Furthermore, overfilled engine oil can lead to increased friction and heat, potentially causing overheating and reduced engine performance. It’s essential to maintain the correct oil level specified in your car’s owner’s manual to ensure proper lubrication and prevent engine damage. If you suspect overfilling, consult a mechanic to assess and rectify the situation promptly. Regularly checking and changing car engine oils at the recommended intervals is crucial for the engine’s longevity and performance.
