Overfilling the engine oil can lead to serious consequences for your vehicle. When there’s too much oil, it can aerate and foam inside the crankcase, reducing its lubricating properties and potentially causing oil starvation in critical engine parts. This can result in increased friction and heat, accelerating wear on components like bearings and piston rings. Additionally, excessive oil can be forced into areas where it shouldn’t be, such as the combustion chamber, leading to spark plug fouling, increased emissions, and potential damage to the catalytic converter. In extreme cases, overfilling can cause seals to blow out, leading to leaks that can further damage engine components and other parts of the vehicle. Proper oil levels are crucial for maintaining engine efficiency, longevity, and overall performance, making it essential to follow manufacturer recommendations closely and avoid overfilling at all costs.
