What are the effects of overfilling engine oil in a sedan?

Excessive engine oil can reduce the engine's power output. Here is some relevant information about engine oil: 1. Introduction: Engine oil, also known as engine lubricant, with a density of approximately 0.91×10³ (kg/m³), serves multiple functions such as lubrication and wear reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, and shock absorption. It is often referred to as the 'blood' of a car. Engine oil consists of two main components: base oil and additives. The base oil is the primary constituent of lubricants, determining their fundamental properties, while additives compensate for and enhance the shortcomings of the base oil, providing additional performance characteristics. Additives are an essential part of lubricants. 2. Classification: Engine oils in the market can be broadly categorized into mineral oils and synthetic oils based on their base oil (vegetable oils are not considered due to their scarcity). Synthetic oils are further divided into full synthetic and semi-synthetic oils.
I once accidentally overfilled the engine oil while driving, and the engine noticeably struggled with reduced power and even emitted some blue smoke, which was quite alarming. Later, I learned that excess oil can enter the combustion chamber, leading to increased oil consumption and abnormal emissions. If ignored, this issue can damage seals like oil gaskets and even cause excessive crankcase pressure, resulting in leaks. During routine maintenance, I make it a habit to check the oil level regularly using the dipstick, ensuring it stays between the upper and lower marks. Too much oil is like overeating—it causes bloating, and similarly, the engine bears extra strain. Act promptly by using an oil extraction pump or visiting a professional shop to drain the excess oil, saving you from costly engine repairs. Remember, regular maintenance helps avoid such mistakes.
