What Are the Effects of Overfilling Engine Oil?

[MacLola]

Overfilling engine oil can have the following specific effects on a vehicle: 1. Oil may enter the combustion chamber through the gap between the cylinder and piston, leading to carbon buildup. 2. It increases the stirring resistance of the crankshaft and connecting rod, resulting in higher fuel consumption. 3. It may cause oil leakage. Below are some key points about adding engine oil: 1. Adding too little oil can reduce lubrication effectiveness, leading to severe engine wear and potentially causing cylinder scuffing; it may even shorten the engine's lifespan. 2. To maintain the lubrication system, the most important step is to regularly change the engine oil; it is best not to simply add oil. If oil is added frequently over time, it can lead to excessive buildup of sludge and carbon deposits inside the engine, clogging the oil pickup screen and preventing proper lubrication of engine components, which can severely damage engine parts.
