What to Do If Engine Oil Is Overfilled?

[LaCayden]

Excess engine oil can be siphoned out using a transparent plastic tube. The problems caused by overfilling engine oil are as follows: 1. Insufficient power: When the oil submerges the engine's crankshaft, an excessively high oil level increases the resistance to the crankshaft's rotational work. 2. Increased fuel consumption: Modern vehicles' fuel injection is mostly controlled by the ECU, which increases fuel injection when it detects insufficient power. 3. Blue smoke from the exhaust: Overfilled oil may enter the combustion chamber and burn, resulting in thick blue smoke at the exhaust pipe outlet, causing air pollution and harming the environment. 4. Increased carbon deposits: Incompletely burned oil forms carbon deposits that adhere to components like the cylinder, combustion chamber, and valve group, increasing mechanical resistance and exacerbating power loss and higher fuel consumption. 5. Reduced mechanical lifespan: Increased resistance in components like pistons and the crankshaft, along with severe carbon buildup in parts like fuel injectors, lowers operational efficiency.
