How many liters of engine oil does the BMW X4 require?

[LeJuliette]

The BMW X4 requires 4.5 liters of engine oil. Effects of overfilling engine oil: Overfilling engine oil can affect the operation of the three-way catalytic converter. Additionally, due to increased oil pressure, it may cause damage to sealing components. It also leads to excessive agitation of the crankshaft and connecting rod big ends during engine operation, which not only increases internal power loss but also results in more oil splashing onto the cylinder walls, potentially causing oil burning and exhaust smoke. Function of engine oil: The engine is the heart of a car, containing many metal surfaces that move against each other in friction. These components operate at high speeds in harsh environments, with working temperatures ranging from 400 to 600 degrees Celsius. Under such extreme conditions, only qualified lubricating oil can reduce wear on engine components and extend their service life.
