How many liters of engine oil does a BMW X1 require?

[StWalker]

BMW X1 maintenance typically requires 4.5L of engine oil. Introduction to engine oil: Engine oil is as vital to an engine as blood is to the heart. The engine is the heart of a car, containing many metal surfaces that rub against each other during operation. These components move at high speeds in harsh environments, with working temperatures reaching 400 to 600 degrees Celsius. Under such extreme conditions, only qualified lubricating oil can reduce wear on engine parts and extend their service life. Reducing wear: There is rapid relative sliding between the piston and cylinder, as well as between the main shaft and bearing bush. To prevent excessive wear on these parts, an oil film must be established between the sliding surfaces. A sufficiently thick oil film separates the surfaces of the relatively sliding parts, thereby achieving the goal of reducing wear. Engine oil also helps cool the engine by carrying heat back to the oil tank, which then dissipates into the air via the radiator.
