How much engine oil does a BMW X1 need at one time?

[DelAngela]

BMW X1 requires approximately 4.8L of engine oil at one time. The following are the related introductions of engine oil: 1. Reduce wear: There is rapid relative sliding between the piston and cylinder, as well as between the main shaft and bearing shells. To prevent excessive wear of parts, an oil film of sufficient thickness needs to be established between the two sliding surfaces to separate the relatively sliding parts, reducing wear and extending mechanical life. 2. Cooling: Engine oil helps the radiator cool the engine and expels heat from the engine. 3. Sealing and leakage prevention: Engine oil can form a sealing ring between the piston ring and piston, reducing gas leakage and the entry of pollutants. 4. Shock absorption and buffering: When the pressure at the engine cylinder port rises sharply, suddenly increasing the load on the piston, piston chips, connecting rod, and crankshaft bearings, this load is transmitted and lubricated through the bearings, allowing the impact load to be buffered.
