How much engine oil should be added to the BMW N52B25 engine?

BMW N52 engine requires 7L of engine oil. Oil consumption issue: Since BMW engines generally have higher oil consumption, the 6-cylinder engines designed for these vehicles require 7 liters of oil. When adding oil, it is crucial not to go below the middle mark. The ideal oil level is between the upper and lower marks on the dipstick. Engine: An engine (Engine) is a machine capable of converting other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. For example, internal combustion engines typically convert chemical energy into mechanical energy. The term "engine" can refer to both the power-generating device and the entire machine that includes the power unit (e.g., gasoline engines, aircraft engines). The engine was first developed in the UK, so the concept of an engine originates from English, with its original meaning referring to "a mechanical device that generates power."
After repairing BMW engines for so many years, I can tell you that the N52B25 model typically requires around 6.5 liters of oil, with slight adjustments based on your car's year. Don't fill it all at once to avoid leaks. I recommend full synthetic 5W-30 oil for better flow and engine protection—I've had good results with Mobil. When changing the oil yourself, start the car for a few minutes to warm it up, then let the oil cool slightly before draining it completely by loosening the oil pan screw. Check the dipstick before adding new oil—aim for the middle mark to avoid overfilling, which increases friction and oil burning. Change the oil every 8,000 to 10,000 kilometers and replace the filter to extend engine life and save on repairs. After adding oil, start the car for a few minutes and recheck the level—it's safe, simple, and works for older cars too.
