How many liters of engine oil should be added to a BMW 525Li?

[DerekLee]

The BMW 525Li requires 6 liters of engine oil. Be careful not to add too much; the engine oil level should be maintained between the upper and lower marks on the dipstick for normal operation. Overfilling the engine oil will only lead to carbon buildup in the engine, which in turn increases fuel consumption. 1. How to check the engine oil level: Park the vehicle on a relatively level and flat surface. After 10 minutes, pull out the dipstick and observe the position of the oil between the upper and lower marks to determine whether the oil pan needs more oil. However, do not pull out the dipstick immediately after parking to check the oil level in the oil pan, as the result at this time will not accurately reflect the actual oil level. 2. Precautions: If the oil level in the oil pan is already below the lower mark on the dipstick, it is necessary to add oil promptly. First, unscrew the oil filler cap, then add an appropriate amount of the same brand and grade of oil as that in the oil pan. Wait for 10 minutes, then check whether the added oil meets the requirements. The oil level should be between the upper and middle marks on the dipstick.
