How many liters of oil does a BMW 525 need?

[DelGriffin]

BMW 525 requires 6.5 liters of oil. The following are precautions when changing the oil: 1. Drain the oil when it is hot. At this time, the fluidity is better, and it can flow out of the oil hole more easily, but be careful not to overheat to avoid scalding. 2. Fill to the mark. The amount of oil added should be strictly controlled between the lower and upper marks on the oil dipstick. 3. The oil change cycle should be selected based on the vehicle condition, road conditions, oil quality, and driving habits. 4. The oil should be selected according to the driving environment, driving frequency, and the requirements of the vehicle engine itself. It is better to choose a higher grade than a lower one. 5. Winter and summer oils cannot be substituted for each other. Oil must be changed when the season changes. Diesel and gasoline oils cannot be mixed and should be strictly distinguished. 6. Use of additives. Common oil additives mainly include antioxidants, anti-wear agents, detergents, dispersants, foam inhibitors, anti-corrosion and rust inhibitors, etc. In fact, finished oils already contain these components in a certain proportion. Unless you are a professional, try not to arbitrarily change the oil ratio to avoid unpredictable consequences or losses.
