How much engine oil should be added to a BMW 525?

For a BMW 525, adding 5.5 liters of engine oil during each maintenance service is sufficient. Engine oil is extremely crucial for a car's engine, often referred to as the 'blood' of the engine. Without engine oil, the engine cannot function properly. Engine oil serves multiple purposes within the engine, including lubrication, cleaning, sealing, cushioning, rust prevention, and heat dissipation. Here are some key points to note when changing engine oil: 1. Drain the oil when it's warm: The oil flows better when warm, allowing it to drain more effectively from the oil holes, but be cautious not to overheat it to avoid burns. 2. Fill to the dipstick mark: The amount of oil added should be strictly controlled between the lower and upper marks on the dipstick. 3. Choose the oil change interval based on factors such as vehicle condition, road conditions, oil quality, and driving habits. 4. Select the oil grade according to the driving environment, driving frequency, and the engine's specific requirements—preferably higher rather than lower. 5. Do not substitute winter oil for summer oil or vice versa; change the oil when seasons change. Additionally, diesel and gasoline engine oils must not be mixed and should be strictly differentiated.
I've been driving a BMW 525 for some time now, and I remember that each oil change during maintenance uses about 6 to 6.5 liters. The exact amount depends on the engine condition, and mine usually takes around 6.5 liters. The mechanics often recommend 5W-30 oil because this type is suitable for BMW engines. When adding oil, don't rush; let the car cool down first before checking the dipstick to ensure the oil level stays between the max and min lines. Adding too much oil can increase engine pressure, leading to leaks or oil burning, while adding too little can affect lubrication. I personally check the oil every 5,000 kilometers or so and take the opportunity to see if the oil filter needs replacing. Developing this habit can extend the life of your beloved car—don't wait until the warning light comes on. After driving for a long time, I've realized that details make all the difference, and regular maintenance doesn't take much time.
