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

For a BMW 525, 5.5 liters of engine oil should be added. Engine oil is extremely important for a car's engine, often referred to as the lifeblood of the engine. Without engine oil, the engine cannot operate properly. Inside the engine, oil not only lubricates but also cleans, seals, cushions, prevents rust, and dissipates heat. The BMW 525 has dimensions of 5106mm in length, 1868mm in width, and 1500mm in height, with a wheelbase of 3105mm. It is a 4-door, 5-seater sedan equipped with an 8-speed automatic transmission, delivering a maximum power of 135kw and a maximum torque of 290nm.
I've been driving BMW series cars for over a decade, especially the 525 model, and how much engine oil to add is a common question. Based on my practical experience, the BMW 525 typically requires about 4.8 liters of oil, which includes the volume of the oil filter. Many car owners tend to overfill or underfill. For instance, I once accidentally added 5.2 liters, and the engine noise increased. Upon checking, I learned that excessive oil can increase internal pressure, potentially leading to seal damage or oil foaming. Conversely, adding too little, below 4.5 liters, can cause insufficient lubrication and accelerate component wear. I recommend following the manufacturer's manual precisely for oil measurement during each maintenance and checking the oil level with the dipstick when the engine is cold, ensuring it's between the Min and Max lines. Regular oil changes every 5,000 kilometers help maintain engine efficiency and prolong the car's lifespan. BMW engines are ingeniously designed, but maintenance should never be taken lightly.
