What is the fuel tank capacity of the BMW 525 in liters?

The fuel tank capacity of the BMW 525 is 68 liters, as officially announced by the manufacturer. The BMW 525 requires 95-octane fuel, with a fuel consumption of 6.5-7.2L per 100 kilometers. A full tank can cover a distance of 944-1046km. During daily driving, it is essential to monitor the remaining fuel level in the tank. This is typically observed through the fuel gauge inside the vehicle. Under normal circumstances, the fuel level will be accurately reflected on the gauge. The fuel gauge usually has 5 to 6 segments, and it is advisable to refuel when only 2 segments remain to avoid running out of fuel mid-journey. In actual refueling situations, the amount of fuel added may exceed the marked capacity. This is because the manufacturer's specified tank capacity is measured from the bottom of the tank to the safety limit. There is additional space from the safety limit to the tank opening, which is designed to accommodate fuel expansion due to temperature increases without causing overflow. If fuel is added up to the tank opening during refueling, the actual amount of fuel added may exceed the marked tank capacity.
The fuel tank capacity of the BMW 525 is approximately 68 liters, depending on the specific model year, but it generally falls within this range. I've researched quite a few BMW models, and the standard 525Li version typically has this size. This design is quite practical because with a full 68-liter tank, under mixed driving conditions and an average fuel consumption of 8L/100km, it can cover over 700 kilometers. It's slightly smaller than the Audi A6's 73-liter tank but sufficient for daily commuting. From my driving experience, a larger tank reduces refueling frequency, which is especially convenient on highways. However, when the tank is full, the increased vehicle weight leads to slightly higher fuel consumption, so designers must have balanced this trade-off. The tank material is also important—BMW uses high-strength plastic, which is corrosion-resistant and leak-proof, making it better for long-term maintenance.
