What is the fuel tank capacity of the BMW 3 Series 320Li?

The fuel tank capacity of the BMW 320 is 59 liters, as officially announced. The BMW 320 requires 95-octane fuel, with a fuel consumption of 6.1-6.9L per 100 kilometers. A full tank can cover a distance of 855-967km. During daily driving, it is essential to monitor the remaining fuel level in the tank. This is typically done by observing the fuel gauge inside the vehicle. If there are no other issues, the fuel level will be accurately reflected on the gauge. The fuel gauge usually has 5 to 6 segments. It is advisable to refuel when there are only 2 segments left to avoid running out of fuel mid-journey. During actual refueling, the amount of fuel may exceed the marked capacity. This is because the fuel tank capacity specified by the manufacturer is measured from the bottom of the tank to the safety limit, and there is additional space from the safety limit to the tank opening. This space is reserved to allow for fuel expansion due to temperature increases without causing overflow. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the marked tank capacity.
I previously drove a BMW 3 Series 320Li, which has a fuel tank capacity of 59 liters. This size is quite practical for daily driving, providing a long range with an average fuel consumption of around 7 liters per 100 kilometers. A full tank can cover over 800 kilometers, meaning you rarely need to refuel on highways. The fuel tank is positioned near the rear axle, helping to balance the vehicle's weight and improve driving stability. When refueling, 92-octane gasoline is sufficient—cost-effective and efficient. I've noticed that fuel tank size directly impacts convenience; the 59-liter capacity is slightly larger than the Audi A4L's (58 liters) in the same class, making it more suitable for frequent long-distance travel. During regular maintenance, don’t forget to check the fuel pump and fuel lines to prevent malfunctions. Overall, the 59-liter fuel tank makes travel more worry-free.
