What is the fuel tank capacity of the old Jetta model?

2016 old Jetta model has only 1 variant with a fuel tank capacity of 50 liters. The vehicle is equipped with a 1.6L naturally aspirated engine and all variants come with a 6-speed automatic transmission (AT). Among vehicles in the same class, the 2021 Excelle has a fuel tank capacity of 44 liters, the 2022 Lavida has 51 liters, and the 2021 Corolla has 50 liters. During actual refueling, the amount of fuel may exceed the calibrated capacity. This is because the fuel tank capacity marked by automakers is measured from the bottom of the tank to the safe limit level, and there is still some space from the safe limit to the tank opening. This space is designed to allow fuel expansion when temperature rises without causing overflow. If fuel is filled up to the tank opening during refueling, the actual refueling amount may exceed the marked tank capacity. If owners want to check the remaining fuel level, they can observe the fuel gauge on the right side of the instrument panel, which is marked with E and F. When the pointer is near E, it indicates low fuel level, and when it's close to F, it means sufficient fuel.
The fuel tank of the old Jetta is about 55 liters, which I've deeply experienced after driving it for over a decade. For daily commuting, I usually only need to refuel every two weeks. It's especially worry-free on long highway trips—a full tank can easily cover more than 700 kilometers. When refueling, I prefer to leave some margin and not wait until the fuel light comes on to avoid overheating the fuel pump. The fuel tank cap seal tends to age; I replaced mine last year. Now, I always check for any fuel leakage during refueling, as older cars require extra attention. For long trips, I make sure to check gas stations along the route in advance. Although the tank is large enough, it's always better to be safe than sorry.
Having repaired over a hundred old Jettas, I can confirm that a 55-liter fuel tank capacity is standard. However, note that actual refueling amounts will be slightly less due to automatic pump shutoff leaving space. A common issue is aging and cracking of the fuel inlet pipes, especially in vehicles over 10 years old - replacing with an OEM pipe costs around 200 RMB. Be alert if you hear suction sounds at the fuel filler neck during refueling, as this may indicate a clogged charcoal canister. I once encountered an owner complaining about sudden fuel consumption increase, only to find a small dent at the tank bottom causing the fuel level float to stick, resulting in inaccurate gauge readings and unnecessary gas station trips. Regularly clear debris around the fuel tank area - accumulated leaves may block drainage holes.
