Where is the car's fuel tank located?

Most vehicle models have their fuel tanks positioned towards the rear underside of the car, while some models place the tank in the middle underside. Taking the Buick Excelle as an example, the fuel tank release button is located at the bottom left side of the driver's seat. Lift it upwards and release to open the fuel filler cap. The Buick Excelle's fuel gauge consists of eight segments, and the fuel tank capacity is 44 liters. If the fuel level is too low, the fuel control indicator will illuminate. If this indicator flashes, refuel immediately and avoid running the tank completely dry. Below is an introduction to the vehicle's fuel system: 1. Before refueling, turn off the engine and ensure all doors and windows are closed. The fuel type is unleaded gasoline, with ethanol-blended gasoline containing up to 10% ethanol allowed. 2. The fuel type is unleaded gasoline with an octane rating of 92 or higher. Ethanol-blended gasoline with up to 10% ethanol is permissible, but ensure the octane rating of the ethanol-blended gasoline meets the aforementioned standard. 3. Frequently mixing gasoline from Sinopec and PetroChina, two major brands, can lead to carbon buildup and reduced engine performance due to differences in their refining processes, standards, and additives.

People used to always ask me where the fuel tank is located. As someone who has driven for decades, here’s a tip: in most cars, it’s hidden under the rear seat. Lift the rear seat cushion, and you’ll feel the metal protective casing. Interestingly, older cars often placed the fuel tank at the rear, but for safety reasons, modern cars have moved it in front of the rear axle. When the fuel gauge lights up red, remember that the fuel filler cap is usually on the side of the car—often on the right rear side for left-hand-drive vehicles, with European cars being the exception. If you’re unsure, check the small triangular arrow next to the fuel tank icon on the dashboard: an arrow pointing left means the filler is on the left—a must-know trick for beginners.

As a mom who often drives with kids, I'll teach you a quick way to locate the fuel tank: Before each refueling, checking the fuel gun position in the rearview mirror is the most intuitive method. Most family cars have the fuel filler on the right rear side, like my SUV which has it designed above the right rear wheel. Once when rushing to take my child to school, I couldn't find the fuel filler in a friend's car and got really anxious - later I discovered Japanese cars often place it on the left side. Now I always check the fuel tank symbol with its small arrow near the door before getting in - that little arrow is super practical. A gas station attendant told me sedan fuel tanks are generally at the bottom rear of the vehicle, while hatchbacks are special with theirs located below the spare tire position.

The placement of the fuel tank in vehicle engineering is highly deliberate. Mainstream designs position the fuel tank ahead of the rear axle, utilizing the exhaust pipe and chassis frame to form a protective zone. Taking the Passat as an example, engineers embedded the 66-liter fuel tank beneath the rear seat footwell—this central layout enhances crash safety. Off-road vehicles differ; the Wrangler mounts its fuel tank directly on the side of the frame. During gas station construction, I've seen taxis with rear seats removed, revealing the fuel tank as a silver metal box nestled in the center of the undercarriage. Industry convention places the inspection port inside the right rear wheel arch—when refueling, be careful not to let the nozzle hit the fill limiter valve.
