How many kilometers can you drive with one bar of fuel left in the car?

When there is one bar of fuel left in the car, it can generally travel an additional 40-50 kilometers, but the range may vary depending on the vehicle model. It is recommended to carefully check the owner's manual. Below are some precautions regarding the fuel gauge: 1. Do not wait until the warning light comes on to refuel: Since the fuel pump is located inside the fuel tank and relies on gasoline for cooling and lubrication, insufficient fuel can impair the pump's normal operation and reduce its lifespan. 2. It is not advisable to fill the tank completely: Gasoline expands when heated and evaporates into gasoline vapor under high summer temperatures, requiring space to accommodate this. If the tank is overfilled without any space left, gasoline vapor or even liquid gasoline may enter the carbon canister for storage. Once the carbon canister is full, the excess will escape into the air, resulting in both waste and environmental pollution.
I've been driving for over a decade, and how far you can go on one fuel gauge segment depends on the car model and road conditions. For a typical sedan with about a 50-liter fuel tank divided into 4-8 segments, one segment may correspond to 5-10 liters of fuel. With an average fuel consumption of 10 liters per 100 km, you can roughly travel 50-100 km per segment. But don't be too optimistic—the fuel gauge isn't always accurate. Once on a long trip, I had one segment left but only made it 70 km before the warning light came on. Luckily, there was a gas station nearby. In city traffic with higher fuel consumption, you won't get as far. My advice: refuel when you're down to one segment—don't push your luck. Also, driving habits make a big difference; smooth acceleration saves fuel. Overall, this is just a rough estimate, and it varies by driver.
