When the fuel gauge shows 0 kilometers and the warning light comes on, it is just a reminder to refuel. In fact, there is still fuel left in the tank. Generally, most household cars can still run for at least 20 to 30 kilometers without any issues. However, the exact distance you can drive depends on the specific model, as the size of the fuel tank, fuel consumption, and settings vary for each vehicle. Remaining Fuel When the Warning Light Comes On: Normally, when the fuel gauge warning light illuminates, an average household sedan still has about 5 liters of fuel left. The exact remaining fuel quantity can be found in the vehicle's user manual. Emergency Measures When the Warning Light Comes On: Factors such as the driver's skills, road conditions, and weather can affect fuel consumption. If the fuel gauge warning light comes on while driving on a highway, try to maintain a steady speed in the right lane. It is also recommended to turn off the air conditioning to maximize fuel efficiency.

How far can you drive when the fuel gauge shows zero? Once on the highway, I drove 25 km after it hit zero to find a gas station. My car is a family SUV, and I drove smoothly without sudden acceleration—luckily, nothing went wrong. A friend with the same model car stalled in less than 10 km, damaging the fuel pump. Generally, you can drive 10-50 km after the gauge shows zero, depending on the car: older models or those with a reserve fuel buffer in the tank design may go farther, while newer cars with accurate sensors pose higher risks. Road conditions and driving style matter a lot: fast highway driving consumes more fuel, reducing the distance, while slow city driving saves some; steep uphill burns fuel quickly, while downhill may conserve it. It's best not to test it—develop a habit of refueling when the gauge hits a quarter to avoid overheating and costly fuel pump repairs.

I've always been curious about the truth behind those numbers when driving. Displaying zero kilometers is actually a buffer estimated by the system, and most cars can still run about 20 kilometers. I've tested it by connecting my phone app to the car's system, and the remaining fuel error was around 10%. Driving on urban roads at 40 kilometers per hour, it can last 15-20 kilometers without issue. However, if the sensor is misplaced or the car is old, it might really stop. Driving habits are crucial: aggressive acceleration burns fuel quickly, while smooth driving saves distance; vehicle load also matters, as an empty car consumes less fuel. Overall, don't take risks when the display shows zero—refuel as soon as possible to avoid breaking down mid-journey and compromising safety.

Displaying zero kilometers means you should stop driving immediately. I always remind myself it's too dangerous. The fuel pump relies on gasoline for cooling; running empty can cause overheating and damage, costing hundreds in repairs. The engine sucking in air due to lack of fuel also harms components. I never drive with less than half a tank and refuel as soon as the light comes on. If it truly shows zero, pull over, turn off the engine, and call for a tow or have a friend bring fuel. Each car varies greatly: in the city, you might manage 10 km, less on highways. Develop the habit of planning routes and gas stations in advance.
