How Long Can You Drive When the Fuel Tank is Empty?

Approximately 30-40 kilometers. When the fuel gauge light comes on, there are still 5-10 liters of fuel left in the tank, which varies slightly depending on the engine displacement and fuel tank size of different models. Precautions for refueling: Do not overfill the tank: It is important to note that overfilling the fuel tank can easily block the vent hole. Once the vent hole is blocked, the air pressure inside the tank will be lower than normal, leading to poor fuel supply or even a complete lack of fuel. Overfilling the tank also increases the vehicle's weight, thereby increasing fuel consumption. Over time, the fuel can deteriorate, posing a safety hazard. Refueling time: When the gauge shows one-quarter of the fuel remaining, it is time to refuel. It is best not to wait until the fuel gauge light comes on before refueling. Modern vehicles use electric fuel pumps that require fuel for lubrication and cooling. Frequently waiting until the fuel light comes on to refuel can prevent the fuel pump from receiving proper lubrication and cooling, ultimately reducing its lifespan.

Speaking about how far you can drive when the fuel tank is empty, I have to share some practical experience. When the low fuel warning light comes on, there's usually a small amount of fuel left in the tank, enough to keep the car running for several dozen kilometers. An average sedan can typically go 30 to 50 kilometers on city roads without issues, depending on your car's fuel consumption and driving habits. SUVs and off-road vehicles, which consume more fuel, might only make it about 20 kilometers before stalling. On highways, higher speeds lead to faster fuel consumption and shorter distances. But don't push your luck—running on empty can overheat and damage the fuel pump, which relies on gasoline for cooling. Repairs can cost at least a couple thousand yuan, not to mention the danger of suddenly stalling, especially at night, which can easily lead to accidents. My advice is to find a gas station as soon as the light comes on, and make it a habit to refuel when the tank is half empty—it's better for your car's longevity.

I often drive to and from work, and there have been a few times when the fuel gauge was almost empty, which made me a bit nervous. Based on experience, a small car in the city can still last for about 20 to 40 minutes, which translates to roughly 25 to 60 kilometers. But this isn't fixed—it depends on your car's age and brand. Older cars with aging fuel pumps might last even shorter, while newer cars with more sensitive sensors tend to be more accurate. Driving on mountain roads or in heavy traffic with frequent acceleration burns fuel faster, leaving you with even less remaining range. The risk is quite high—if the car stalls at a busy intersection, it's a hassle and requires calling a tow truck, costing both time and money. In daily life, I use a reminder app on my phone to plan the nearest gas station as soon as the fuel light comes on, which is both convenient and safer.

How far can you drive when the fuel tank is almost empty? Safety first, I think. On average, the vehicle can still run about 30 kilometers, but don't bet on it because the fuel level sensor might be inaccurate, leading to a shorter distance. The key point is that driving for too long can damage the engine and pump, and the repair costs are expensive. Moreover, stalling on the highway or during a rainy night has a high risk of accidents. It's better to pull over when the light comes on, use your phone to call for assistance, or walk to find a gas station to prevent issues. For peace of mind, set a navigation reminder to refuel when the tank is at a quarter full.
