Will Running a Car Out of Fuel Damage the Vehicle?

Running a car out of fuel may potentially damage the fuel pump. When the fuel warning light comes on, the vehicle can typically continue to drive for approximately 50 kilometers. However, it is advisable not to wait until the fuel warning light illuminates before refueling, as this can have certain negative effects on the vehicle. Additional information regarding vehicle usage is as follows: 1. During vehicle operation, it is essential not to wait until the fuel is completely depleted before refueling. When the fuel warning light activates, it indicates that the fuel pump is exposed above the fuel level. Since the fuel pump requires cooling during normal operation, which primarily relies on the gasoline in the fuel tank, the amount of heat the fuel can absorb is directly proportional to the volume of fuel in the tank. If the fuel level continues to decrease, it may damage the fuel pump and shorten its service life. 2. When refueling, avoid filling the tank to its maximum capacity, especially during hot summer conditions. This is because gasoline in the tank expands when heated and can evaporate into gasoline vapor. If there is insufficient space in the fuel tank to accommodate the vapor produced by the gasoline, it can not only lead to wastage but also contribute to environmental pollution and potentially increase the vehicle's fuel consumption.
I used to be an ordinary car enthusiast who loved studying automobiles. Running out of fuel can indeed damage your car, mainly because the fuel pump relies on gasoline for cooling and lubrication. When the tank is empty, the pump can overheat and fail, leading to costly and troublesome repairs. Another issue is that air can enter the fuel lines, making the engine hard to start or even causing permanent damage. Modern cars usually shut down automatically to prevent the worst-case scenario, but the risk remains. I recommend always keeping at least a quarter tank of fuel, especially avoiding driving too conservatively in extremely hot or cold weather, as it increases the likelihood of problems. By the way, replacing a fuel pump can cost hundreds of dollars, so it’s better to pay attention to the fuel gauge or set a phone reminder to refuel—it’s an easy way to prevent issues. In short, developing good habits can make your car more durable and save you unnecessary trouble.
When I was young, I drove too carelessly. Once, I ran out of gas completely and had to stop by the roadside. After being towed, the inspection revealed slight damage to the fuel pump, costing me a hefty repair bill. Now I know that running on empty can cause the fuel pump to overheat and burn out, and it may also allow impurities to enter and clog the system. Since then, I never slack off checking the fuel gauge and always refill when it reaches a quarter tank. A friend of mine had a similar experience, and the repair cost was enough to buy several tanks of fuel. Think about safety: stalling on the highway is extremely dangerous and can affect braking performance. I recommend forming a habit, like immediately looking for a gas station when the fuel light comes on, rather than waiting until the tank is empty. These experiences have taught me that prevention is a hundred times better than regret.
