Can a Car Still Run Without Fuel?

When the fuel gauge indicates empty, a car can typically continue to drive for approximately 70 kilometers. Below are specific details about a car's fuel tank: Marked capacity is the safe volume: The volume marked on most fuel tanks represents the safe capacity, which is generally about 10% less than the actual capacity. During the design of the fuel tank, considering the thermal expansion and contraction characteristics of fuel, a certain amount of space must be left inside the tank after filling to the rated volume to prevent excessive internal pressure and ensure driving safety. Fuel gauge cannot accurately reflect fuel level: It is not possible to precisely determine the remaining fuel based solely on the fuel gauge on the dashboard, as it provides a qualitative indication rather than a quantitative measurement of the fuel in the tank.
A car without fuel simply won't move. Having driven older cars for years, I've personally experienced this several times. The engine runs on fuel, and without the fuel pump delivering it to the cylinders, the machine stops, and the car shuts down directly. Unlike electric vehicles that have backup batteries, gasoline cars don't have that luxury. The fuel system's pump will use up the last bit of fuel but won't get you far. Typically, when the fuel gauge is near zero, the engine might shudder once before coming to a halt. At this point, all you can do is pull over, turn on the hazard lights, and call for a tow truck or a friend with a fuel can to come to the rescue. So, make it a habit to check the fuel gauge needle before driving—don't wait until the warning light comes on to start worrying. I remember once forgetting to refuel during a trip and breaking down halfway, almost causing a major inconvenience. Since then, I've made it a point to check the fuel level regularly.
As a novice driver, I panicked the first time I ran out of fuel. I usually didn't pay attention to the fuel gauge, and after driving about ten kilometers, the dashboard light came on, the car started shaking, and slowly came to a stop. An engine without fuel is like a person without food—it can't move. Fuel is used for combustion to generate power; with an empty tank, you can't do anything but stop. Luckily, I called for roadside assistance. The mechanic said gasoline cars can't move at all without fuel, and it's best to refill regularly to avoid trouble. Now I've learned my lesson—I glance at the fuel level before every trip and keep at least half a tank to stay worry-free and avoid awkward situations.
