How far can a car go on the last bar of fuel?

Each vehicle has a different fuel tank capacity, and typically when only one bar of fuel remains, it can still travel over 100 kilometers. Here is some relevant information about fuel tank maintenance: 1. Regularly clean the fuel system: The fuel tank provides waterproofing and insulation. If the car idles for long periods, the fuel system should be cleaned or the filter replaced at 30,000 kilometers. Otherwise, the fuel system may become clogged, increasing the tank's air pressure. This can cause the car to shake while driving. Due to the high pressure, the fuel tank is prone to cracking, and in severe cases, fuel leakage may occur, increasing fuel consumption. 2. Tighten the fuel cap: In summer, temperatures are high, and fuel and water evaporate quickly. Make sure to tighten the fuel cap to prevent fuel line leaks. Also, regularly check the water level in the radiator, the oil level in the crankcase, the brake fluid level in the master cylinder, and the electrolyte density and level in the battery. If any of these levels fall below the normal range, remember to add or adjust them promptly.
Since my first car twenty years ago, I've often encountered the fuel light coming on, and usually it can last for about forty to fifty kilometers. My small-displacement sedan once made it sixty kilometers on the highway at most. But it all depends on how you drive—more uphill driving, blasting the AC, or sudden braking burns fuel faster, and you might only get twenty kilometers. I remember once being stuck in traffic in the suburbs when the light came on, and I rushed to refuel, saving myself the tow truck fee. I suggest everyone develop the habit of refueling when a quarter tank remains—don’t gamble on the last bit of fuel to avoid the hassle of breaking down. Different types of cars vary quite a bit; for example, SUVs usually run about ten kilometers less than small cars. After driving for so many years, I’ve learned to be wiser—it saves both peace of mind and money.
When the car's fuel light comes on, it indicates you can still drive for a distance, typically around 30 to 50 kilometers in the city, and possibly up to 60 kilometers on the highway. Calculating it is quite simple: divide the remaining fuel in the tank by the average fuel consumption. For example, most cars have about 7 to 8 liters left, and with a fuel consumption of 7 to 8 liters per 100 kilometers, that would be roughly 100 kilometers? Wait, no—it's the remaining fuel divided by the fuel consumption, then multiplied by 100 to get the remaining distance. However, real-world conditions are much more variable—frequent stops and starts in the city, heavy loads, or low tire pressure can all reduce this distance. The type of vehicle also plays a big role: small cars are more fuel-efficient and can go farther, while larger vehicles consume fuel faster. I always remind my friends not to rely too much on this estimate and to refuel as soon as possible to avoid unexpected breakdowns on the road.
