How Many Kilometers Can a Car Run on 15 Liters of Gasoline?

If driving on general urban roads, 15 liters of gasoline can approximately cover a distance of 187.5 kilometers. Here are some fuel-saving tips for cars: 1. Avoid stepping hard on the accelerator when starting or accelerating suddenly: Accelerating a car to a certain speed requires burning gasoline to generate kinetic energy. When starting with a hard press on the accelerator, the car needs more kinetic energy, and the engine consumes more fuel. Similarly, pressing the accelerator evenly can significantly reduce gasoline injection and fuel consumption. 2. Maintain a reasonable driving speed: The best fuel-saving state for a car is driving at a constant speed. Generally, for small-displacement models below 1.6L, a speed of 60-80km/h is more fuel-efficient, while for models above 1.8L, a speed of 80-100km/h is more fuel-efficient. If there are no speed requirements on the road, try to drive at a constant speed within the above ranges. 3. Minimize sudden braking: Encountering traffic lights or obstacles on the road and braking suddenly will waste the kinetic energy produced by the gasoline engine, increasing fuel consumption. 4. Avoid prolonged engine idling: The fuel consumption during engine idling is greater than during normal driving. 5. Pay attention to tire maintenance: Check tire wear. If the wear is severe or small stones are embedded in the tires, driving resistance will increase. Also, check tire pressure. If the tire pressure drops, the car will lack power when starting and accelerating, and fuel consumption will increase.
I drive a compact car, usually cruising around the city with a fuel consumption of about 7 liters per 100 kilometers. Recently, I added 15 liters of fuel specifically to test how far I could go. In stop-and-go city traffic, I managed to drive about 210 kilometers, which isn't very far; but on the highway, maintaining a steady speed, I drove nearly 300 kilometers. I remember last year when I took a long trip to a neighboring province, the same 15 liters of fuel surprisingly got me over 280 kilometers—good road conditions really save fuel. I think there are quite a few influencing factors, like how driving aggressively uses more fuel with frequent throttle inputs, while smooth acceleration can extend the distance. Also, the condition of the car is crucial; regular maintenance keeps the engine efficient, and properly inflated tires can reduce fuel consumption. If you want to estimate, I suggest checking your car's manual for fuel consumption data first, then adjusting slightly based on current road conditions. Paying attention to these details usually saves me a good amount on fuel costs.
I used to take my kids out often, now driving a family SUV with heavier passenger and cargo loads, the fuel consumption is slightly higher, about 9 liters per 100 kilometers. With 15 liters of gasoline, I've actually tested it on weekend outings—in the city, it's around 170 kilometers, and on the highway, it can reach 220 kilometers. I remember one winter when I turned on the heater, the fuel consumption shot up, and 15 liters only got me 150 kilometers—what a waste. Bigger cars consume more fuel than smaller ones, larger engine displacement uses more gas, and steep roads also waste fuel. I've picked up some fuel-saving tips: avoid sudden braking and acceleration, maintain a steady speed, and clean out the trunk to reduce weight. Using air conditioning in summer also consumes fuel, so I try to open the windows when possible. I think figuring out fuel consumption is all about trial and error, but safety comes first—don't drive too dangerously just to save fuel.
