How many kilometers can you drive when the fuel level is low to the reserve level?

When the dashboard indicates that the fuel level is low to the reserve level, there is approximately 10% of the tank capacity remaining, which varies by vehicle model, typically between 6-14 liters. Smaller vehicles generally have smaller fuel tanks, so the reserve fuel quantity is also less, but their fuel consumption is relatively lower. The reserve fuel can usually cover about 80 kilometers. Considering factors such as driving habits, road conditions, and vehicle condition, a conservative estimate would be around 50 kilometers. Of course, the exact distance depends on your usual fuel consumption. More details about gasoline vehicle fuel consumption are as follows: 1. When the fuel gauge light comes on, you can only drive about 20 kilometers, and you must find a gas station to refuel within this distance. 2. If you run out of fuel and the car stops, even if you refuel, it may not start the engine. The reasons are as follows: (1) The remaining fuel at the bottom of the tank is relatively dirty, and some tanks may contain rust or rusty water, which can easily damage the fuel pump. (2) If the fuel in the tank is completely used up, the fuel pump lacks fuel for cooling and lubrication, making it prone to burning out.
I remember the remaining mileage after the fuel gauge hits the reserve point can vary significantly. Years of driving experience tell me this depends on the vehicle model and driving habits. For regular sedans, the reserve fuel capacity is typically 5-10 liters. With a fuel consumption of 8-10L/100km, that translates to 50-100km of range. My old Ford once managed 60km on reserve in real-world testing, but during a mountainous drive with frequent climbs, it stalled after just 30km. Newer vehicles like hybrids might show longer reserves, with displays indicating 80km. Don't rely on this though - the fuel pump relies on gasoline for cooling, and driving on empty risks component damage. Plus, poor road conditions or AC usage will reduce the distance. General advice: refuel when the light comes on to avoid unnecessary risks.
As a car enthusiast who loves studying vehicles, I'll do the math: the reserve fuel level corresponds to approximately 10% of the remaining fuel in the tank. For example, a 50L tank would have about 5L left. Assuming a fuel consumption of 9L/100km, theoretically it can run 55 kilometers. In actual driving tests with my own car: maintaining steady speed on highways with minimal air conditioning usage, I've achieved up to 70 kilometers; with rapid acceleration or full load, it only runs 40 kilometers. Vehicle weight, tire pressure, and road conditions all affect fuel consumption; lightweight electric vehicles have longer range, while SUVs consume fuel faster and reduce distance. Most manufacturers design the reserve to cover an average distance of 50-80 kilometers, but it's better to refuel early to protect the engine.
