How many kilometers can you drive when the fuel tank reaches the yellow warning light?

Generally, after the fuel tank warning light turns yellow, fuel-efficient vehicles can travel about 40 kilometers, while high-consumption vehicles may only manage around 20 kilometers. It's crucial to refuel promptly when the warning light activates. Insufficient fuel exposes the fuel pump, which relies on gasoline for cooling. Driving tips after the yellow warning light appears are as follows: 1. Maintain economical speed: Control your vehicle's speed appropriately and head to a gas station immediately. For 1.3L to 1.8L displacement vehicles, the most fuel-efficient speed ranges between 45-60 km/h. On highways, avoid driving too slowly while minimizing braking. If necessary, pull over safely, activate hazard lights, and call for assistance. 2. Turn off electrical devices: Operating air conditioning reduces engine power significantly as it increases load - the engine must simultaneously power the vehicle, AC compressor, and alternator. When fuel is low, deactivate AC and other high-power-consuming devices to conserve fuel.
I've driven no less than ten car models, and the yellow fuel light situation really depends on the vehicle. Take my BMW 3 Series for example - after the yellow light came on, I drove 70 km before refueling, with the dashboard showing 20 km remaining. But when I drove my friend's Corolla last time, it completely stalled after just 55 km with the light on. I recommend treating 60 km as the safety margin, especially on highways. The key is knowing how to read instant fuel consumption - releasing the throttle downhill to make the range number increase can genuinely buy you an extra 7-8 km. Remember to refuel as soon as the yellow light comes on; waiting until the needle hits bottom is terrible for the fuel pump.
