You should refuel when the remaining range is 140 kilometers. The mileage indication on the fuel gauge is not always accurate. While you can typically drive a few dozen kilometers after the low fuel warning, it's best to fill up the tank. Here are some details about driving range: Driving Range: Driving range, also referred to as endurance, is the total distance a vehicle such as a car or ship can travel continuously with its maximum fuel reserve. For electric vehicles, the driving range is the distance traveled from a fully charged state until the test conditions specified by the standard are met. It is an important economic indicator for electric vehicles. New Energy Vehicle Driving Range: This refers to the distance a vehicle can travel on a single full charge under ideal road conditions, wind speed, temperature, etc., at a constant speed. Hybrid vehicles and lead-acid battery vehicles (low-speed vehicles) generally have a shorter driving range.

Having driven for over twenty years, I recommend finding a gas station when the remaining range drops below 200 kilometers. Every driver knows that the range displayed by the onboard computer isn’t accurate—traffic jams and detours can significantly reduce the actual mileage. Using air conditioning in summer increases fuel consumption, while heating in winter also adds to energy usage, potentially leaving you with less than 100 kilometers of actual range. Gas stations are spaced far apart on highways, and missing one can be troublesome. Running the fuel tank too low damages the fuel pump, and repairs can cost hundreds. The most hassle-free approach is to fill up whenever you pass a convenient gas station—don’t wait until the warning light comes on to panic.

As someone who is usually thrifty, I don't worry about the 140 km range in the city, but I immediately refuel when driving in the suburbs or on long trips. Checking the mobile map for gas stations with discount activities along the way can save me dozens of yuan. It's best not to fill the tank too full; half a tank is ideal to avoid adding extra weight and consuming more fuel. However, keeping the fuel level too low can damage the fuel pump, so I make it a habit to refuel when there's about 100 km of range left. Regularly replacing the fuel filter also helps with protection. Overall, this approach is the most economical.

Seven or eight years of experience driving on highways have taught me that I must refuel when the remaining range is 140 kilometers. The distance between service areas is generally at least 40 to 50 kilometers, and it would be terrible if one were temporarily closed. The actual fuel consumption at high speeds is 20% higher than what the gauge shows, and it drops even faster with the air conditioning on. Last week, I saw a car stranded on the emergency lane with my own eyes—the cost of the rescue tow truck would have covered half a year's worth of fuel. So now I've developed a habit: when the remaining range drops below 200 kilometers, I pull into a service area. Filling up the tank also gives me a chance to stretch my legs.
