Why does the range decrease after refueling?

[MacRobert]

After refueling, the decrease in range indicates an increase in fuel consumption per 100 kilometers. The following is a relevant introduction about the range: 1. Concept: The driving range, also known as endurance, refers to the total distance that vehicles such as cars and ships can travel continuously with the maximum fuel reserve. For electric vehicles, the driving range refers to the distance traveled from a fully charged state of the power battery to the end of the test under standard conditions, which is an important economic indicator for electric vehicles. 2. Continuous driving range: The continuous driving range of a car with a full fuel tank under certain road conditions, generally 300 to 500 kilometers for ordinary vehicles, while military vehicles usually achieve 600 to 800 kilometers. For new energy vehicles, the driving range refers to the distance traveled at a constant speed under ideal road conditions, wind speed, temperature, etc., after a full charge. Hybrid vehicles and lead-acid battery vehicles (low-speed vehicles) generally have a relatively shorter driving range.
