Is the fuel consumption for the first tank of gas in a new car particularly high?

[EllianaRose]

New cars tend to have relatively higher fuel consumption for the first tank of gas. Parts break-in: The fuel consumption listed in the specifications is the ideal fuel consumption, obtained under ideal conditions. A new car needs a break-in period because the parts of a brand-new car are not perfectly smooth. Only after the parts have worn in against each other can they become completely smooth. During this process, the car has to increase engine power to overcome the resistance between parts, naturally resulting in higher fuel consumption. Improper driving: If you frequently floor the accelerator or brake hard during driving, it will increase the car's fuel consumption. Additionally, maintaining an appropriate following distance from the car ahead can help reduce unnecessary braking.
