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

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.
When I bought the car, I noticed the first tank of fuel was consumed more than I expected, significantly higher than anticipated. This is mainly because the engine of a new car is still in the break-in period. The parts are freshly assembled, leading to greater friction and less smooth operation, which results in slightly higher fuel consumption. Additionally, the fuel system and sensors need time to adapt when the car is new, so fuel efficiency might be lower initially. Moreover, we often get too excited driving a new car, stepping hard on the accelerator or testing features like the air conditioning, which consumes more fuel. However, don’t worry too much—this situation usually only lasts for the first tank or the first few hundred kilometers. After that, fuel consumption will gradually decrease. It’s recommended to drive gently during the break-in period, avoid sudden acceleration, and regularly check tire pressure and engine oil conditions to help return to normal more quickly.
The first tank of fuel consumption for a new car tends to be higher, which I’ve personally experienced—it feels like the fuel tank empties in no time. This is mostly due to driving habits: new car owners often itch to test rapid acceleration or high-speed driving, which increases engine load and fuel consumption. Additionally, new components like the drivetrain or transmission are still in the break-in period, operating less efficiently. Environmental factors also play a key role; frequent city traffic or heavy AC usage will naturally spike fuel consumption. However, this isn’t a major issue—after one or two tanks, it stabilizes. We can track fuel consumption changes, use a mobile app to monitor data, and develop smooth acceleration habits to avoid turning the new car into a gas guzzler.
The first tank of fuel consumption is often higher after buying a new car, an experience shared by some owners. Increased friction in new engine components and higher initial operating resistance lead to more fuel consumption; sensor calibration can also affect accurate measurement. Driving habits such as frequent starts and stops or using air conditioning add to the burden. This situation is not permanent—as mileage accumulates, fuel consumption gradually normalizes, and highway driving can even accelerate the break-in process.
