Is Fuel Consumption Higher During the Break-in Period or After the Break-in Period?

[McGabrielle]

Fuel consumption is higher during the car break-in period. Fuel consumption during the break-in period: Before the break-in, the coordination between various components is not as smooth, and the frictional resistance is relatively high, which naturally leads to slightly higher fuel consumption. The engine, transmission, and drivetrain—any component with resistance can contribute to higher fuel consumption, and all these parts require a break-in period. Normal fuel consumption: After the break-in, the frictional resistance of the components decreases, and operation becomes smoother, resulting in a slight reduction in fuel consumption. The fuel consumption of motor vehicles is considered normal if it matches the Ministry of Industry and Information Technology's (MIIT) standard fuel consumption per 100 kilometers or is 3 to 5 points higher. The MIIT fuel consumption is marked on the vehicle, typically as a yellow label on the windshield, and can serve as a reference. Different driving habits and usage locations can also affect fuel consumption to some extent.
