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

[Carvalho]

Generally, fuel consumption during the break-in period is relatively higher, about 1-2 units more than under normal conditions. Here is the relevant information: Specific reasons: Mainly because the various components of a new car have not yet reached their optimal working state, and they are not smooth enough, resulting in greater frictional resistance, making driving more strenuous and thus relatively more fuel-consuming. However, after the break-in period, fuel consumption will decrease. Precautions: During the break-in period of a new car, try to maintain a steady speed and avoid overloading. For manual transmission models, it is necessary to shift gears promptly and appropriately, avoiding high gears at low speeds and low gears at high speeds. Also, do not drive in the same gear for extended periods, as this allows for more thorough break-in of the engine and transmission. As for the selection and replacement of engine oil, it is recommended to refer to the car manual.
