How long should you drive on the highway to reduce fuel consumption?

[Barnes]

The break-in period for a new car is generally 3,000-5,000 kilometers. After 3,000 kilometers, driving at high speeds can help remove engine carbon deposits to some extent. After the break-in period, fuel consumption will decrease. Methods to reduce fuel consumption: Change bad driving habits, avoid using low-quality gasoline, clean engine carbon deposits, avoid sudden acceleration, and clean the throttle valve. Cleaning the throttle valve: The throttle valve is a controllable valve that regulates air intake into the engine. After entering the intake pipe, the air mixes with gasoline to form a combustible mixture, which then burns to generate power. If the throttle valve has carbon deposits, it can lead to incomplete fuel combustion, insufficient power, and increased fuel consumption.
