Peugeot 4008 also travels at a high speed of 420km. Why do you consume 40km more fuel when you come back? Ask professionals for help. Thank you.

Hello, I don't know whether this routine maintenance is related to carbon deposit cleaning or throttle cleaning. If not, your situation is mainly the fuel consumption determined by the driving habits of the vehicle during driving, and the overall weight and inertia force of the vehicle under heavy load and high speed are relatively large. Relatively speaking, high speed and uniform speed are more fuel efficient than empty cars! If you clean the throttle, this computer will have an adaptation process just after cleaning, so the fuel consumption will be high!
