How to repair the high fuel consumption of the new Alto after washing the throttle?

If it is a new car, the high fuel consumption has little to do with the car itself, but only the oil and driving habits. It is normal that the fuel consumption is high after the throttle is washed, the carbon deposit on the throttle is cleaned, the air intake is timely, and the fuel is fully mixed. If the mileage has exceeded 40,000 kilometers, it is recommended that you clean the fuel injector and fuel tank. The fuel tank can be cleaned by adding fuel additives.
