My 1.4L Big Dipper consumes more than 9 kilometers' how to reduce fuel consumption?

1, clean the carbon deposit and fuel nozzle, and use 30 viscosity engine oil.

2, develop good driving habits, do not slam on the accelerator, do not slam on the brakes.

3. Drive at the right speed in the right gear. The shift speed is above 1800, around 2000. Don't shift gears until the speed increases. Do not use low speed or high speed.

4, parking more than 1 minute, it is best to turn off the fire.

In fact, in addition to the engine itself, it is mainly the driver's driving habits and road conditions.
