After car maintenance, there are problems of low power and increased fuel consumption.

After general maintenance, the biggest factor that can replace the increase of fuel consumption is that after washing the throttle, ECU adapts to the maximum fuel injection quantity with different throttle opening by default.

Reasons for high fuel consumption:

1, if the tire pressure is abnormal or the big tire is replaced, the tire inflation will affect the fuel consumption. When the tire pressure is too low, the contact area between the tire and the ground will increase, the driving resistance will be greater, and the vehicle will naturally waste more oil.

2. It is also a good fuel-saving method to clean the car irregularly and wax it regularly. The biggest resistance of vehicles in driving comes from air.

3. Don't turn off the fire or strike a light frequently when idling for a long time. When waiting for a long time without moving the vehicle, it is suggested that the owner can choose to turn off the engine.
