Does Starting the Car or Idling Consume More Fuel?

[StSara]

Idling consumes more fuel than starting the car. The reasons are as follows: Starting the car without moving: It doesn't consume much fuel, but the fuel consumption rate is low, which is bad for the engine. Idling consumes fuel: Idle state refers to a working condition when the engine is running without load. The consequences of idling include: Shortening the engine's service life. Easily damaging the three-way catalytic converter. Increasing engine carbon deposits. Excessive carbon deposits and dirt in the throttle and surrounding intake passages can change the cross-sectional area of the air passage, making it impossible for the control unit to precisely control the idle air intake, resulting in an overly rich or lean mixture and abnormal combustion.
