Does a car consume more fuel when idling with the AC on?

[VanLaila]

Yes, a car consumes more fuel when idling with the AC on. Here are some ways to reduce fuel consumption: 1. Close the windows: Driving with windows open increases wind resistance, which in turn increases the resistance the car faces, requiring more power and thus increasing fuel consumption. 2. Regular vehicle maintenance or checks: Timely oil changes can reduce carbon buildup (carbon buildup can cause uneven ignition, sluggish acceleration, increased fuel consumption, and in severe cases, even cylinder misfires). 3. Replace fluids on time: If the engine oil is not replaced promptly, the car's shaking will become more noticeable, and fuel consumption will also increase.
