How Much Fuel Does Idling with AC On Consume?

For typical family cars, idling with the air conditioning on for about one hour consumes approximately 1-2 liters of fuel, though this may vary depending on the vehicle model. Fuel-saving tips when using AC: 1. Ventilate before turning on AC: If the car has been parked outdoors in summer, it's best to open the windows before getting in and not immediately turn on the AC. Set the fan to maximum speed to accelerate ventilation and wait for the hot air inside to dissipate before activating the cooling function. 2. Direct air vents upward: Adjusting the AC vents to face upward improves cooling efficiency through physical airflow dynamics. 3. Avoid setting the temperature too low: Do not keep the AC at the lowest temperature setting for extended periods, as a significant temperature difference between the interior and exterior can increase fuel consumption and negatively affect the health of the driver and passengers.
