How much fuel does a car consume when idling with the AC on for an hour?

[Alana]

When a car is idling with the AC on for about an hour, it typically consumes around 2 liters of fuel. Here is some relevant information: 1. Do not smoke while the AC is on: Many people occasionally smoke to stay alert while using the car's AC, but smoking with the AC on prevents the smoke from being promptly vented outside the car, which can harm the eyes and respiratory system. 2. Avoid adjusting the temperature arbitrarily: To achieve quick cooling, some people set the car's AC to the lowest temperature. While this may feel comfortable, it can directly affect the body's endocrine system. Prolonged exposure to excessively low temperatures can lead to symptoms such as soreness in the lower limbs and overall chills. It is best to maintain a temperature difference of 5-6°C from the outside environment.
