How much fuel does a large vehicle consume when idling with AC on for one hour?

[JuniperFitz]

When a car is idling with the air conditioning on for one hour, it typically consumes around 2 liters of fuel. Below 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 air conditioning, but if you smoke with the AC on, the smoke cannot be promptly vented outside the car, which can harm the eyes and respiratory system. 2. Avoid adjusting the temperature randomly: To quickly cool down the car, many people set the AC temperature to the lowest level. While this may feel comfortable, it can directly affect the body's endocrine system. If the temperature remains too low for a long time, it may lead to symptoms like leg soreness and overall chills. It's best to keep the temperature difference between the car and the outside within 5-6°C.
