Does the car air conditioner consume the same amount of fuel in first gear and fourth gear?

[Rosalie]

There is basically little difference in fuel consumption between the first gear, fourth gear, or other gears of the car air conditioner, and it can be negligible. Here are some tips for using the car air conditioner: 1. Ventilate before turning it on: After the car has been exposed to the sun for a long time, you should first open the four doors and the sunroof to allow the air inside the car to circulate for 3 minutes. This can quickly reduce the temperature inside the car, and the cooling effect of the air conditioner will be better at this time. 2. Use the internal circulation reasonably: The internal circulation blocks the hot air outside, creating a sealed space inside the car, allowing the air inside to circulate quickly under the action of the air conditioner to achieve rapid cooling. After the temperature inside the car has dropped, it is recommended to turn on the external circulation every 30 minutes to purify the air inside the car, and then switch back to the internal circulation after 5 minutes. 3. Turn off the air conditioner in time: Turn off the air conditioner 5 minutes before parking, which not only protects the engine but also saves fuel.
