How Much Does Fuel Consumption Increase When Using Air Conditioning in Summer?

[StKatherine]

Using air conditioning in summer generally increases fuel consumption by about 10%, with a maximum increase of no more than 20%. After the car has been exposed to the sun for a long time, you should first open all four doors and the sunroof to allow air to circulate inside the car for 3 minutes. This will quickly lower the interior temperature, making the air conditioning more effective when turned on. Proper use of the car air conditioning's recirculation mode: The recirculation mode blocks the hot air outside, creating a sealed space inside the car. This allows the interior air to circulate quickly under the effect of the air conditioning, achieving rapid cooling. Once the interior temperature has dropped, it is recommended to switch to fresh air mode every 30 minutes to purify the air inside the car. After 5 minutes, switch back to recirculation mode. Reason for turning off the air conditioning in advance: Turn off the air conditioning 5 minutes before parking. This protects the engine and saves fuel.
