Does idling the car with the air conditioning on consume fuel?

[MatthewLee]

Fuel consumption when idling the car with the air conditioning on: Under normal circumstances, if a car consumes 10L of fuel, turning on the air conditioning will increase fuel consumption by approximately 2L. Fuel consumption is significantly affected by whether the air conditioning is on or not, and the impact varies with different fan speeds. Here are some methods to reduce fuel consumption: 1. Check the air conditioning system in summer: Air conditioning malfunctions are a major cause of high fuel consumption. If the cooling effect is poor, it will require higher fan speeds and lower temperatures to achieve a cooling effect. 2. Frequent hard braking: Frequent hard braking is a primary reason for persistently high car fuel consumption. While ensuring safe driving, make full use of the vehicle's inertia. 3. Avoid setting the air conditioning too high in small-displacement cars: For vehicles exposed to the sun, it is not advisable to turn on the air conditioning immediately after getting in. First, open the windows and set the fan to a higher speed without turning on the air conditioning to expel the hot air inside the car. Wait until the car has cooled down moderately before turning on the air conditioning.
