How Much Does Using Car Air Conditioning Increase Fuel Consumption?

[McBenjamin]

The specific increase in fuel consumption when using car air conditioning depends on the vehicle model and the size of the air conditioning system, and there is no exact figure. Minimize the use of air conditioning: Especially during traffic jams or when parked, avoid keeping the air conditioning on continuously when the car is stationary. Turn off the air conditioning completely when not in use: When air conditioning is not needed, it should be completely turned off. This not only reduces energy consumption but also minimizes wear and tear on the air conditioning system. Set the air conditioning to the highest level upon vehicle startup: After starting the vehicle, you can set the air conditioning to the highest level. Once you feel it has achieved sufficient cooling effect, turn it off. This allows the air conditioning to skip the step of mixing with warm air, achieving maximum cooling efficiency while also saving fuel to some extent.
