Which is More Fuel-Efficient: Recirculating or Fresh Air Mode in Car AC?

[DiMiranda]

Using the recirculating mode is more fuel-efficient than the fresh air mode. However, the actual difference in fuel consumption is minimal, with the fresh air mode consuming approximately 0.1 liters more per 100 kilometers compared to the recirculating mode. Below is an introduction to the factors affecting fuel consumption and methods to reduce it: Factors Affecting Fuel Consumption: There are numerous factors that influence fuel consumption, including driving conditions, driving habits, engine displacement, vehicle load, etc. However, under normal driving conditions, fuel consumption typically falls within a certain range. Methods to Reduce Fuel Consumption: Shift gears promptly: Prolonged driving in low gears not only results in slower speeds but also increases fuel consumption. Shifting gears quickly, especially when driving on slopes, can help save fuel. Minimize idling time: When driving in urban areas, you may encounter long waits at traffic lights. Turning off the engine during these times can help reduce fuel consumption. Drive at an economical speed: For most passenger cars, the economical speed range is between 60 km/h and 90 km/h. Driving within this range ensures the lowest fuel consumption.
