How much more fuel does using AC consume?

[Shaun]

Generally, it consumes an additional 1-1.5 liters per 100 kilometers. For vehicles with larger displacements or more spacious interiors, the consumption is slightly higher, approximately 15-20% more than when not using AC. The following outlines the hazards of idling with AC on: Higher fuel consumption: Idling with AC on consumes more fuel, typically around 2L/h. Therefore, prolonged idling with AC on can burn a significant amount of fuel. If the vehicle is low on fuel, it may run until it stalls. Engine carbon buildup: Due to incomplete fuel combustion during idling, engine carbon buildup can occur. Severe carbon buildup can affect the vehicle's normal startup, reduce engine power, increase fuel consumption, and lead to excessive exhaust emissions.
