Fuel Saving Tips
Use “Recirculate” setting for A/C in hot weather
In hot weather, your car’s air conditioner works less hard (and saves fuel) if you recirculate the already cooled cabin air, rather than continuously cooling hot outside air before it enters your cabin. Less A/C compressor load equals less fuel consumed. Additionally, this might save fuel by needing/using a lower cabin fan speed. Your car’s engine drives the alternator, which recharges the battery and feeds the car’s electrical load. A lower electrical load equals less fuel consumption.
