All drivers in the UK are being urged to press a common button we all have in our cars before starting a drive. Experts say it could save you hundreds every year, and reduce your fuel consumption by as much as 10%.
It could save motorists even more money while the weather is hot. A heat wave has been predicted this weekend.
It will come as no surprise to motorists that an air-conditioning system uses engine power in diesel and petrol cars, and battery power in electric vehicles. For internal combustion engines that can lead to a much bigger fuel consumption.
The system usually works by taking the outside air and then heating or cooling it. However, drivers have now been told that this method uses much more fuel compared to the option which lets the car’s air-con system use the air from inside the car.
Thankfully, there is a button specially designed to let motorists choose which option they prefer. If activated, the air recirculation button, allows the aircon to use the air from inside the car by drawing it through vents.
And, at the same time, it stops the outside air from getting in. The button is usually located around the aircon dial that allows the driver to set the internal temperature.
It has a picture of a car with an arrow inside it. Using the button will help reduce fuel consumption as it puts less strain on the car’s engine says the Express.
The principle is the same for electric cars as the aircon will put less strain on the battery. Bradley Jando of Kwik Fit said: "The compressor requires energy to run your vehicle’s air conditioning system and so will use a small amount of fuel whenever the system is running.
