Little-known button inside your car that can save money on fuel

Motorists across the country have been advised to take advantage of a little-known button inside their vehicles to save money on fuel. This simple action not only helps to make the journey more comfortable, particularly in the recent heatwave, but also contributes to reducing fuel consumption.

It's no secret that the air-conditioning system in cars relies on engine power in petrol and diesel vehicles, or battery power in electric cars. However, what many drivers may not be aware of is the significant impact this has on fuel consumption in internal combustion engines.

Typically, the system works by drawing in outside air and then either cooling or heating it. However, experts have recently revealed that this method consumes a substantial amount of fuel compared to an alternative option that utilises the air from inside the vehicle. Thankfully, there is a specially designed button that allows motorists to choose their preferred option. By activating the air recirculation button, the air-con system draws air from inside the car through vents while preventing outside air from entering.

This handy button is usually located near the air-con dial, which allows the driver to set the internal temperature. It features a clear image of a car with an arrow inside. By using this button, motorists can significantly reduce fuel consumption as it eases the strain on the car's engine. The same principle applies to electric cars, as the air conditioning system exerts less pressure on the battery.

Bradley Jando, from 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.

"It could increase your fuel usage by as much as 10 percent,
