A little known and arguably under-used button in your car could help reduce your fuel bill. And with the costs of petrol and diesel continuing to rise, using this trick could come in handy and possibly save you some money this summer.
This driving hack works particularly well at reducing fuel consumption during short journeys and what's more, it'll also help keep you and any of your passengers comfortable.
The button is connected to your vehicle's air-conditioning system which uses engine power in diesel and petrol cars, and battery power in electric vehicles. And when that system is engaged in vehicles powered by internal combustion engines, it can lead to a huge amount of additional fuel being consumed, according to the Daily Express.
