Almost every car has a little button that isn't widely known about but can help to improve fuel consumption.
Drivers can save money literally at the press of a button with a useful fuel and money saving 'hack'. The tip has been popularised by TikTok star "Megan's Bubble" and also has the backing of an AA spokesperson.
Taking to the video sharing platform, the user captioned her clip: "Car tips and tricks. I bet you didn't know what this car button is actually used for."
