You can know exactly how much fuel you have left by noting how much it took to fill, and subtracting that from the fuel tank capacity.
For instance, my Prius is rated almost exactly 10 gallons (10.2). If I put 9 gallons in to fill it, I know I had 1 gallon left despite the gas light having come on 60 miles ago...
So, I make note of when the gas light turns on, and how much fuel I had left after filling to determine how far I can go "on the gas light". I probably always know within quarter gallon how much fuel I've got left.
Knowing with precision how much fuel remains can reduce your anxiety when all the gauges are telling you the car will stop at any moment.
Regarding cheap fuel, tell Mum to install the Gas Buddy app.
