On average, you probably have between 30-40 miles left the moment your petrol light comes on. Ideally, you should get to a filling station at your earliest convenience so as not to end up running on fumes. The bottom of your tank is lined with a yucky sediment, which can clog the fuel filter and fuel injectors, as well as the pump pickup if you don’t refuel when prompted.
Ideally you should aim to top up your fuel when the tank gets to a quarter full – this will actually save you money in the long run and keep your car running healthily. You wouldn’t go jogging on an empty stomach, would you? Taking efficient care of your vehicle will not only will you ensure your own safety and convenience, but lessen the impact on your wallet too!
Safe driving from Britannia!
