Frequently asked questions
Why convert gallons to litres?
UK fuel economy is quoted in miles per imperial gallon, but fuel is sold by the litre. There are about 4.546 litres in an imperial gallon, so the tool converts to price the journey correctly.
What mpg should I use?
Use your car's real-world average if you know it, as official figures are often optimistic. Motorway driving is usually more efficient than short urban trips.
