Frequently Asked Questions
It depends on your car's MPG and the current fuel price. At 40 MPG and 135p per litre, £20 will take you approximately 52 miles. A more efficient car doing 55 MPG would cover around 72 miles on the same £20.
Motorway service stations have higher operating costs, a captive audience and less local competition, so they typically charge 10–20p per litre more than supermarkets or town centre stations. Our fuel station finder shows the premium in real time.
Yes. Aerodynamic drag increases with the square of speed, so driving at 80 mph uses significantly more fuel per mile than 60 mph. For maximum range from a fixed budget, steady motorway driving at 60–65 mph is typically most efficient.
