See the petrol cost from A to B

The Roadtrip app easily shows the cost to drive from A to B in your exact car model. It's super easy to use – just type in your car number plate – plus it's completely free to see petrol prices, with no ads. What's really clever is that it shows the cheapest petrol stations along a route, and it has a "Cheaper Nearby" function which highlights if there's a cheaper station close by.

Fuel prices can vary dramatically across different parts of the UK, and your vehicle's fuel efficiency plays a big role in the total cost of your trip.
