Cheapest can change once the detour is counted
A lower station price is not always the better stop. The app can factor in how far each stop is from your journey, distance and fuel used getting there.
How Route & Fuel ranks a stop
The lowest station price is only the starting point.
1Gross price saving
Compare the station price with the expensive option on your route or nearby list, then multiply the pence-per-litre gap by the planned fill amount.
2Detour fuel used
Estimate the fuel needed to reach the station using your MPG and the extra distance. In the app, route checks can replace rough distance guesses.
3Saving after extra driving
Subtract detour fuel cost from the station price saving. Live traffic time is shown clearly so a slow diversion does not hide behind a low price.
Full route saving check in the app
Check the saving before you fill, then save the result.
The website previews nearby and route prices using estimated extra driving. The app checks the full drive, live traffic and uses your vehicle, litres and wider search radius, then lets you save the fill-up so your savings history builds over time.

See detour time with live traffic
Live traffic checks can improve ETA and detour estimates for top route stops first, so a low station price does not hide a slow diversion.
Open the stop as a route
Pick a station and open directions in Google Maps so the fuel decision becomes easy to act on.
Estimated MPG and tank level matter
Your car and remaining fuel range change the useful saving, especially on longer journeys where a small detour can wipe out the headline price saving.
Fuel along the way
Fuel stops are part of the journey, not a separate search.
A postcode fuel finder can show nearby prices. Route & Fuel helps answer the better question: which fuel stop makes sense for the journey you are already taking?
Plan the saving logic here, then use the app for precise nearby results, station directions, favourites and fill-up tracking.
Personal route decisions
Why the app gives the better stop decision
The website gives a quick route preview: prices, route examples and a free planner. The app goes further with saving checks, calculated savings, station map, saved vehicles, route checks with live traffic, favourites, price alerts, fill-up history, fill-up rewards, synced preferences, dark mode and faster Google Maps handoff.
That helps Route & Fuel show station price saving, extra fuel cost, detour timing and the saving calculated after extra driving in pounds, based on the route and vehicle details you provide.
Prices in your pocket
A mobile app is a real advantage when signal drops.
Route & Fuel is built as a phone and tablet app, so already downloaded fuel prices and station data remain on your device on the go when mobile signal is patchy. Live route calculations and live traffic still need a connection, but your last saved price information, favourites and recent fuel details are not lost.

Route planner FAQs
Questions drivers ask
How can I find petrol stations on my route?
Enter your start and destination to see petrol stations on your route. Compare each stop's pump price with the extra miles and fuel used; the app also uses your car's MPG, fuel remaining and live traffic before you choose.
Is the cheapest fuel always worth the detour?
Not always. A cheaper station price can be cancelled out by detour distance, fuel remaining, traffic and fuel used getting to the station.
Does Route & Fuel work for petrol and diesel?
Yes. It supports common UK fuel types including E10 petrol, B7 diesel, E5 super unleaded and premium diesel.
