Check stations that make sense for the road you are already taking, not just stations that are cheap somewhere nearby.
On this route, a cheaper station price only matters if the turn-off is still worth it. Route & Fuel helps compare real station prices, detour fuel, how far each stop is from your journey, fuel range and traffic before you choose a stop.
London to Birmingham gives drivers a choice between motorway convenience and off-route price checks. The app can compare the stop against the journey instead of only the sign at the station.
Check stations that make sense for the road you are already taking, not just stations that are cheap somewhere nearby.
A lower station price only helps if the extra miles, slower roads and fuel used still leave a real saving.
Traffic can change the best stop, especially on busy motorway and commuter routes.
Tank level, planning MPG and fuel type change which stations are useful on a longer journey.
Motorway services on the M1, M40, M42 and M6 can be convenient, but off-motorway stations near junctions can look cheaper until the turn-off is counted.

On a London to Birmingham trip, a 6p per litre saving on a 45 litre fill is worth £2.70 before the detour. If choosing between the M1 and M40/M42 adds about £0.85 of fuel around Milton Keynes, Northampton or Coventry, the useful saving is closer to £1.85.
The point is not to chase every cheaper station price. The point is to spot the stops where the price difference is big enough to survive the detour.
Use the page to plan the idea, then use the app to compare live station options, fuel filters, how far each stop is from your journey, fuel range and traffic before choosing a stop.
Once you pick a station, Route & Fuel can hand the stop to Google Maps for directions.
Plan common or unfamiliar journeys before you set off. The app can compare price, detour, fuel range, fuel type and traffic before treating a station as the smarter choice.
Only if the station price saving is bigger than the cost of the turn-off. Route & Fuel helps compare the price difference with detour fuel and how far each stop is from your journey.
Yes. A station that looks best on price can become a poor choice when the diversion is slow or awkward.
Yes. E10, diesel, super unleaded and premium diesel can have different prices, and your fill size changes the real saving.
