Ready to compare official Fuel Finder prices with Phil’s observed 219p/litre diesel price. Start the replay to calculate road detours.

WORTH THE DETOUR?

Fuel stops ahead

£

An accountant’s kind of road trip.

Use the Wetherby replay to find fuel stops ahead, or let your location and movement identify your road and direction.

50 litres at 219p costs £109.50. Let’s see what a short diversion could save.

How the comparison works

The app follows a road continuation ahead from your position and direction. It searches Fuel Finder forecourts within 5 km of that corridor, then requests a driving route to each forecourt and back onto the same road ahead.

Extra miles and minutes are measured against driving directly to the same rejoining point. Net saving = pump-price saving on your fill − extra fuel cost − optional value of extra driving time. UK mpg uses an imperial gallon (4.54609 litres).

Routes requiring a U-turn, an uncertain forecourt entrance, or an unconfirmed return to the road are excluded. The current road is inferred from routed geometry, not from a compass label alone. Fork choices cannot be predicted: the confirmed search distance is shown with each result.
