Cheap fuel: the route decides the price, not just the pump

The cheapest gas station nearby is not automatically the best choice. A ten kilometre detour burns fuel and time, and quickly eats up the saving per litre. Tankmapper adds everything up: price per litre, the number of litres you actually need and the cost of the detour on your own route.

Three steps to the cheapest fill-up

1. Enter your start and destination — the route appears on the map straight away.
2. Set your tank level with the fuel gauge, in litres or as remaining range. You can also pick your make and model to fill in tank size and consumption.
3. Choose your maximum detour — Tankmapper picks the station with the lowest total cost.

What really drives your fuel bill

• Motorway or local roads: motorway stations are almost always dearer than a pump a few minutes away.
• How much you fill up: two cents difference is small on 10 litres and significant on 55 litres.
• The detour: every extra kilometre costs fuel, and that cost is deducted before any station is recommended.
• Border regions: near Belgium, Germany, Luxembourg or France a cross-border comparison often pays off. Compare countries.

Where the prices come from

Tankmapper uses per-station pump prices from the public station feed, OSRM routing and open vehicle data. When you plan, you see when the prices were fetched — reported prices per station, not estimates.
