Europe fuel prices: the official data sources
France updates station-level prices at every operator price change. Luxembourg sets a regulated ceiling by decree every 1–2 weeks. Belgium and Germany publish official data on different refresh cycles. This guide explains what each source can and cannot guarantee, and when to trust the numbers.
Decision question
Which data is regulated, which is station-level, and where can it become stale?
What Kilomo should compare
- France (prix-carburants.gouv.fr): station-level prices updated at every operator price change — near-real-time open data covering virtually all French stations.
- Luxembourg: prix maxima set by ministerial decree every 1–2 weeks — a single regulated ceiling applied identically at every station, with no station-by-station variance.
- Belgium (FPS Economy): maximum retail prices updated weekly — a regulated reference ceiling; actual pump prices may sit below the maximum but not above it.
- Germany MTS-K (Bundeskartellamt): every registered station must report price changes within 5 minutes — multiple intraday updates, station-level accuracy, publicly accessible.
Quick answer
Kilomo combines public fuel-price sources with route logic. France and Germany provide station-level data in Kilomo, while Luxembourg and Belgium currently use national price data. This means some routes can show specific stations and others are better treated as country price comparisons. Kilomo is a route decision helper, not an official price publisher.
FAQ
Is the cheaper fuel stop always worth it?
No. It depends on how many litres you fill, how large the price gap is and how far the station is from your real route.
When is a fuel detour usually worth it?
A short detour often works when you fill 40–50 L and the price gap is around 8–12 c/L. Small top-ups or long detours are usually not worth it.
Does Kilomo guarantee the final pump price?
No. Kilomo uses public fuel-price sources and route logic to support the decision, but final pump prices and station availability can change.
