A rational approach to comparing service stations in France. Evaluate pump savings while factoring in distance, tank capacity, and actual detour costs.
The ACUMVIO fuel price comparator does not merely rank pump rates: it incorporates travel distance, fuel volume, and detour cost to compute the effective cost of your fill-up, eliminating misleading 'deals' that cost more in travel than they save.
How to mathematically determine if a station detour is worthwhile.
Volume added (L) × Price gap per liter (€/L). Example: 50 L × €0.06/L = €3.00 gross savings.
Round-trip detour (km) × Average consumption (L/100 km) × Fuel price. Example: 8 km at 6 L/100 km = 0.48 L consumed (~€0.80).
Gross savings - Driving cost - Vehicle wear. If positive, the detour is profitable; otherwise, stay on your route.
Pick the right tool for your specific travel scenario.
Instantly compare declared rates within a selected radius around your position.
Compare stations directly on your highway corridor with minimal stop time.
Compare weekly trends to decide whether to refuel today or tomorrow.
Compare the real cost per kilometer of your car vs official allowances.
The most common mistake is driving to the cheapest station on the map without considering distance. If that station requires a 7 km detour, the 14 km round-trip in traffic consumes fuel and adds vehicle wear.
Factoring in urban driving consumption, a detour can cost €2.50. If you only need 30 L with a 4-cent saving (€1.20 saved), you actually lose over €1.30 overall.
Always compare like-for-like: SP95-E10 against SP95-E10, or standard diesel against standard diesel.
For Superethanol E85, compare cost-per-kilometer rather than price-per-liter to account for the 20–25% higher consumption of ethanol.
ACUMVIO aggregates official price registries in France and pairs them with your GPS position or route. It calculates net savings by deducting detour driving expenses.
