Ways to cut your per-litre cost
Beyond picking the cheapest pump, three approaches change what you actually pay.
Fuel cards
Regular long-distance and cross-border drivers
Settle at a negotiated network price rather than the pump price, and reclaim VAT on foreign fills in one statement.
Watch out: Network coverage varies by country, and some cards carry a monthly or per-transaction fee that outweighs the discount at low mileage.
Supermarket and unmanned stations
Local driving with a station choice within a few kilometres
Unmanned and hypermarket forecourts consistently price below motorway and branded sites in the same area.
Watch out: A detour costs fuel too — the /detour calculator shows when the trip is worth it.
Part-electric running
Predictable commutes with home or workplace charging
Cost per 100 km on home electricity is typically well below diesel or petrol at current European pump prices.
Watch out: Public rapid charging can cost as much as fuel; the saving depends on where you charge, not on the car alone.
