Fill up before Germany: save 5–12 c/L
Both France and Germany publish live station-level prices — France via prix-carburants.gouv.fr, Germany via MTS-K. On most crossings, French E10 near the border corridor runs 5–12 c/L cheaper than German motorway stations. The gap narrows or reverses at German city stations off the motorway.
Decision question
Should the driver fill before the border or compare German stations after crossing?
What Kilomo should compare
- German MTS-K prices refresh multiple times daily for every registered station — the E10 price at stations near Kehl or Saarbrucken is verifiable before you make the turn.
- French open-data prices (prix-carburants.gouv.fr) update at each operator price change — live on both sides of the border simultaneously.
- French E10 along the A35 Alsace and A31 Lorraine corridors typically runs 5–12 c/L below German motorway service stations. The gap shrinks at well-priced German city stations off the motorway.
- Practical rule: if the last French exit before the crossing has a station within 2 km and the live gap is above 5 c/L for your fill size, stop — German prices after the border won't consistently beat it.
