Fuel and Route Economics

Estimated fuel cost for a 7L/100km car: €88 (based on €1.40/L average). Efficiency tip: maintain 110 km/h on French highways to save fuel due to rolling hills. Use cash or credit card; Luxembourg often has cheaper fuel (€0.20/L less).

• Fuel station distribution: frequent in Germany/Luxembourg, sparse in Jura mountains (fill up in Lons-le-Saunier).
• Toll fees: A31/A36/A48: ~€45; A4 (alternative) €38.

The route passes the Moselle valley vineyards, Luxembourg's forested plateaus, the Lorraine plains, and the Jura limestone ranges. UNESCO sites: the Roman remains in Trier (deviate 30 km east) and the Vizille castle near Grenoble. No direct UNESCO on route, but both are short detours.
