Get the Trier/Wasserbillig (line 30) train from Luxembourg City station for EUR 1.50. Get off at the Wasserbillig stop. You have two options (a local and a national one). The local one is if you should turn left, walk down the local road for two minutes, you should see around 7 petrol stations. Maybe somebody can bring you to the main Wasserbillig service station on the motorway or wherever else.  The national options involves turning right outside the train station, walking up the road and turning left up the Route d’Echternach until you reach a crossing beside a big river. This option takes 30 minutes but is more effective than the local onethere are beautiful views to be seen. You will notice that there is an old pathway going up the hill. If you follow this route you should arrive at two old cabins. Turn left at the cabin closest to you and walk further up the hill until you reach another crossing under the massive motorway bridge. Go right at this and keep climbing the hill until you reach a more developed road. Here, you turn right and keep following the access road until you reach the petrol station. This is located at the Luxembourg-German border. There should be plenty of international traffic.
