Get the Trier/Wasserbillig (line 30) train from Luxembourg City station for EUR 2.00. Get off at the Wasserbillig stop. You should turn 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 there 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.

Get the line 60 train from Luxembourg City station for EUR 2.00, or avoid the controller for 2 stops. Get off at the Berchem stop. There are 2 exits from the station. Take the closest one, don't take the stairs. And walk less than 2 km to some of the biggest motorway petrol stations in Europe! Take the first little path to the residential area (Rue Oscar Romero), pass a tiny roundabout and walk up towards the fields. Then you have a beautiful path through the fields straight ahead. You'll pass by generous walnut and apple trees, you'll have to climb over small cattle fences, and might say hi to some animals. Otherwise: Turn left when you leave the Berchem train station, walk down the road 5 minutes and the second main road on the right is Rue Meckenheck. Take Meckenheck up winding through a residential area all the way up to where it ends, at which point there is a big forest. Turn right onto Du Bois, and follow it curving around to the left. You should hear the highway and pretty soon you will arrive at a bridge[https://www.google.ca/maps/place/49%C2%B032'40.2%22N+6%C2%B007'18.3%22E/@49.544506,6.119553,17z/data=!3m1!4b1!4m5!3m4!1s0x0:0x0!8m2!3d49.544506!4d6.121747?hl=en] that runs over the highway. Just before the bridge is the south-side petrol station, with loads of cars heading north towards Luxembourg city, Belgium, Netherlands and Germany.

Take bus number 18 (from Central station to direction Kockelscheuer, Patinoire). Tickets costs 2 euro - 1 way or 4 euro - one day ticket (valid till 4am and its for bus, trams and local trains!) Get off from bus on the bus stop "Plantin" (few meters before this bus stop is Shell petrol station). Go straight to rond-about and then turn left. Few meters from rond-about there will be place where you can easily hitch-hikke (bus stop, rarely use). On the opposite side of this place there is Auchan Drive so it's easily to find.
