I’ve just been to a station (listed on mylpg.eu) near Laredo. The attendant said there’s a rule in all of Spain that one cannot fill gas bottles - and pointed to the graphic on the pump. I explained and showed him my external filling point - he still said no. However, he helpfully sent me to an ‘independent’ Repsol station about 15 Km away - who had no problem helping me fill. How have other Funsters fared in Spain?
