if you mean the shell at J2 on the A38 yes you can get it there you can also get it a the shell garage on the way from koblenx/waldshut to rheinfelden quiet a big car park to stop
if you put that route in a toll collect machine it’ll tell you it’s free aswell cant remember what exactly it does but it’s impossible to get a card for it
thats from the border by mulhouse to wiel not 100% sure bout lorrach
