after a long time back

i wonder myself looking at the stations list and comparing it to the offical site of the ministry of economy, industry and work http://www.prix-carburants.gouv.fr/inde ... tE85Prices
they have listed over 600 stations, and here only nearly the half amount is listed. so i ask myself, which list may be the corrcet oder better one?
could you help me, please?
thank you.
