MOST people know that the price of fuel on the autoroutes of France is more expensive, but a report claims the difference can be as much as 12.5 cents a litre for diesel.
Consumer watchdog, CLCV, said it also found a wide difference in prices in areas where autoroutes were not as busy, saying the lack of competition enabled petrol companies to push the price per litre up.
CLCV advised drivers to avoid filling up on autoroutes in the Meuse, the Marne, the Loire, the Corrèze or the Franche-Comté.
The association said it studied prices between February and June this year, with the average price of diesel on the autoroutes being €1.43/l against a price of €1.31/l on the rest of the French road network.
CLCV is calling on the government to boost competition on those autoroutes which have a small number of stations, and that the online database of prices has to be improved as it only has a few details for SP95 petrol prices.
