Supermarkets need to do more to cut petrol and diesel prices in order to match a drop in wholesale fuel. The RAC have slammed the retailers who aren't matching the "significant" decrease in wholesale fuel costs.
Several supermarkets, including the four major fuel sellers, Tesco, Sainsbury's, Asda and Morrisons are currently being undercut by a number of independent retailers that are passing on the wholesale cost savings to customers.
The RAC have said this change in behaviour is usually unheard of. Supermarkets have often been known to be the cheapest place to buy petrol and diesel because they buy fuel more frequently, meaning they can react quickly when wholesale prices move up or down.
