Asda and Sainsbury's have slashed petrol and diesel prices after four consecutive months of fuel price rises.
The retailers announced on Wednesday (June 5) they will drop the price by up to 3p per litre across all of their filling stations following a cut in the cost of wholesale oil.
Petrol previously became 11p a litre more expensive between the start of February and the end of May, reports North Wales Live.
Diesel was also up 7p a litre over the same period, RAC data reveals.
The RAC are now urging all retailers to follow suit as quickly as possible to reflect the sudden drop in costs.
Spokesperson Simon Williams said: “Diesel drivers especially will be relieved to see pump prices finally going down instead of up.
"It’s important to realise that the drop in wholesale costs has been dramatic meriting far bigger price reductions for both petrol and diesel. For this reason we view this round of cuts very much as a good start. We should really see more in the next week or so.
“We would very much like to see retailers reflect wholesale price reductions more closely.
"This is particularly the case with diesel which has been a similar price to petrol on the wholesale market for some time, yet is still 5p a litre more expensive on average on the forecourt.”
