Two months after supermarkets cut diesel prices below unleaded petrol Asda has been the first to restore petrol’s position as the cheaper fuel.

On Wednesday 23rd September Asda cut the price of unleaded by 2ppl, making its national price cap105.7ppl on unleaded while diesel remained at 107.7ppl.

Andy Peake, Asda’s senior director for petrol, said: "We’re now seeing unleaded move back to its traditional place after two months of diesel being the cheapest fuel grade."

Tesco, Morrisons and Sainsbury’s then said they were cutting up to 2ppl from their unleaded petrol.
