The wholesale cost of petrol delivered to forecourts has fallen for eight consecutive weeks by a whopping 20p from 151.93p at the start of June to 131.75p a litre in the last week of July.
The last time unleaded was this price on the wholesale market was in early May which a week later led to a UK average pump price of just 167p a litre.
Simon Williams, RAC’s fuel spokesperson, said July had been an “unnecessarily tough month for drivers” with major retailers not cutting costs.
He added: “As it was, we saw independent retailers leading the charge with fairer pump prices appearing all around the country which eventually forced the supermarkets to finally implement a more substantial cut late last Friday afternoon (July 29).
