The big supermarkets cut their petrol prices for the second time in less than a week – but the AA said there was still scope for further reductions.
Tesco, Asda and Sainsbury are slicing 2p off a litre of petrol as wholesale prices continue to fall amid lower crude oil values.
The latest Asda cut will mean its customers will pay no more than 131.7p a litre of petrol from Saturdaymorning, with Asda diesel staying at 135.7p a litre.
But the price of petrol can still depend on location. This week, a substantial number of supermarket and non-supermarket fuel stations were selling petrol at 132p-133p a litre in Staffordshire, London and some other areas, according to the AA.
Edmund King, the president of the AA, repeated his call for the government to intervene and force oil companies to publish the price of wholesale petrol and diesel to help make pump prices more transparent.
"We are not calling for regulation but experience in the US, Australia and elsewhere shows that a bit more openness brings more stability. It might help remove the concerns of motorists that retail prices are quick to go up [when the wholesale price goes up] but slow to go down [when the opposite happens]".
Peter Cattell, Tesco's petrol category director, said both petrol and diesel could be reduced in price. "As Britain's biggest fuel retailer, with 497 forecourts, more motorists make savings at Tesco petrol filling stations than any other fuel retailer," he added.
Richard Crampton, Sainsbury's head of fuel, said: "We're always looking for ways to help customers save money and we know that fuel is a big part of household budgets, so from tomorrow we will be reducing the price of unleaded at our 280 forecourts by up to 2p per litre."
