Motorists who fill up their cars with supermarket petrol will be in for a treat today.
Asda, Sainsbury's and Tesco are all slashing their petrol prices by up to 2p a litre from today.
Drivers who pop into an Asda filling station will pay no more than 133.7p a litre for their petrol. Asda diesel remains at 139.7p a litre.
The supermarket giant's petrol trading head, Jeremy Walton, said yesterday: "We always aim to be the first retailer in each part of the country to drop prices when costs are falling and the last to put them up."
Sainsbury's quickly followed suit after the Asda announcement.
The firm's head of fuel, Richard Crampton, added: "We're always looking for ways to help our customers save money, particularly as we head towards the festive season, so we're delighted that we will be reducing our petrol price by up to 2p per litre."
And a Tesco spokesman said: "We are dropping the price of unleaded fuel by up to 2p per litre from tomorrow morning.
"As Britain's biggest petrol retailer with 490 forecourts, more motorists will make savings at the pumps at Tesco than at any other fuel retailer."
Motoring organisation the AA welcomed the news, and pointed to its fuel-price report published last week. In it the AA found that a 4p drop in petrol wholesale prices is working its way through the system.
AA public affairs head Paul Watters said: "UK average petrol pump prices reached a late summer high of around 140p a litre in mid September and sat there for more than a fortnight. More than a month on, the average petrol price yesterday was down to only 138.70p a litre."
However, Watters warned: "Unless the rest of the market reflects the lower cost, it's a case of the same old story - prices up like a rocket, falling like a feather."
