Major UK supermarkets have announced a round of petrol price cuts from Tuesday.
Asda kicked off the cuts with a reduction of up to 2 pence a litre, followed by other supermarkets including Sainsbury's and Morrisons.
Falls in wholesale prices and a more favourable exchange rate are behind the cuts, the AA motoring group said.
Supermarkets reduced pump prices in March, and last week cut about 2 pence a litre off diesel.
AA president Edmund King said: "We predicted these cuts last week, with oil down to its lowest level in a month and the pound gaining on the dollar after its recent fall.
"This is perhaps another glimmer of sunlight for drivers after a hard, wet, pot-holed and expensive winter of driving."
A rise in fuel duty scheduled for September was cancelled by Chancellor George Osborne in his Budget last month.
