Asda has decreased the cost of petrol across 320 UK filling stations, but the move should have happened “much sooner”, RAC has said.
Despite Asda not announcing the price reductions, the Big 4 grocer has dropped by an average price of 4.5p per litre in the past two days.
Diesel prices have been cut by an average of 5.5p per litre.
“While we’re pleased one major supermarket retailer has finally started heeding our calls to pass on the enormous drop in the wholesale prices of both fuels, the fact these price cuts have been made so quietly is surely admission that they should have come much sooner,” RAC fuel spokesman Simon Williams said.

“Asda is now charging an average of 153.5p for petrol and 176.7p for diesel which is around 2p less than its rivals.”
He added: “We urge the other three supermarkets to catch up quickly – or go even further – and give drivers some much-needed relief from high prices next time they fill up.”
“If they do, this will bring the UK average petrol price down from its current 157.8p which benefits drivers everywhere.
The news comes as the RAC accused supermarkets of “hanging on to massive margins for dear life”, despite fuel prices falling 6p per litre in November.
