Tesco, Asda, Morrisons, Sainsbury's drivers who buy petrol or diesel handed £416

It means somebody filling up twice a week - the UK average - will save £416 a year.

Fuel prices are falling at record speed with road users, motorists and drivers able to fill up on petrol and diesel for £4 LESS than a month ago. It means somebody filling up twice a week at Tesco, Asda, Morrisons or Sainsbury's, the big four supermarket retailers - the UK average - will save £416 a year.

The latest data from the RAC showed a steep fall in rates as pressure mounts on the industry to pass on savings to motorists. According to the Club's Fuel Watch service, a litre of unleaded petrol now costs 136.15p on average, having dropped around 5p since the start of this month alone.

And compared to the same time last month the decrease is even sharper, sitting at 7p overall. Diesel has declined by 5p since then, dropping to just over 140p per litre, the figures - released this week, September 23 w/c, have revealed.

RAC fuel spokesperson Simon Williams suggested that prices could fall to their lowest since 2021 by the end of the month. This could see petrol go as low 132p per litre, with 138p for diesel, he commented earlier this week, in an update to drivers.

He said: "It's really encouraging to see pump prices coming down so rapidly, which we know is as good for drivers' wallets as it is for keeping the headline level of inflation in check. With the cost of filling up making up a sizeable chunk of many households' overall monthly spending, it makes sense to stretch every pound spent on fuel as far as possible.

"The message to drivers is simple – keep shopping around for fuel and use the available free tools out there, like the myRAC app, to always pay the lowest price wherever you can." Howard Cox, founder of FairFuel UK, said: "It's great that pump prices are at their most attractive this year.

"The bad news though, is that they should be 5p even lower as the greedy unchecked fuel supply chain ignores attractive wholesale prices, and continues to ignore PumpWatch by keeping petrol and especially diesel opportunistically high. Worse still, the Chancellor is set to increase fuel duty by as much as 10p per litre.

She will take advantage of these lower pump prices to fleece drivers ruthlessly."
