Motorists are enjoying the biggest fall in petrol prices since the credit crunch days of 2008.
But the AA has warned that a further dip in prices is unlikely.
Average petrol prices in the UK fell 5.49p a litre between mid September and mid-October – the biggest monthly fall since the 11.5p petrol price collapse in November 2008, the AA said.
Petrol is now averaging 132.16p a litre, while diesel has dipped from 142.50p a litre to 139.12p.
The AA said the price falls have cut £2.74 off the cost of refuelling a small petrol car and £3.84 off the bill for a Ford Mondeo-sized petrol vehicle. A family with two petrol cars will have seen the monthly fuel bill fall by £10.
