Motorists have been dealt a winter boost as petrol prices in the UK have fallen by the biggest margin for nearly five years, the AA said.
According to the motoring group, the average price of petrol fell by 5.49p a litre between the middle of September and the middle of October - taking the average price of petrol to 132.16p a litre.
This is the biggest monthly fall since November 2008, when prices fell by 11.5p a litre.
While the average petrol price is now 132.16p a litre, diesel stands at 139.2p a litre, following a fall during the last month of just 3.3p a litre.
The AA said the fall in prices would save an average of £2.72 when refueling a small petrol car at the pump, but households with a saloon car would save an average of £3.84 on the cost of refueling their vehicle.
The AA said two-car families could save as much as £10 a month on fuel.
Northern Ireland is the most expensive region for petrol at present, with fuel costing 132.9p a litre, while the cheapest areas are London, the North, and Yorkshire and Humberside where petrol is 131.9p a litre, according to the AA.
Edmund King, president of the AA, said: "A more than £2.50-a-tank cut in petrol costs for families is a dramatic improvement on its own. But heading into winter, with cars using more fuel, the timing couldn't be better."
The AA said the fall in prices is down to a decrease in the wholesale price of fuel, boosted by supermarkets such as Asda and Sainsbury's passing on the reduction to motorists.
