There could be some festive cheer at the pumps for motorists, with the cost of filling up the car set to drop below £1 a litre.
The RAC believes the falling price of crude oil will be felt at the pumps in the first few months of 2015 - at their lowest level since 2009.
The cost of Brent crude is continuing to drop after reaching its lowest point since May 2009 on Tuesday.
The average price of petrol is already nearly 14p a litre cheaper than at the start of the year and diesel is almost 16p a litre cheaper.
RAC fuel spokesman Simon Williams said: "Talk of prices going up like a rocket and falling like a feather could not be further from the truth as retailers have been quick to pass on savings at the forecourt.
"It's also important to remember that while the cost of fuel itself has fallen, it currently only represents around a third of the overall pump price with the lion share being made up of fuel duty and VAT.
"At £1 a litre duty would be 57.95p and VAT 16.67p, leaving the cost of the oil and retailers' margin at 25.38p – meaning tax would be three quarters of the forecourt price."
