Motorists should not start the celebrations just yet. The average pump price for unleaded petrol is still around £1.07.
Today I spoke to industry insiders from supermarkets and independent fuel retailers.
They are not as bullish as the RAC in believing prices will get so low. They say that to reach £1 a litre on average will require more sustained drops in wholesale prices.
Even then, there can be a two-week time lag before effects reach the forecourts. Many supermarket prices are short-term promotions to lure in the festive shoppers. So it might be top of their wish list, but drivers may not get what they want for Christmas.
