For the first time in nearly a decade-and-a-half, diesel is cheaper than unleaded petrol at some filling stations. The RAC has already applauded the move, declaring their hope that more retailers around the UK will follow suit and give motorists the chance to benefit from the decreased prices. Currently, the RAC believes there is scope for making further cuts of up to 40 per litre, with the wholesale cost of diesel currently well, well below wholesale petrol. Diesel prices are currently 118.98p per litre, with unleaded currently at 117.24p.æ Diesel costs have been lower than petrol since May this year. RAC fuel spokesman, Simon Williams, said: 'RAC Fuel Watch records show diesel was last cheaper than petrol 15 years ago on 17 July 2001, so these price cuts are great news for the nation's 10.7 million diesel car drivers. 'Fifteen years ago when this happened last diesel was cheaper than petrol for two-and-a-half months, but with a new supply of diesel being produced from Saudi Arabia there is real chance that we may see the diesel price staying below petrol for some considerable time. 'With the price of crude oil standing at $56.50 and the pound relatively strong against the US dollar _ the fuel trading currency _ there is scope for further price cuts of up to 4p per litre off diesel over the next fortnight, and unleaded may even benefit from a slight reduction too due to the continued oversupply of oil. 'Drivers of unleaded petrol vehicles should not feel short changed _ what we are seeing is the diesel pump price coming down to a level closer to what it should be due to the effects of greater refining capacity in the Middle East. 'However, if retailers are buying unleaded and diesel in for a similar price, it is right that they are sold on to motorists at a similar price, or cheaper if the diesel wholesale price is lower.î
