A new report says that diesel prices could fall in the next two weeks. It comes as wholesale prices for the fuel have dropped.
Diesel car drivers pay close to an upwards of 20p more a litre than petrol car drivers. But over the last month the gap between the wholesale price for the two fuels has shrunk.
The RAC said this could see diesel prices slashed over the next fortnight, BirminghamLive reports. RAC spokesman Simon Williams said: "Drivers of the country’s diesel vehicles have every right to feel hard done by as they’re paying a huge premium for the fuel, which in no way reflects its lower wholesale cost.
"For nearly a month, the gap between wholesale petrol and diesel prices has been less than 10p a litre, and in recent days it has reduced to just 3.5p. Yet average diesel prices at the pumps remain stubbornly high, having fallen by only 2p since the start of February.
"The fact membership-only retailer Costco has been able to cut the average price of a litre of diesel by 4p last week shows what’s possible, but we badly need other fuel retailers to treat drivers of diesel vehicles fairly." It found that diesel's wholesale price - the amount that retailers pay for fuel - was just 6p per litre more than petrol last week.
But a litre of diesel is being sold at an average of around 168p while petrol is just 148p. RAC analysis found that retailers are "subsidising" cheaper petrol by taking a margin of 20p on every litre of diesel they sell.
Latest Government figures show 17.6 million vehicles licensed in the UK are diesel-powered, including the vast majority of vans. That represents 43% of all vehicles on the road.
