Drivers have been issued an urgent warning if they plan on filling up with petrol or diesel within the next two weeks.
It comes as drivers could see diesel prices fall in the coming weeks, according to Birmingham Live. However, it will require retailers to reflect a drop in wholesale prices at the pumps, with the RAC revealing that diesel drivers are currently charged an extra 20p over those who use petrol.
Despite there being 'little difference' in their prices on the wholesale market, diesel drivers are spending £92 to fill the average tank, with a family petrol car setting motorists back £81.

Over the next 14 days however, the RAC have said diesel drivers may see prices slashed.
Their research found that diesel wholesale prices - the amount that retailers pay for fuel - were just 6p per litre more than petrol last week. But this is not being reflected at stations, with 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.
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."
