Experts at the RAC are warning that people who fill their vehicles up with diesel could be paying far more at the pumps than they should be. Diesel is being sold for around 17p a litre more on average than petrol at forecourts across the country - despite wholesale prices for both fuels being virtually identical.
According to RAC Fuel Watch, the average price of a litre of petrol is 146.63p. Diesel, meanwhile, is priced at 164.26p typically, reports the Mirror.
But according to the RAC, both fuels are selling for around 114.5p on the wholesale market. RAC fuel spokesman Simon Williams described the fuel price disparity as "absolutely shocking".
