US says Europe should ready fuel supplies as Trump threatens diesel ban

An export ban from Russia, also a major supplier of diesel, has added to the pressure on prices.Trump has argued that keeping any surplus barrels of diesel in the US would lower pump prices domestically, offering immediate relief to drivers, truckers, and businesses ahead of the midterm elections.But David Fyfe, chief economist at Argus Media, said cutting off American supply would likely cause international prices to skyrocket.diesel prices have hit an all-time high in the UK, with the latest RAC figures showing average pump prices at 199.79p per litre, up from 142.38pDiesel is harder to refine than gasoline and, because it is used by the haulage industry and in agriculture, it is very difficult to reduce demand.The UK is heavily reliant on imports. Although the four refineries in the UK make more than enough petrol to meet demand, they do not make enough diesel for the country's needs.There were 15.1 million diesel vehicles on UK roads at the end of June, according to the Department for Transport. That is a drop from 15.7 million a year before.There were 9.8 million diesel cars, down year on year from 10.4 million.
