Diesel prices rising twice the rate of petrol
Average diesel prices are now about 30p per litre more expensive than petrol, according to the latest data from the RAC.
It found that the average price of petrol has risen to 152p per litre, while diesel has escalated to 181p per litre.
The gap between the two fuel types has now reached record levels, with the impact likely to be felt most keenly among fleets operating diesel vans and cars.
Prior the war in Iran, the difference between petrol (133p) and diesel (142p) was less than 10p per litre, while the price gap rose to 24p per litre following the outbreak of the war in Ukraine in late 2022.
However, RAC data has found that diesel prices have risen 27%, or nearly 39p per litre, since the Iran conflict started compared to a 14% increase (19p) for petrol.
Fuel prices
RAC fuel spokesman Simon Williams said: “While average prices of both petrol and diesel have dropped considerably from the all-time highs of the summer, diesel is now a record 17p a litre more expensive than unleaded.
“The gap between the two fuels is normally around 4p a litre but this has widened since Russia invaded Ukraine. Prior to this, diesel had only ever been as much as 11p dearer than petrol back in August 2015.”
