New figures shows that drivers have been hit yet again by an 8p per litre price hike in diesel in September which is the fifth largest monthly rise in 23 years.
Petrol rose by almost 5p per litre from 152.5p to 157.0p and the RAC has said this come amid oil prices have risen after oil producer group OPEC+ has restricted global supply.
RAC fuel spokesman Simon Williams said: “Drivers are sadly really starting to suffer again at the pumps. There’s little respite whichever fuel drivers use.
“Our analysis of RAC Fuel Watch wholesale and retail data shows that petrol is currently overpriced by around 7p a litre, although the price of diesel is likely to go up further still in the coming weeks.
“It’s worrying that retailer margin across the UK is higher for petrol than it should be considering the big four supermarkets were told off by the Competition and Markets Authority for overcharging drivers by £900 million in 2022.
“While many have voluntarily started to publish their prices ahead of being mandated to in law, we still have a situation where wholesale price changes aren’t being fairly reflected on the forecourt.”
