The group to suffer most from the recent petrol-price hikes has been drivers filling up at motorway service stations, new research by the RAC shows.
The study found that motorway prices have been, on average, nearly 10p a litre higher than supermarket forecourts, which are often located just off motorways.
The average price of a litre of petrol at motorway service stations has been 120.9p, while supermarket prices have been almost 10p cheaper, at 111.2p a litre. The price difference means that, based on an average-sized fuel tank, drivers filling right up at motorway pumps have paid £5.26 more than those opting for supermarket forecourts.
RAC spokeswoman Louise Zucchi said: "Drivers are getting a raw deal. Most service stations have the infrastructure and buying power of supermarkets like Asda - which led the recent price cuts at the supermarket pumps and has now introduced a fuel pricing policy - but they don't seem to be using that commercial strength to help motorists.
"We hope motorway service station operators will consider what more they could do to ease the pain at the pumps."
She added: "By spending a couple of extra minutes to come off motorways, drivers really can be quids in by taking advantage of significant fuel savings."
