PETROL prices are on the rise again as the cost of oil surges – fuelling yet more misery for motorists at the pumps.

A couple of pence a litre has been added to the cost of diesel and unleaded over the last two days, as average petrol prices pass the 130p per litre mark for the first time.

With a duty rise coming next month, and instability in the middle east and north Africa set to continue impacting oil prices, some are warning of another 8p per litre in the near future.

A year ago, the average pump price of petrol was 112.74p and diesel 113.79p – meaning that filling a typical 50-litre petrol tank now costs £8.65 more than a year ago.

RAC motoring strategist Adrian Tink said petrol prices could “increase by another 8p a litre in the near future”.

He added: “This kind of rise will seriously impact on people's car use, many of whom have no other option but to travel by car.”

Edmund King, president of motoring group the AA, has urged the Chancellor to abandon the proposed duty hike set to hit next month, and “seriously consider reducing fuel duty to stabilise prices”.

He added: “The government must bite the bullet and act to stop fuel prices from fuelling inflation and driving people off the roads.”

Andrew Trotter, who owns Poole-based AET Transport services, said fuel bills for his business were up £2,000 a week since Christmas.

He said: “They can’t keep bleeding the companies. They’ve got to look at it.”

Alan Vaughan, owner of 1st Choice Removals in Magna Road, agreed. His business spends up to £3,000 a month on fuel and any increases have a big impact.

“I think they ought to cut the duty a bit when the prices go up to level it out a bit,” he added.

“With the government putting their bill on top all the time it makes it ridiculous.

“It’s not just us – it’s supermarket lorries, farmers, all paying lots more – it’s just going to push the prices up on everything.”
