The latest Santander 123 Card Fuel Survey finds that a car with a 70–litre tank is now £97.37 to fill following a 5.5% increase (7.3 pence per litre) in the average UK petrol price in just two months. And some parts of the UK have seen a 9% rise in the cost of unleaded over the same period.

Santander analysed the average price per litre of premium unleaded fuel in every UK town between 4th January and 11th March 2013, and found that the most expensive place in the UK to refuel is Dumfries, Scotland where prices average 145.9 ppl, meaning owners of vehicles with 70–litre tanks will pay £102.13 to fill up.  Drivers of family vehicles in Durham should also expect to pay over £100 to fill their tanks, at an average of £100.03. In contrast, Torquay is the least expensive place in the country to buy petrol, at an average of 135.9 ppl, or £95.13 for a full tank.

The biggest increases since January of this year have been seen in Paisley, Durham and Hereford, where motorists pay 9% more for unleaded fuel than just two months ago.
