DONEGAL has been named the most expensive county for petrol.
The Automobile Association’s nationwide pump price poll found hard-up motorists in Donegal have to fork out the most for a tank of petrol.
The average cost in the county is 128.1 cent per litre — 1.6c more than the national average.
Some garages in the border county have the highest fill-up charges in the country — demanding 131.9c per litre.
AA Director of Consumer Affairs Conor Faughnan said Donegal drivers should shop around before filling up.
He warned: “Border counties tend to be more expensive to fill up in by virtue of geography.
“It is common for motorists to cross the border in an effort to dodge the UK’s considerably higher pump prices.
“That coupled with its rural nature make it unsurprising that Donegal is a relatively expensive county.
“It is certainly worth shopping around for the best deal as there is a significant difference of 7.1 cent per litre in the same county.
“To be fair there are garages in Donegal where cheaper prices can be found, and indeed some that are very good value.
“On the whole though we did find prices in these counties to be a bit ahead of the norm.
“With prices falling as they are at the moment it can happen that garages that are less busy get less frequent deliveries and can appear slow to drop their prices.
“The message to drivers is to be canny about this and to shop around.”
Meanwhile, Mayo and Roscommon are cheapest for diesel, with an average of 106.5c.
But the AA also found a service station in both counties selling fuel for just 99.9c per litre.
Mayo was also cheapest for petrol, coming in at an average of 122.7.
