A number of Donegal garages have smashed through the €2 a litre barrier for diesel.
Some service stations across a number of towns in the county including Letterkenny, Ballyshannon, Ardara, Donegal Town and Bridgend passed the barrier over the weekend following further price hikes.
A sample of a number of garages shows that a litre of diesel now costs an average of €2.092.
And petrol is not much further behind with many garages charging €1.89c a litre of petrol.
Garages say they are not to blame and that the price hikes are coming from suppliers as well as tax from central Government.
A recent decision to cut VAT on fuel by the Irish Government has effectively been wiped out due to the rising prices.
The Automobile Association has also warned that the price of fuel could rise even further over the summer months.
Some larger cars and jeeps are now costing over €140 to fill.
The recent prices hikes have increased the cost of running the average family car by more than €600 a year.
