IT now costs around £100 for motorists to fill up a family diesel car.
Price hikes at many forecourts across the north have seen the cost of filling an average 55-litre diesel car hit £100 for the first time.
It comes as the RAC warned that "drivers are feeling never before seen pain at the pumps" with figures showing that the average price of a litre of both petrol and diesel has hit new highs.
The price of a litre of unleaded at some petrol stations was yesterday as high as 182.9 pence at the Go forecourt near Yorkgate in Belfast, while the diesel cost at a Maxol garage on the Antrim Road in the city was 180.9 pence per litre.
This means that drivers of the average 55-litre diesel cars, such as a Nissan Qashqai or an Audi A3, face a £100 bill every time they fill up.
For those owning a Peugeot 308 or BMW 3 Series, the costs to fill a 60 litre tank is even more.
It comes amid the escalating effects of rising energy prices over the past few months, with prices increasing dramatically as a result of the conflict between Russia and Ukraine.
But drivers have been advised to shop around for cheaper prices, although the savings only represent around £2 to £3.
At a BP filling station in south Belfast yesterday, unleaded petrol was 171.9p, while diesel was priced at 181.9 pence. The unleaded price at a Nicholl garage in Carryduff was also 171.9 pence, with diesel at 179.9 pence.
Unleaded prices in Temple, Co Down were 177.9 pence and diesel was 179.9 pence.
