Petrol prices have reached an all-time high today with some stations increasing 91 to 222.9c a litre.
The increase is 1c above the previous high of 221.9c in May 2011.
AA spokesman Mark Stockdale says it's simply down to commodity price fluctuations.
"Not all fuel companies have increased their prices yet, so certainly we'd be urging motorists to shop around if they need to fill up, and take note of who's got lower prices."
An increase in the international price of crude is being used to justify the rise.
Z Energy was the first to hit the new high of 222.9c.
As recently as June, 91 was only 197.9c a litre. Two cents of the rise since then is due to increased fuel taxes.
"While fuel companies seem to have passed on slightly more than the product cost, their importer margin (retail price less costs) has fallen over the same period, although the AA considers it is still within the normal range so there was scope to absorb further cost increases," the AA said in a statement.
