Diesel is now at its second-highest monthly average price on record, the latest fuel price survey from AA Ireland shows.

The AA said the average price for petrol across the country remains at €1.84 per litre, with diesel now at €2.02 per litre, 4% more expensive than last month.

Petrol is on average 11% more expensive than in October 2021, with diesel just under 30% more expensive.

The AA's figures shows it now costs the average motorist with a petrol car a total of €2,210 to fill it, annually, at current fuel prices - €219 more than the same time last year.

It costs the average motorist with a diesel car €2,020 to fill it, annually, at current fuel prices, €126 more than in October 2021.

It is thought that a surplus in petrol production and a deficit in diesel production is accounting for the differences in prices.

"We have seen quite a spike in the price of diesel in the last month, even though petrol prices have remains largely stagnant over the same period," said AA Ireland's head of communications Paddy Comyn.

"Sales of diesel cars were very much in the majority from 2008 until quite recently, so these high fuel prices will be affecting large amounts of motorists nationally, at a time when energy prices are rising across the board," he added.
