Asda has announced a cut on petrol and diesel prices in an effort to help motorists save money.

The move has been introduced at all of Asda's 323 petrol stations in the UK - including Penryn.

Drivers will pay on average 174ppl for unleaded and 185ppl for diesel when filling up at Asda. The latest price reduction follows a cut of 4ppl earlier in the week, meaning the supermarket has reduced fuel prices by 9ppl on unleaded and 7ppl on diesel since the start of the week.

AA fuel price spokesman Luke Bosdet commented on the drop, saying: "Asda's price move is impressive, in effect cutting 10p a litre off the UK average price of petrol. That's potentially a fiver off a tank for those filling up this weekend, compared to the artificially-high prices on too many major retailer forecourts and in too many towns.

"First, it was a few dozen small independent forecourts showing up the big boys. Now, Asda has called them out with on average a fiver off the cost of a tank of petrol. Latest UK pump price averages have petrol at 184.50p a litre (27th July)."
