BOLTON’S most affordable place to fill up your car is more than 17 pence per litre cheaper than the town’s most expensive petrol station.

Petrol price database website, petrolprices.com, reveals that the average price of petrol at the 77 petrol stations within a 10 mile radius of the BL1 postcode is 102.2 pence per litre.

Morrisons in Black Horse Street, Bolton, at 99.7 pence per litre closely follows Asda in Atherleigh Way, Leigh, at 99.6 pence per litre, as the cheapest place to fill up with unleaded in town.

The latter is 17.3 pence per litre cheaper than the most expensive place to fill up, the name of which isn’t revealed by petrolprices.com

Elsewhere, supermarkets Morrisons and Asda dominate the top ten cheapest places to fill up.

For diesel, Asda's Horwich store is the cheapest place to fill up, with a price of 96.7 pence per litre.

Those wanting some high-octane super unleaded will find it for 104.9 pence per litre at Sainsbury's in Bolton, Westhoughton and Leigh and Tesco in Walkden and Horwich.

Meanwhile, LPG is cheapest at Gordons Britannia Service Station in Kay Street, where it costs 53.9 pence per litre.

The current average price of fuel in Bolton is nearly six pence per litre cheaper than the national average at the same point last year – when it cost 108.1 pence per litre to fill up with unleaded.

While the falling price of oil has meant good news for motorists at the pumps, the good times are not expected to last.

RAC fuel spokesman Simon Williams said: “Motorists have seen petrol and diesel prices reach their lowest points since 2009. January saw the oil price go into free fall with talk of a barrel dropping to $20 and possibly even to $10, but since the low of $26 a barrel the market has started to creep back up.

“If this continues for a sustained period, wholesale costs will rise further which will in turn lead to pump price increases.

“However, the oil market is notoriously volatile, even in more stable economic times, so it’s still possible that the price could drop back again.”

He added: “The other factor which is not helping the situation from a motorist’s perspective is the fact that the pound has weakened significantly against the dollar from $1.47 at the beginning of January to $1.42 by the end.

“This has undermined some of the benefit of the falling oil price and, with oil traded in dollars, this could prove to be even more harmful if the pound continues to lose value against the dollar while the oil price goes up.”
