Where is the cheapest supermarket to fill your car up with petrol in Sheffield – and the most expensive?

But the pricing of unleaded and diesel is a complicated affair, involving competition between retailers, taxes and the wholesale cost of oil – meaning it can be quite a hunt to find a place to fill up for less.

However, the website PetrolPrices.com ranks the going rate for different forecourts in particular areas, relying on reports from real-life drivers.

According to its users, the cheapest petrol station to fill up a tank with unleaded in Sheffield is at Costco off the Parkway, where on November 25 the price was 106.7p per litre.

This facility is exclusive to Costco members though. Users of PetrolPrices.com reported that Asda at Manor Top was the second least expensive place for unleaded, at 107.7p per litre on November 24.

The most costly location for unleaded in Sheffield, according to the website, is the Shell garage on Netherthorpe Road, where the price was 116.9p per litre on November 25.

For diesel, meanwhile, the cheapest petrol station listed is the Manor Top Asda, where the pump price was 108.7p per litre on November 26.

Again the website’s most costly location for diesel in Sheffield is Shell on Netherthorpe Road, where the price was 121.9p per litre on November 25..

Breakdown and insurance company the RAC has issued a guide to motorists with tips on finding the cheapest fuel. It recommends that people become familiar with the filling stations close to where they live and work, and take advantage of supermarket ‘price wars’.

“Supermarkets – as well as other fuel retailers – run loyalty card schemes, and while they might clog up your purse or wallet, they can come in handy in cutting fuel costs. The more you fill up, the more points you’ll accrue – you can then exchange these for vouchers off your next fill-up,” the RAC says.

“Some credit card companies offer cashback for spending money at filling stations. While it might not actually save you money at the pumps, it will offset higher petrol or diesel prices by putting something back in your account. Just remember to pay off your account within the month or savings will be cancelled out.

“However, the main way to save money on fuel is to drive efficiently.”
