RAC settles debate on if drivers save money getting petrol from Tesco, Sainsbury's, Asda

Motoring experts at the RAC have revealed how drivers could be saving money by filling up at top supermarket brands such as Tesco, Sainsbury's and Asda. Speaking exclusively to Express.co.uk, RAC head of roads policy Simon Williams previously explained that supermarket fuel pumps were the best places to top up their tanks.

The RAC has previously suggested that petrol and diesel could be as much as 4p per litre cheaper at supermarket pumps than at specialist fuel chains. Although supermarkets were cheaper, the RAC admitted that there was little difference between the major stores on the road.

Simon said: "Fuel is generally 3-4p cheaper at supermarkets compared to the UK average. Over the years, the supermarkets have built a reputation for selling good-value fuel, and as a result, they dominate the market. As they sell so much fuel, they are also better placed to take advantage of wholesale price dips than other retailers who don't buy new supplies as often.

"There is very little difference between the supermarkets on average, although drivers can find significant differences from area to area, particularly if there's strong competition from independent retailers."

According to data from RAC Fuel Watch, Asda has the cheapest supermarket fuel in the UK, with prices at just 131.7p per litre on average. Morrisons was next with average petrol costs at 131.9p per litre, followed by Sainsbury;s (132.1p) and Tesco (132.2p),

Across all brands, the average spend was 132.0p, much lower than fuel brands such as Esso, BP, Jet and Shell which came in at an average of 136.3p per litre.

It's good to see prices at the pumps have fallen slightly in October, reversing the increase drivers experienced in September. It comes after a good month for combustion owners in October, with petrol and diesel costs on the decline.

The cost of petrol has dropped to 134.97p per litre by the start of November, down by 0.58p from the 135.55p recorded at the beginning of October.

Mr Williams added: "Our analysis shows that while it's cheaper on average to fill up at supermarkets, it's also worth seeking out low-priced independent forecourts that can offer great value petrol and diesel.

"The best advice is to keep a close eye out for low prices on your normal routes or, better still, use the myRAC app to search for the best prices in your area."
