Yesterday in Sandhurst: petrol 162.9, diesel 175.9.

Blame Walmart - for many decades their Asda subsidiary acted as a price brake on the whole industry and kept prices competitive although they obviously fluctuated due to outside factors - in February 2021, Walmart sold most of their holding in Asda to the Issa brothers who also own Euro Garages (EG Group) who are a major business in UK fuel forecourts and no longer keep prices low and are a major reason for the increase in prices over the last year.

In what way are they not keeping the Asda fuel prices low? And all the other supermarkets are lower priced so not sure I can see that Asada being sold makes a differenece?

Maybe they are saying that if they are not owned by ASDA, they no longer subsidise them to get people into the supermarket, though I suspect this isn't so much of a thing anyway because of online sales.

Saying that, whenever I've looked up the prices via the Petrol Prices website where I happen to be, ASDA (in the absence of a Cosco) is either the cheapest or in the top three for best price. Probably because they are (filling stations at a supermarket) unmanned.

At one time it was Asda policy to have a single price for each fuel type across all their sites. Others price differentially according to local market and competition.

Fuel at Sainsburys in Northampton (no Asda filling station) was for years consistently three or four pence a litre more than 30 miles up the road at it's Leicester Fosse park site where there was an Asda adjacent.
