Supermarket Fuel Saves Drivers 3.4p Per Litre on Unleaded

Supermarket forecourts are selling unleaded petrol noticeably cheaper than the national average right now, and for most drivers that difference adds up to a real saving every time they fill up. Official UK fuel price data covering 7,780 forecourts across the country puts the average price of E10 unleaded at 154.1p per litre, roughly £7.01 a gallon, while the 1,484 supermarket sites included in the same dataset average 150.7p per litre, or about £6.85 a gallon.

That gap of 3.4p per litre might not sound much on a single purchase, but on a typical 50-litre fill it works out to £1.70 saved each visit. Fill up once a week and you are looking at more than £88 over a year just by choosing a supermarket pump over an independent or motorway forecourt.

Diesel drivers are paying considerably more regardless of where they fill up. The national average for diesel currently sits at 169.7p per litre according to the same official figures, which is more than 15p above the unleaded average. Anyone running a diesel vehicle should factor that into their running costs and keep an eye on whether supermarket sites offer a similar discount on diesel in their area.

If you want to get more from every tankful, simple habits such as keeping your tyres properly inflated, avoiding unnecessary weight in the boot, and not leaving the engine idling can all reduce how often you need to fill up in the first place.
