Darlaston kept the cheapest standard E10 petrol in Stone at the end of Wednesday 7 October, priced at 168.9p a litre. Three other Stone forecourts — Morrisons, Fairway Esso and Fillybrook BP — were all charging 169.9p, meaning four of the town's five stations were within 1p of each other.

For a typical 55-litre fill, Darlaston's price works out at around £92.90, compared with £95.65 at Walton Shell. This represents a saving of £2.75.

Darlaston increased its petrol from 167.9p to 168.9p on Thursday 1 October. On the same day, Walton Shell moved in the opposite direction, reducing its standard petrol from 174.9p to 173.9p. Prices at Morrisons, Fairway and Fillybrook remained unchanged throughout the week.

The price gap between Stone's cheapest and most expensive standard petrol narrowed from 7p the previous week to 5p. Darlaston's 1p advantage over the next lowest price is equivalent to 55p on a full 55-litre tank. Within the wider 12-mile search area, the next lowest price was also 169.9p, found at Asda Trent Express, meaning motorists do not need to leave Stone to find the cheapest petrol locally.

Diesel prices narrow in Stone

Stone diesel prices have become more competitive. Four forecourts — Darlaston, Morrisons, Fairway and Fillybrook — are all now charging 197.9p a litre. Walton Shell is just 1p higher at 198.9p. The difference between Stone's cheapest and most expensive standard diesel is only 1p a litre, or 55p on 55 litres.

Darlaston was the only Stone forecourt to change its diesel price during the week, increasing from 195.9p to 196.9p on Thursday and then to 197.9p on Friday.

However, there are larger savings available outside Stone. Asda Wolstanton offered the cheapest standard diesel in the wider search area at 191.7p a litre — 6.2p below the Stone forecourts at 197.9p. On 55 litres, this represents a saving of around £3.41, although drivers would need to factor in travel costs.
