NextFin News - Drivers in Stourbridge are facing a stark 27p-per-litre "diesel premium" as local fuel prices diverge sharply from national averages, with Morrisons in Kingswinford emerging as the region's most aggressive price leader for petrol. As of March 21, 2026, the cheapest unleaded petrol in the Stourbridge area is priced at 137.9p per litre, while the most affordable diesel has climbed to 157.9p at Tesco Cradley Heath Extra. This 20p gap between the two fuel types locally is actually narrower than the national trend, where diesel has surged to an average of 161.20p compared to petrol’s 141.74p, according to data from heycar UK.
The pricing landscape in Stourbridge reveals a highly competitive "supermarket cluster" that is currently undercutting major oil-brand stations. Morrisons Kingswinford holds a 2p advantage over its nearest rivals, including BP on Pedmore Road and Shell on Dudley Road, both of which are holding steady at 139.9p for unleaded. This local floor of 137.9p sits nearly 4p below the current UK national average, suggesting that the price war among retailers in the West Midlands remains more intense than in other parts of the country. However, the luxury of choice is disappearing for diesel drivers, who are seeing prices at some local Esso and BP stations reach as high as 164.9p, a significant markup for those failing to shop around.
The widening disparity between petrol and diesel costs is a direct reflection of global supply constraints and the ongoing impact of geopolitical uncertainty on refined product markets. While crude oil prices dictate the baseline, the specific shortage of refining capacity for middle distillates has kept diesel prices stubbornly high. According to Fuel Finder UK, supermarket petrol remains on average 5.1p cheaper per litre than premium brands, a trend that is vividly illustrated in Stourbridge where Sainsbury’s Amblecote and Asda Dudley are consistently appearing in the top ten cheapest lists for both fuel types. For a standard 55-litre family car, the difference between filling up at Morrisons Kingswinford versus a high-end Esso station now represents a saving of nearly £4 per tank.
Retailers are operating on razor-thin margins as wholesale costs fluctuate. The current stability at the 139.9p mark for many Stourbridge stations suggests a psychological price floor that retailers are hesitant to break. While petrol prices have seen a modest rise of approximately 9.8p over the last quarter, diesel has outpaced it significantly, jumping by over 20p in the same period. This trend is likely to persist as long as global demand for heating oil and industrial diesel remains robust, keeping the pressure on local pumps. For now, the strategy for Stourbridge motorists is clear: the short drive to Kingswinford or Cradley Heath offers the only meaningful shield against the rising tide of national fuel inflation.
