There were queues on the Wrekin Retail Park as motorists waited their turn on the remaining pumps at Tesco's petrol station.
Shropshire Fire and Rescue was sent to the scene at about 3.30pm to assist in the clean-up. The diesel on the forecourt was absorbed with sand.
Reporter Robert Smith captured this video:
The firefighters, from Wellington, were in the area until about 4.15pm.
