Large queues of commuters took the last litres of unleaded, super unleaded and diesel from Asda's filling station during this morning's rush hour, forcing bosses to put up the 'closed' signs.
A member of staff at the supermarket in Chalfont Way said it is expecting a delivery of fuel within the next few hours.
A nationwide panic was sparked by Cabinet Minister, Francis Maude, yesterday, who announced that motorists should stockpile fuel to prepare for a possible strike by petrol tanker drivers.
Meanwhile the Royal Berkshire Fire and Rescue Service, with its Buckinghamshire and Oxfordshire neighbours is urging the public to ignore Mr Maude's advice about storing petrol in a jerry can at home.
Olaf Baars, Berkshire's Deputy Chief Fire Officer, said: "Petrol is an extremely dangerous, highly flammable, explosive and toxic substance.
"There are laws governing its storage, which require that only very small quantities of petrol are kept in appropriate containers and in a well ventilated, secure building away from your house.
"Our concern is that people may underestimate the dangers and store increased quantities of petrol unsafely, which could lead to devastating fires and even loss of life."
