Fuel supplies at gas stations in London and the South East are lower than in the rest of Britain.
Figures from the Department of Business, Energy and Industrial Strategy showed filling station storage tanks in the capital were only 27% full at the end of the day on Sunday, compared to 37% across Britain.
The situation was slightly better in the Southeast (33%).
Average stock levels in the UK fell to 15% on 25 September, two days after panic buying began.
In early 2020 – before demand was hit by coronavirus restrictions – stock levels averaged around 43%.
The figures also show that fuel sales dropped from an average of 35,900 liters per gas station on September 24 to 11,600 liters on Sunday.
Luke Bosdet, AA’s spokesperson for fuel prices, said the statistics were that the crisis lasted 17 days and it wasn’t until Sunday when “normalcy” returned.
He continued: “The persistence of this road fuel spree has come as a surprise, and it will be necessary to reschedule future reactions to such events, taking into account the immediate impact of messaging and social media when a forecourt is refueled, and whether spending limits are sufficient when the cost of fuel is this high.
“As soon as a gas station was delivered, it was clear that the earth and his wife had landed on it to fill it up.
“Also, at around 136p per liter, a £30 cap on fuel sales bought just 22 liters of petrol in a typical 55 liter tank.”
