Some petrol station forecourts were closed on Saturday, with long queues at garages still with working unleaded pumps.
Motorists are being urged not to fill up unnecessarily, with panic-buying blamed by the head of the AA for local shortages
In Upper Street, Islington, a queue stretched back from the Shell garage past the town hall before businesses had opened.
At the large Esso at the top of Archway Road, cones were out to stop vehicles entering, with all pumps closed. A sign at the Shell in Holloway Road said: "Sorry, fuel is temporarily unavailable."
Further up North Hill, Highgate, there was a queue for one working unleaded pump.
Edmund King, president of the AA, told BBC Breakfast on Saturday that panic-buying rather than supply chain issues is driving the shortage of fuel at some stations.
He said the problem should pass in a matter of days if drivers stick to filling up when they need it, adding “there is plenty of fuel at source”.

“If you think about it, 30 million cars out there, if they’ve all got half a tank [and] if they all rush out to fill up the rest of the tank and the tank is about 60 litres, that will put a strain on the system,” he said.
On Friday transport secretary Grant Shapps tried to dissuade drivers from panic buying petrol, telling motorists that they should "carry on as normal".
