Preparations are due to start today for talks to resolve the fuel tanker drivers' dispute which lead to panic petrol buying across the UK.
The conciliation service Acas will be briefed in an attempt to get a deal to end a threatened strike.
The Unite union, which represents over 2,000 tanker drivers, are calling for strike action over health and safety issues.
The talks come after ministers faced intense criticism for urging motorists to keep their petrol tanks topped up, prompting a wave of panic-buying at filling stations across the country.
Queues have now shortened on petrol forecourts after the government issued new advice, telling motorists there was "no urgency" to top up tanks, after Unite ruled out the threat of strikes over Easter.
On Sunday, the Foreign Secretary William Hague defended the Government's handling of a possible strike.
He told the BBC's The Andrew Marr Show ministers had been right to warn motorists of the possible threat to fuel supplies.
Mr Hague said:
The latest figures show that the volume of petrol sold has fallen after a high on Thursday.
RMI Petrol, the organisation representing 5,500 independent UK forecourts said that sales of unleaded petrol were up 172% on Thursday but by Saturday this increase had fallen to 18%.
An AA spokesman said panic buying had "dramatically dropped", adding: "I think where there has been a problem, it has been waiting for petrol stations to be replenished and some drivers have interpreted that as a continued problem."
Meanwhile, Labour MPs have called for the resignation of Cabinet Office Minister Francis Maude, who has faced a barrage or criticism from fire experts since advising motorists earlier this week to store jerry cans of fuel in their garages.
Diane Hill, 46, from York, is in a 'critical' condition in hospital with 40% burns after vapours ignited as she decanted petrol from one container to another, setting fire to her clothing.
The Health Secretary Andrew Lansley has dismissed reports that Mr Maude had been urged to resign by two Conservative Cabinet ministers after breaking from the agreed Government line and calling on people to stock up on petrol.
He told Sky News' Murnaghan programme:
