Motorists today accused some petrol stations in Britain of taking advantage of their desperation to fill up their cars by putting up prices as panic buying continued.
Some drivers including children's TV star Paul Chuckle even claimed that the cost was different to that displayed outside or went up while they were waiting in queues.
Fuel experts said they expect pump prices will rise 3 to 10p per litre over the next few weeks - with the biggest hikes in recent days happening in rural areas.
Dozens of cars snaked back in lines from petrol stations across the country over the weekend, swallowing up supplies and forcing many petrol stations to simply close.
Drivers also claimed diesel prices had gone up by as much as 8p in a few days, while others said some petrol stations were turning off their digital price display boards.
But the issue does not appear to be UK-wide - with today's average price at 135.6p, which is roughly level with the latest official Government figure of 134.86p last week.
Howard Cox, founder of the FairFuelUK Campaign, told MailOnline: ‘On average I am hearing via FairFuelUK Supporters, that price increases, 5p to 10p increases are the norm in the last few days.
‘For example I’m hearing in Ashford, Kent they were all queuing up for fuel at one filling station on the A20 in Maidstone on Saturday, they put their prices up to £1.48 a litre to profiteer from it.
‘Shell in particular are selling at £1.479, Texaco £1.459. Supermarkets remain at about £1.33. Ironically it seems petrol is the one being hiked most hitting ordinary families, with diesel less so.
‘Several garages have contacted FairFuelUK in confidence, saying their greedy wholesalers are pushing up bulk supply prices, not based on oil costs, but because of this latest panic demand.
‘Opportunism at its lowest. Some are saying there will have to be longer term rationing causing more conflicts at their pumps. Totally unnecessary, as there is no fuel supply issue, just that perennial pre warned driver shortage.’
