The fuel duty freeze of the last three years has made "little impact" on the wallets of cash strapped motorists, the RAC has said.
RAC Foundation director Professor Stephen Glaister called on the Chancellor to "go beyond his promise" to freeze fuel duty and "cut the rate further" in the 2014 budget, scheduled for March 19.
British drivers who use diesel to fuel their vehicles face the highest rate of tax in Europe, the RAC Foundation has found.
The only country more costly than the UK for motorists filling up their cars with petrol is Sweden, the charity said.
Its figures showed that tax accounts for 59% of the price of diesel in the UK, with Sweden (56%) second and Italy (55%) third.
As much as 61% of the price of petrol in the UK is down to tax, with Swedes (62%) paying the most in tax and the Netherlands (61%) paying the same.
In contrast, of 28 European countries surveyed, Luxembourg's drivers fork out the least amount in tax which accounts for only 41% of the total price.
The planned 2p fuel duty rise due in September is now cancelled. It is a hot topic but has the Chancellor gained political credit for cancelling it for past two years?
George Osborne has confirmed the 3p rise in fuel duty has been cancelled and not just postponed.
Analysis of division lists showed that no Conservative MPs backed the Labour motion to postpone the 3p fuel duty rise in January.
82% of people surveyed for the ITV News Index by ComRes say they oppose a rise in fuel duty.
73% of those asked said they would be angry if a fuel duty rise goes ahead.
Four in five of those surveyed think a fuel duty rise will make the Government look out of touch and two-thirds believe a rise will make a material difference to their household’s income.
Despite being a staunch opponent of a rise in fuel duty costs, Conservative MP Robert Halfon will vote later against a Labour motion calling for January's 3p per litre rise to be delayed.
He told ITV News his Harlow constituents would understand his course of action is still geared towards keeping the cost down.
Fair Fuel UK campaigner and motorist presenter Quentin Willson has told ITV News 35,000 jobs will be saved if the Chancellor chooses, as expected, to not pursue the 3p fuel duty rise.
Prime Minister David Cameron's official spokesman earlier declined to comment on whether the Government might back down on the 3p fuel duty rise.
He said the controversial rise was a matter for the Chancellor.
