More than a quarter of motorists are restricting the amount they spend when they fill up their car due to high fuel prices, an AA/Populus survey showed today.
Women are restricting their petrol spending more than men, with budget-tightening happening the most in Northern Ireland, north-west England and Wales.
Of the 15,860 AA members surveyed, 14% paid a set amount on their credit card for fuel and 14% set a limit when they paid cash.
The number setting limits on fuel payment rises to 44% among unskilled workers, long-term unemployed and pensioners.
Only 21% from the top socio-economic group are limiting what they pay at the pumps.
Among those budgeting a set amount for buying fuel, 23% have had to raise their limit while 13% have cut back on their spending.
AA president Edmund King said: "This AA research is a stunning indication of just how badly fuel prices are affecting so many drivers across the UK."
