The poll of more than 18,000 AA members, conducted last month, showed that just seven per cent were feeling more relaxed about prices at the pump and using their car more than a year ago.
And as many as 57 per cent said they were still in a car-travel rut and were adopting fuel-saving techniques.
The survey also showed that 18 per cent had replaced their car in the last 12 months with a more fuel-efficient one.
The AA highlighted government figures which showed that petrol sales in March fell to a record low of 1.367 billion litres despite average petrol prices dipping to around 129.5p a litre, which was 10p lower than in March 2013.
AA president Edmund King said: "The fragility of driver and family budgets is clear to see. Years of sky-high petrol and diesel prices have taught drivers how to balance their spending by regulating their car use - even when the financial pressure isn't coming from the pump."
