Motorists could save more than £800 a year by following four simple fuel-saving tips.
A survey, which was commissioned by Ford, has identified the tricks of the trade, which could help save as much as 33 per cent on fuel.
They encourage drivers to remove a rooftop cargo box when not being used to save 20 per cent, shop around for fuel (seven per cent), check tyre pressures monthly (four per cent) and take out excess weight from inside the car (two per cent).
The survey of 5,700 people from across Europe showed that 76 per cent do not regularly check tyres, 38 per cent never remove their roof storage equipment, 18 per cent never shop around for cheapest fuel and 17 per cent always leave extra items in the car.
The poll also revealed further opportunities to cut fuel consumption as 71 per cent of drivers admit breaking speed limits, 42 per cent never use the most economical route, 39 per cent drive aggressively and 14 per cent leave air conditioning on all the time.
Ford commissioned the survey of drivers from the UK, France, Germany, Italy and Spain to identify the opportunity for changes in driver behaviour to affect fuel bills.
It found that with people on average spending almost £2,500 on fuel each year, bills could be cut by £820.
