Tires
Did you know that a flat increase your fuel consumption? Driving with soft tyres can add up to 2% to your fuel bills. So keep your tyres inflated to the correct level and save.
Air conditioning
Air conditioning uses up to 25% more fuel. Switch it off and open your air vents instead, or just have the window down.
Service your car
Inefficient, under-serviced engines can reduce fuel economy by 10% or more. Similarly, have the oil in your car changed regularly. Having clean oil reduces the wear and tear on the engine.
A light load
The lighter the car is the less petrol needed to move it. Remove roof racks, carriers and removable seats when they are not in use. Also keep the boot empty as often as possible.
Avoid traffic
Obviously, where possible. Small cars stuck in traffic jams use up a litre of petrol every 60 minutes.
