What affects my fuel consumption?

Many factors can have an effect on your car’s fuel consumption including your driving style, traffic conditions, excess weight, roof racks, and the general condition of the car.

Is it better to open a window or use air con?

At motorway speeds the amount of aerodynamic drag caused by an open window is considerable. When you’re going fast and need to cool down, use the air conditioning, otherwise at slower speeds (especially in town) you can use the windows.

What is the most fuel efficient driving style?

Try to be smooth and avoid accelerating harshly, and try to predict the traffic flow to avoid having to stop – it takes a lot more energy to get a car moving than it does to keep it moving. Even with modern stop-start systems you’re still consuming energy when you start moving, and that energy ultimately has to come from the fuel.

How can I improve my fuel consumption?

Some of the simplest measures can make a big difference. Make sure that your tyres are at the correct pressure and are in good condition, and get your car serviced according to the manufacturer’s recommendations.
