Remove excess weight, and get rid of any rubbish in the car

Air conditioning uses fuel. But having the windows down causes drag, which uses up fuel too. Well, here’s what to do. At low speeds, open the window – the fuel used to compensate for drag is less than the fuel used to power your air con. But when driving on the motorway, it’s the other way around. So turn on the climate control and roll the windows up

Your driving style can have a big impact on how much petrol or diesel you use. Try to keep your driving smooth. Gentle acceleration and using the highest safe gear will use less fuel
