Driving style, cold engine, poor car maintenance, rapid acceleration and incorrect tyre pressure all affect fuel consumption adversely.
By following a few simple tips and suggestions you can reduce your engine's workload, which means it will burn less fuel and produce less CO²:
Starting the Car
Turn the engine on then drive off gently and without delay. This will reduce excessive fuel consumption and pollution.
Maintain your car regularly
A properly maintained car will have good engine lubrication, wheel alignment and well adjusted brakes reducing your fuel consumption.
Tyre Pressure
Tyres 0.5 bar below manufacturers recommended pressure increase wear and fuel consumption by 2-3%. Ensure your tyres are at the manufacturers recommended pressure.
Reading the road
By watching the roads ahead and anticipating any likely problems, your driving style will become smoother, better controlled and be safer for you and other road users.
Maintaining your distance
Safe and economical driving requires you to maintain a sufficient distance behind the car in front - a minimum of 10m for every 15km/h speed. This way you can brake and accelerate more smoothly.
Saving fuel in town
Avoid over-revving the engine and drive in as high a gear as is suitable to road conditions.
Reduce unnecessary drag
Take off unused bike racks or roof boxes and save 15-40%. Use the car’s vents rather than leaving the windows or sun roof open, saving you a further 3-5%.
Even if you only have to wait 30 seconds, it is more economical to switch the engine off and start it again when necessary.
At bends, reducing speed gently and in time and accelerating smoothly when you are halfway through will reduce excessive fuel consumption.
Lower speeds are safer, but driving at high speed (over 80km/h and especially over 100km/h) also uses more fuel and causes more pollution.
The rear window demister being on uses 3-5% more fuel. Remember to switch it off when the window is clear.
