How you can save on fuel costs
Drive smoothly
Fuel efficiency can vary as much as 45% between different drivers using identical cars.
Rapid acceleration, and constant acceleration and braking uses much more fuel than gently accelerating to cruising speed and then maintaining a steady speed.
Driving smoothly means:
- look beyond the car ahead and anticipate traffic conditions.
- keep a buffer zone between you and the car ahead to avoid unnecessary acceleration and braking.
- When slowing down, you lift off the accelerator early and take advantage of the car's momentum. Getting back to cruising speed from rolling uses far less petrol than stopping and then starting again.
Reduce your speed
Speed kills economy - a car travelling at 110 km/h can use 30% more fuel than at 80km/h.
Pump up those tyres
10% under-inflation of tyres can increase fuel consumption by 10% or more.
Check tyre pressures at least once a month. This should only be done when the tyres are cold; and always replace the valve cap to keep out dust and water. Recommended tyre pressures are shown on a plaque, which is usually on the edge of the driver's door, or inside the glovebox. Inflate your vehicle's tyres to the highest pressure recommended by the manufacturer and make sure your wheels are properly aligned (remember to keep your spare tyre inflated as well). Looking after your tyres will not only reduce your fuel consumption it will also extend tyre life and improve your car’s handling.
Service your vehicle regularly
Having a well-tuned engine can save 10% on fuel consumption.
Cars should be regularly serviced and properly tuned in accordance with the service manual (usually every six months or 10,000km, whichever occurs first). Note that the time is just as important as the distance.
Fortnightly checks of oil, coolant, brake fluid and the battery are an important part of good maintenance (see your car owner's handbook for details). Each of these is important for the efficient functioning of the vehicle. Any leaks should be repaired as soon as possible to avoid contamination of water and soil.
Warning lights on the car instrument panel should be heeded. Any changes to the sound or feel of your car, such as a rattle or unusual movement in steering or pedals can be an early indication of a problem and needs to be checked.
Plan your trips
The most effective way to save fuel is to use your vehicle less.
Think about your travel needs prior to your travel. Planned travel decisions will result in fewer trips and more efficient/cheaper travel than unplanned decisions made "on the go". Some travel planning tips include:
- Plan to do a number of errands in one trip rather than several trips and save time and fuel
- Walk or cycle – aside from being free there’s the additional benefit of getting some exercise
- Avoid peak-hour traffic whenever possible
- Use public transport – it’s often cheaper and allows you to do other things whilst in transit
