Engine
Maintain the engine in peak mechanical condition by having it serviced regularly in
accordance with the Maintenance schedule, in Chapter 12. This will ensure items such
as the spark plugs, air cleaner, engine idle speed etc. are maintained for minimum fuel
usage and peak engine performance.
Tyre pressure
Keep the tyres at the recommended pressures. Under-inflated tyres create extra rolling
resistance which contributes to increased fuel consumption, refer Chapter 7.
Incorrect tyre pressures can also cause uneven and premature tyre wear.
Wheel alignment
Maintain correct front wheel alignment. Incorrect alignment makes the front wheels
drag, which increases fuel consumption and causes uneven and premature tyre wear.
Warm ups and idling
Avoid long engine warm ups. They are unnecessary and waste fuel. An engine takes
approximately five minutes to reach its efficient operating temperature and it does this
most effectively when driving.
You should also avoid long engine idling. If your have to wait for more than a couple of
minutes turn off the engine to conserve fuel.
Accelerating, driving and braking
Accelerate gently - avoid rapid starts, sudden bursts of speed and full throttle
acceleration - they're certain fuel wasters.
Drive the car at steady speeds where possible (after run-in).
Riding the brake
Do not rest your foot on the brake pedal when you do not intend to brake, as this can
overheat the brakes, increase brake pad wear, damage the brakes and waste fuel.
Air conditioning
Turn off the air conditioning when not required. However, once every two weeks, with
the engine running, switch the air conditioner on for 5 to 1 0 minutes to lubricate seals
(even in winter).
