Frequent cold starts and short
distance driving leads to
considerably increased fuel usage.

engine
emissions depend upon the engine,
the type of transmission, the tyre
size, the vehicle weight and many
other factors.
Fuel consumption is affected by the
following factors:
Driving speed and gear
selection
Road speed
The above graph shows how
fuel consumption is affected
by speed and the choice of gears.
Holding on to lower gears to
improve acceleration will result in
significantly higher fuel
consumption.
Traffic and road conditions
Slow moving traffic, uphill driving,
frequent sharp bends and rough
roads all have an adverse effect on
fuel consumption.
Erratic driving habits
Anticipate hazards ahead and keep
a safe distance from the vehicle in
front.
This not only reduces fuel
consumption but also the noise
level.
If you have a prolonged wait at
a railway crossing or at traffic
lights in built-up areas, it is
advisable to switch off the engine
during this period.
Waiting three minutes with the
engine running equates to almost
1 km of driving.
Vehicle load conditions
Increased vehicle load will result in
higher fuel consumption. Remove
roof racks when not in use.
Vehicle condition
Low tyre pressure or inadequate
maintenance of the engine or
vehicle will also result in higher fuel
consumption.
