Correct driving techniques will considerably affect fuel con-
sumption. There will also be less wear on the bus and the
passengers will have a more comfortable ride.
Only a fraction of the engine output is required when the bus
is moving at an even speed. The engine will use a minimum
of fuel. When the accelerator is depressed and the bus starts
to accelerate, a greater portion of the engine output is uti-
lized. Fuel consumption will increase considerably.
It may be necessary to brake just afterwards, which will make
it an expensive increase in speed. Advanced planning and
constant speed gives high passenger comfort and best
economy.
Treat the accelerator pedal with care and change gear at the
correct engine speed. Buses with automatic transmission:
keep a light foot on the accelerator and allow the gearbox to
shift at low engine speeds. Avoid using kick-down.
The engine speed range that gives the best fuel economy is
marked in green on the tachometer.
Do not change down until the engine speed has dropped to
the bottom of the green zone when driving uphill.
Accept a certain drop in speed when driving uphill. Ease up
on the accelerator before the crown of a hill and do not de-
press it if it is downhill on the other side.
High speed will always mean increased fuel consumption. Re-
member: Twice the speed will quadruple air resistance.
Use good roads. If it is possible to choose your route: avoid
bad roads with hills and many stops.
Radial tyres have low rolling resistance, but check the air
pressure regularly. Sufficient pressure makes the tyres roll
easier and reduces wear.

Avoid unnecessary and
rapid acceleration.
Avoid jerky driving.
Constant road speed and
correct engine speed give
the lowest consumption.
