Urban Traffic; High Speed; Electrical Loads - Vauxhall Omega Owner's Manual

Urban traffic

z Freq uent sta rting a nd stopping – for
exam ple a t traffic lig hts, in stop-start
traffic or traffic queues – greatly
increases average fuel consumption.
z Plan carefully to avoid traffic c ongestion.
Good anticip ation a voids unnec essary
stopping.
If possible, selec t roa ds with a good
traffic flow.
By keeping a safe distance from the
vehicle in front a nd by not la ne-hopping
you will be able to avoid frequent
braking and acceleration, whic h uses up
a lot of fuel.

High speed

z The higher the speed , the higher the
consumption. At top speed, you
consume a great dea l of fuel.
z Slightly releasing the accelerator pedal
results in distinct fuel sa ving s w ith no
major loss of speed.
Driv e at no m ore than around three
qua rters of m aximum speed and y ou will
use up to 50 % less fuel, w ithout losing a
great deal of time.
Tyre inflation pres sure
z Inadequate ty re p ressure, leading to
higher road resistance, costs m oney in
two wa ys: for more fuel and increased
tyre wear.
z Regular checks (every 14 d ays) pay off.

Electrical loads

z The power consum ption of electrical
equip ment increa ses fuel consumption.
z Sw itch off all aux iliary electrical loads
(e. g. heated rear window, heated
seats 3 ) when not needed.
Automatic trans miss ion
z Full throttle, kickdown, the sporty d riv ing
programm e and unnec essary manual
changing of drive ranges all severely
increase fuel consump tion.
z Driving can a lmost a lw ays be
maintained in D. If the accelerator pedal
is depressed gently and evenly the
transm ission will shift into the fuel-sa ving
gears at an early stage.
Loading
z Unnecessary weight increa ses fuel
consump tion, especially when
accelerating (urban traffic). A load of
100 kg can increase fuel consum ption in
urban traffic by up to
1.75 gal./1000 m iles; (0. 5 l/100 km ).
z Reduce the loads you carry.
Roof racks, s ki-holders
z Roof ra cks and ski-holders can increase
fuel consumption by approx.
3. 5 g al./1000 miles (1 l/100 km) ; due to
the increased air resistanc e.
z Remov e them if they are not being used .
Repair and maintenance
z Improper repairs or adjustm ent and
maintenance work can increase fuel
consumption. Do not carry out w ork on
the eng ine yourself.
z We recom mend that repair and
maintenance be entrusted to your
Vauxhall Authorised Repairer.
Extre me driving conditions
z Driv ing up steep gradients, driv ing on
poor roa ds, cornering, pulling a
caravan/tra iler or winter d riv ing all
increase fuel consumption.
Fuel consumption increa ses dramatically
in urba n tra ffic a nd at winter
temperatures, especially on short trip s
when the engine operating tempera ture
is not reached.
z Follow the hints given above to keep
consumption to a m inimum under suc h
cond itions.
