Dr ive in an energy a nd environment-
consc ious w ay
zHigh fuel consumption, noise lev els and
exhaust em issions are often caused by a
driving s tyle that is not energy and
environment-conscious.
zYou should therefore drive with energy in
mind: "more kilometre s/ miles with le ss
fuel".
Reduce the noise level and exhaust
emissions b y adopting an environment-
consc ious driving s tyle. This is ex treme ly
worthwhile and im proves the quality of
life.
Fuel consum ption d epend s to a great
extent on your own personal d riv ing
style. The following hints are intended to
help you consume fuel at a rate that is as
clos e as poss ible to the spe cified le vels –

causing increased fuel consumption. Warm ing up
zFull throttle and w arming up at idle
speed increase w ear, fuel consumption,
ex haust em issions, the amount of
pollutant in the exhaust and the am ount

zDriv e off as s oon as poss ible a fte r

Uniform speed
zHectic driving s ignificantly increas e s fuel
consumption, the ex haust emissions, the
proportion of pollutant in the exhaust
g a s es a n d t h e no i s e l eve l .
zDo not accele rate a nd brake
unnecessarily . Drive at uniform speed.
Avoid frequent starting-off and
stopping, e.g. at traffic lights, in short
distance traffic and in que ue s of tra ffic,
by m eans of clev er planning. S ele ct
roa ds with good traffic flow.
I dling
zThe eng ine also consumes fuel when
idling .
zIf yo u h ave to wait f o r mo r e th an

zSlightly relea sing the acce le rator ped al
res ults in distinct fuel s avings with no

Drive at no more tha n around thre e

zSw itch off ad ditional c ons umers (e. g.

when they are no longer required. Re pai r and m ainte nance
zImprope r repairs or adjus tm ent and
maintenance work can increase fuel
consumption. Do not carry out w ork on
the eng ine yourself.
You ma y infring e environmental la ws out
of ignorance by not d isposing of
materials prope rly.
Appropriate parts might not b e re cycle d.

F or the first few thousa nd kilome tres/m ile s,

This increases fuel consump tion.
Fuel for petrol engines
Normal comme rc ia l hig h-q uality fue ls
with a m aximum ethanol conte nt of 5% in
accordance with DIN EN 22 8 are suitable
(Cataly tic converte r - s ee page 1 16 .
O ctane numbe rs - se e page 17 5 ). The
quality thereof has considerable effect on
performance, running and service life of
the e ngine. The additive s mixe d with the
fuel are extremely im portant. For this
r ea so n yo u mu s t o n ly r e fu e l with h igh-
quality fuels containing additives.Fuels with e thanol content of gre ater than
5% d o not com ply with DIN EN 228 and
must not be used unless the v ehicle has
bee n s pe cifica lly dev eloped a nd ap prov ed
for these fuels.
Fuel with too low an octane number can
cause pinking. Opel cannot b e held liable
for re sulting dam age.
Petrol with a higher octane number can
always be use d.
