2009 SKODA SUPERB maintenance schedule

Driving and the Environment
204
Avoiding full throttle Driving more slowly means saving fuel.Sensitive use of the accelera
tor will not only significantly reduce fuel consumption
but also positively influence environmen
tal pollution and wear of your vehicle.
You should avoid fully exploi
ting the top speed of your vehicle wherever possible.
Fuel consumption, pollutant emissions and vehicle noises increase disproportion- ally at high speeds. The
⇒fig. 195
shows the ratio of fuel consumption to the speed of your vehicle.
You will cut your fuel consumption by half
if you only make use three-quarters of
the possible top speed of your vehicle.Reducing idling Idling also costs fuel.It is worthwhile switching off the engine in
a traffic jam or when waiting at a level
crossing or at traffic lights with a length
y red phase. Even after just 30 - 40 seconds
you will have saved more fuel than that
is needed when you start the engine up
again. If an engine is only idling it takes much
longer for it to reach its normal operating
temperature. Wear-and-tear and pollutant em
issions, though, are particularly high
in the warming-up phase. This is why you
should drive off right after starting the
engine. Do avoid high engine re
volutions at this time, however.
Regular servicing A poorly tuned engine consumes an unnecessarily high amount of fuel.Having your vehicle serviced regularly at a specialist garge enables you to satisfy one
of the requirements for economical moto
ring even before you set off on your
journey. Keeping your vehicle properly servic
ed not only has a positive effect on the
safety of your vehicle and maintaining its value, but also saves on
fuel
.
A poorly tuned engine can result in a fu
el consumption which is 10% higher than
normal. The foreseen maintenance work should be undertaken exactly according to the Service schedule by a specialist garage. Also check the
oil level
after refueling.
Oil consumption
is dependent to a consid-
erable extent on the load and speed of
the engine. Oil consum
ption could be as
high as 0.5 litres/1 000 km depending on your style of driving. It is quite normal that a new engine ha
s a higher oil consumption at first, and
reaches its lowest level only
after a certain running in
time. It is therefore not
possible to correctly assess the oil cons
umption of a new vehicle until after you
have driven about 5 000 km.
For the sake of the environment
•
You can achieve additional improvements
in your fuel economy by using high-
lubricity oils.•
Check the ground below your car at regula
r intervals to detect any leakages in
good time. Please have your
vehicle inspected by a specialist garge if you find any
stains caused by oil or
other fluids on the floor.

Technical Data
FuelPetrolGrades of petrolThere are various grades of petrol. Please read
⇒page 267, “Technical Data” in
order to know which grade of petrol your
vehicle requires. You will also find the
same information affixed to the inside of
the fuel filler flap of your vehicle
⇒ page 220, fig. 199
.
A distinction is made between unleaded an
d leaded petrol. All Škoda vehicles with
petrol engines are equipped with a catalyti
c converter and must therefore be only
driven with
unleaded petrol
. Unleaded petrol
complies with the
standard
DINEN228
.
The individual grades of petr
ol are distinguished by their
octane number
(RON).
Please adopt the following procedure if the grade of petrol which you normally use is not be available in
exceptional circumstances.
•
Engines which need
unleaded premium petrol 95 RON
can also be run on
unleaded regular petrol 91 RON. This does, however, result in a slight loss in performance. If, in an emergency, the only fuel availa
ble is one which has a lower octane number
than that required by the engine then only drive at medium engine speeds and lower engine loadings. You can make unlimited use of fuel whic
h has a higher octane
number than that
required by the engine. There will, howeve
r, be no advantages gained by this in
terms of engine performance and fuel consumption! The handling, performance and
life of your engine are determined to a significant
extent by the quality of the fuel.
Do not use any petrol additives.
Use a fuel
complying with
the standard.
You can find further information on refuelling
⇒page 220, “Refuelling”.
Caution
•
Filling the tank even only once with lead
ed petrol will result in the catalytic
converter being destroyed.•
Operating the engine with petrol of a lo
w octane number can result in engine
damage at high revolutions or severe engine loading.DieselDiesel fuelYour vehicle can be operated with
diesel fuel
, which complies with the standard
DIN EN 590
.
Fuel additives You must not use fuel additives, so-called “flow improvers” (petrol and similar products) in diesel fuel. If the quality of the diesel fuel is poor, it is then necessary to drain the
fuel filter

more often than stated in the Service schedule. You can find information on refuelling
⇒page 220, “Refuelling”.
Caution
•
Use fuel which complies with the standard
DIN EN 590
. Filling the tank even
only once, which does not comply with th
e standard, can result
in damage to the
fuel system.•
Water which has collected in the fuel fi
lter can result in engine problems.
•
Your vehicle is not adapted
for use of biofuel (RME), therefore this fuel must not
be refuelled and driven. Using this fuel (RME) can lead to damage to the engine or the fuel system.

Inspecting and replenishing
226
Changing engine oilThe engine oil must be changed at the intervals stated in the Service schedule or according to the service interval indicator
⇒page 20, “Service Interval Display”.
WARNING
•
Only carry out the engine oil change, if you have the required profes-
sional knowledge!•
Read and observe the warning notes
⇒page 223, “Working in the engine
compartment” before working in the engine compartment.•
Let the engine cool down - risk of burning from hot oil.
•
Wear an eye protection - risk of
caustic burns due to oil splashes.
•
Oil is toxic! Store old oil in a safe place out of the reach of children and
unauthorized persons until you dispose of it properly.
Caution
You must not pour any additives into th
e engine oil - risk of engine damage!
Damage, which results from such product, are excluded from the warranty.
For the sake of the environment
•
You must on no account pour oil into the ground or into the sewage system.
•
In view of the problems involved in prop
erly disposing of old oil, the necessary
special tools and the knowledge required for such work, we recommend that you have the oil and oil filter change carried
out by an authorised Škoda Service Partner.
Note
After your skin has come in contact with
the oil, you must thoroughly wash your
skin.
Cooling systemCoolant The job of the coolant is to cool the engine.The cooling system does not require an
y maintenance under normal operating
conditions. The coolant consis
ts of water with a concentration of coolant additive
of 40 %. This mixture not only provides
antifreeze protection down to -25°C but
also protects the cooling and heating system
from corrosion. It also prevents the
formation of scale and significantly increases the boiling point of the coolant. You must therefore not reduce the concentration of antifreeze agent in the coolant by adding water, also not
during the summer months or in countries with a warm
climate.
The concentration of coolant additive in the coolant must be at least
40%. You can increase the amount of antifreeze
in the coolant if a higher concentration
of antifreeze is necessary for climatic
reasons but only up to 60% (antifreeze
protection down to approx. -40°C). The an
tifreeze protection tails off above that
concentration. Vehicles exported to countri
es with a cold climate (e.g. Sweden, Norway, Finland)
are already factory-filled with a coolant which offers antifreeze protection down to about -35°C. In these countries the concentr
ation of coolant additive should be at
least 50 %. Coolant The cooling system is factory-filled with c
oolant (purple in colour), which complies
with the specification TL-VW 774 G. We recommend that you use the same co
olant additive - G12 PLUS-PLUS (purple
in colour) for topping up the system. Please contact an authorised Škoda Service Partner if you have any questions regarding the coolant or if you wish
to fill up with a different coolant.
An authorised Škoda Service Partner can
also supply you with the correct coolant
additives.
