FuelPetrol enginesUnleaded petrol conforming to DIN EN
228 RON 95
Notes

Use only high-quality fuel.

Unleaded petrol RON 95 can be
used although engine output in this case is
slightly reduced.

Fuels with a higher octane number than
specified can be used without restrictions.
This does not offer any advantages in re-
spect of engine output and fuel con-
sumption, however!
Cars with a catalytic converter must only be driven with unleaded fuel.
Using fuels which contain lead results in a
lead deposit forming in the catalytic con-
verter.
Even refuelling only once with lea-
ded petrol destroys the effect of the
catalytic converter.
Even if the fuel tank is then again filled with
unleaded fuel, the original efficiency of the
catalytic converter is no longer achieved.
The operation, power output and dura-
bility of the engine are affected to a ma-
jor extent by the quality of the fuel. Do
not mix any additives into the fuel. Use
only fuel which complies with official
standards.
Diesel enginesDiesel fuel complying with DIN EN 590.
Cetane number not less than 49.
Driving in winter
Winter-grade diesel fuel
In winter a different grade of diesel fuel is
available at filling stations than during the
summer months. If „summer-grade diesel
fuel“ is used, operational problems may
occur at temperatures below 0 °C because
the diesel becomes too viscous as a result
of paraffin separation. „Winter-grade die-
sel fuel“, in contrast, is still fully operational
down to -20 °C.
In countries with different climatic condi-
tions, it is quite common to find diesel fu-
els which have a different temperature
characteristic. Škoda Dealers, and filling
stations in the particular country, will pro-
vide you with further information regarding
the diesel fuels which are available in that
country.

GENERAL MAINTENANCE
Care of carRegular, professional care is a way of re-
taining the value of your car.
In addition, it may also be one of the re-
quirements for a warranty claim in the event
of possible corrosion damage and paint
defects on the body.
The care products required are available
as Original Accessories from Škoda. Al-
ways follow the instructions for use stated
on the packaging.Warning

If misused, car care products can
be harmful to health.

Car care products should always
be stored in a safe place where they
are out of the reach of children.
When buying car care products, al-
ways select products which have
been designed to minimize pollution of the environment. Do not dispose of carcare products in domestic refuse.
Fuel filter preheater
The car is equipped with a fuel filter pre-
heater. This ensures proper operation of the
fuel system down to about -25 °C when
using winter-grade diesel fuel which is re-
sistant to temperatures down to -15 °C.
Should the engine no longer start at tempe-
ratures below -25 °C, it is sufficient to park
the car for a certain time in a heated area.
Fuel additives (flow improvers) and simi-
lar products must not be added to the
diesel fuel.
Use only fuel, which complies with offi-
cial standards. Even refueling only once
with fuel which does not comply with of-
ficial standards can lead to damage in
the fuel system.
