FuelPetrol enginesUnleaded petrol conforming to DIN EN
228 RON 91, 95 and 98
1)
Notes
Use only high-quality fuel.
Unleaded petrol RON 91 (95)
1) 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!
1) This applies to Octavia RS and Octavia Estate
RS
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.
Biodiesel
We recommend refueling with diesel fuel
at temperatures below -10 °C.

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.
Biodiesel (PME1 fuel) conforming to
DIN EN 14 214
1)
Cetane number at least 49
Vehicles with diesel engines can also be
operated with biodiesel. The term biodiesel
specifies methyl ester from rape oil, which
must comply with the requirements of the
standard DIN EN 14 214
1).
Warning
Filling the tank even only once with
biodiesel, which deviates from the
standard DIN EN 14 2141), can lead to
damage in the fuel system. Particular features of PME fuel
Biodiesel is manufactured from vegetable
oil using a chemical process.
Biodiesel is sulphur-free which is why no
sulphur dioxide (SO
2) is released when it
is combusted.
The exhaust gas contains less
- carbon monoxide (CO)
- hydrocarbons (HC)
- particulates (e.g. soot)
than when the engine is operated with a
conventional diesel fuel.
If biodiesel is used, the vehicle performance
may be slightly lower and, on the other hand,
fuel consumption may be slightly higher.
Biodiesel is biologically degradable.
PME fuel according to DIN EN 14 214
1) can
be mixed in any desired ratio with diesel
fuel conforming to DIN EN 590.
Driving in winter
PME fuel is suitable for use in winter only
down to -10 °C.
Fuel additives (flow improvers) and simi-
lar products must not be added to the
biodiesel fuel.
