„Diesel fuel mixture according to standard CSN 65 6508 from
02/2003 contains diesel fuel according to standard DIN EN 590 and a
concentration of biofuel (rape oil methyl ester) according to standard
DINEN14214 in the following two concentrations:
„5% share of biofuel RME according to the standard DINEN14214
- Denomination SMN 5,
„30% share of biofuel RME according to the standard
DINEN14214 - Denomination SMN 30.
Fuel additives
You must not use fuel additives, so-called “flow improvers” (petrol and
similar products) in diesel fuel.
It is then necessary to have the fuel filter drained of water by a Škoda
dealer more often than stated in the Service schedule if the quality of the
diesel fuel used is poor.
You can find information on refuelling ⇒page 188, “Refuelling”.
Caution
•Use a fuel complying with the standard. Filling the tank even only once,
which does not comply with the standard, can result in damage to the fuel
system.
•Water which has collected in the fuel filter can result in engine
problems.
Biofuel*
Biofuel (methyl ester from rape oil) is manufactured from vegetable oil by
means of a chemical process.
Biofuel does not contain sulphur. This means that no sulphur dioxide
(SO
2) is produced when it is burnt. The exhaust gases contain less
•carbon monoxide (CO),
•hydrocarbons (HC),
•particles (soot)
than when operating with conventional diesel fuel.
The Biofuel is more biodegradable.
When using biofuel pay attention to the following points:
•The Performance may be reduced slightly if you switch to driving with
biofuel.
•The fuel consumption may increase slightly if you switch to driving
with biofuel.
Biofuel conforming to EN 14 214 can be mixed in any desired ratio with
diesel fuel conforming to the standard DIN EN 590.
We recommend refuelling with diesel fuel at temperatures below -10°C.
Caution
•Filling the tank even only once with biofuel, which does not comply with
the standard EN 14 214, can result in damage to the fuel system.
•It is prohibited to use biofuel for engine 1.4 l/59 kW TDI PD EU4 which
corresponds to the standard DINEN14 214.
Operation in winter
Winter-grade diesel fuel
A different grade of diesel fuel is available at filling stations in winter than
during the summer. Using “summer-grade diesel fuel” at temperatures

below 0°C can result in operational problems because the diesel becomes
viscous as a result of paraffin separation.
It is therefore the case that DIN EN 590 prescribes diesel fuel class for
certain periods of the year which can also be purchased at the corre-
sponding time during the year. “Winter-grade diesel fuel” will still operate
properly even at a temperature of -20°C.
It is often the case in countries with different climatic conditions that diesel
fuels available have a different temperature characteristic. Škoda dealers
and filling stations in the country concerned will be able to provide you with
information regarding the diesel fuels available.
Prewarming fuel
The vehicle is fitted with a fuel filter prewarming system. This secures
operation of a vehicle using diesel fuel down to an environmental temper-
ature of -25°C.
Biofuel
We recommend refuelling with diesel fuel at temperatures below -10°C.
Caution
It is not permitted to add the various fuel additives on the market, including
petrol, to diesel fuel in order to improve its flow properties.
