Diesel; Refuelling - Skoda Octavia Owner's Manual

178 Fuel
For the sake of the environment
The use of engine preheating at temperatures below -10 °C has a positive effect
on the fuel consumption and thus on the environment.
Note
An extension cable used for connecting to the electrical network is located in the
luggage compartment.

Diesel

Diesel fuel
Your vehicle can only be operated with diesel fuel, which complies with the stand-
ard EN 590 (standard DIN 51628 in Germany, standard ÖNORM C 1590 in Austria,
GOST R 52368-2005/EN 590:2004 in Russia).
Fuel additives
You must not use fuel additives, so-called "flow improvers" (petrol and similar
products) in diesel fuel.
You can find information on refuelling ⇒ p age 178, Refuelling.
CAUTION
● Your vehicle can only be operated with diesel fuel, which complies with the
standard EN 590 (standard DIN 51628 in Germany, standard ÖNORM C 1590 in
Austria, GOST R 52368-2005/EN 590:2004 in Russia). Filling the tank even only
once with diesel fuel which does not comply with the standard, can result in dam-
age to the engine parts, the lubrication system, the fuel and exhaust system.
● If by mistake you have refuelled with a different fuel other than the diesel fuel
which complies to the above mentioned standards (e. g. petrol), do not start the
engine or switch on the ignition! Severe damage damage is possible! Contact a
specialist garage and have the fuel system of the engine cleaned.
● Water which has collected in the fuel filter can result in engine problems.
● Your vehicle is not adapted for use of biofuel (RME), therefore this fuel must
not be refuelled and driven. The use of biofuel (RME) can lead to damage to the
engine or the fuel system.
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 re-
sult in operational problems because the diesel becomes viscous as a result of
paraffin separation.

It is therefore the case that the standard EN 590 (standard DIN 51628 in Germany,
standard ÖNORM C 1590 in Austria, GOST R 52368-2005/EN 590:2004 in Russia)
is the diesel fuel class prescribed for certain periods of the year which can also be
purchased at the corresponding 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. The authorised ŠKODA Serv-
ice Partners and filling stations in the country concerned will be able to provide
you with information regarding the diesel fuels available.
Preheating fuel
The vehicle is fitted with a fuel filter preheating system. This secures operation of
a vehicle using diesel fuel down to an environmental temperature of -25 °C.
CAUTION
It is not permitted to add the various fuel additives on the market, including pet-
rol, to diesel fuel in order to improve its flow properties.
