Fuel additives
Unleaded petrol in accordance with the EN 228 standard
tions for a smooth-running engine. We therefore recommend that no fuel ad-
ditives are used. This can result in considerable damage to parts of the engine
or the exhaust system.
CAUTION
Even one filling of the tank with petrol that does not meet the standards can
■
lead to serious damage to parts of the exhaust system!
If a fuel other than unleaded fuel which complies to the above mentioned
■
standards (e.g. leaded petrol) is put in the tank by mistake, do not start the en-
gine or switch on the ignition. Extensive damage to engine parts can occur.
CAUTION
If petrol with a lower octane number than the one prescribed is used do not
■
drive with a high engine speed. A high engine load can severely damage en-
gine components.
Even in the event of an emergency, petrol of a lower octane number than 91
■
RON must not be used, otherwise the engine can be severely damaged.
CAUTION
In no case may fuel additives with metal components be used, especially not
with manganese or iron content. There is a risk of causing severe damage to
parts of the engine or exhaust system.
CAUTION
Do not use fuels with metal components, such as LRP (lead replacement
petrol). There is a risk of causing severe damage to parts of the engine or ex-
haust system.
1)
In Germany also DIN 51626-1 or E10 for unleaded petrol with octane number 91 or 95 or DIN 51626-2 or E5
for unleaded petrol with octane number 95 and 98.
2)
In Germany also DIN 51628, in Austria ÖNORM C 1590, in Russia GOST R 52368-2005 / EN 590:2004.
3)
In Germany according to the DIN 52638 standard, in Austria ÖNORM C 1590, in France EN 590.
Note
meets all the condi-
1)
Unleaded petrol that has a higher octane number than that required by the
■
engine can be used without limitations.
The use of petrol with an octane rating higher than 95 RON in does not re-
■
sult in either a noticeable increase in power nor lower fuel consumption in ve-
hicles for which unleaded petrol 95/min 92 or 93 RON is specified.
On vehicles using prescribed unleaded petrol of min. 95 RON, the use of pet-
■
rol with a higher octane number than 95 RON can increase the power and re-
duce fuel consumption.
Diesel fuel
The correct fuel grades for your vehicle are specified on the inside of the fuel
filler flap.

Read and observe
The vehicle can only be operated with diesel fuel that meets the EN 590
standard.
All diesel engines can be operated using diesel fuel with at most 7% biodiesel
(B7) .
3)
On the Indian market, your vehicle will only be able to run on diesel fuel com-
pliant with standard IS 1460/Bharat IV. If diesel fuel which complies with this
standard is not available, you can refuel with diesel fuel according to standard
IS 1460/Bharat III in case of emergency.
Operation in winter – Winter-grade diesel fuel
In the cold season, only use "winter-grade diesel fuel" which 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 ŠKODA Part-
ners and filling stations in the relevant country will be able to provide you with
information regarding the diesel fuels available.
