Unleaded petrol
Read and observe
and on page 183 first.
The vehicle can only be operated with unleaded petrol that meets the EN 2281)
standard.
All petrol engines can be operated using petrol with a maximum of 10% bioe-
thanol (E10).
Specified fuel - unleaded petrol 95/91 or 92 or 93 RON
Use unleaded fuel with an octane rating of 95 RON. Unleaded petrol with the
octane ratings 91 or 92 or 93 RON can also be used, but may result in a slight
loss in performance and slightly increased fuel consumption .
Prescribed fuel - unleaded petrol min. 95 RON
Use unleaded fuel with an octane rating of 95 RON or higher.
If unleaded gasoline is not available with the octane number 95 RON, in an
emergency petrol with the octane rating of 91 or 92 or 93 RON can be used to
fill the tank, but this leads to a slight loss of performance and a slightly in-
creased fuel consumption »
.
Prescribed fuel - unleaded fuel 98/95 RON
Use unleaded fuel with an octane rating of 98 RON or higher. Unleaded petrol
95 RON can also be used but results in a slight loss in performance.
In an emergency, if unleaded petrol with an octane rating of 98 RON or 95 RON
is not available, you may refuel with petrol with an octane rating of 91 or 92 or
93 RON »
.
Fuel additives
Unleaded petrol complying with EN 228 1 )
meets all the conditions for a smooth
running engine. We therefore recommend that no fuel additives are used. This
can result in considerable damage to parts of the engine or the exhaust sys-
tem. 
1)
In Germany also DIN 51626-1 or E10 for unleaded petrol with octane rating 95 or 91 or DIN 51626-2 or E5
for unleaded petrol with octane rating 95 or 98.
184General Maintenance

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 used by mistake, do not start the engine or
switch on the ignition! Engine parts could be significantly damaged!
CAUTION
■ If, in an emergency, the vehicle has to be refuelled with petrol of a lower oc-
tane number than the one prescribed, the journey must only be continued at
medium engine speeds and a low engine load. Driving at high engine revs or a
high engine load can severely damage the engine! Refuel using petrol of the
prescribed octane number as soon as possible.■
Engine parts can be damaged if petrol with a lower octane number than the
one prescribed is used.
■
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 and iron content. There is a risk of causing considerable
damage to parts of the engine or exhaust system!
CAUTION
Fuels with metal components, such as LRP (lead replacement petrol) must
not be used. There is a risk of causing considerable damage to parts of the
engine or exhaust system!
Note
■ 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 95/91, 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
Read and observe
and on page 183 first.
The vehicle can only be operated with diesel fuel that meets the EN 5901)
standard.
All diesel engines can be operated using diesel fuel with a maximum of 7% bi-
odiesel (B7)2)
.
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. ŠKODA Partners
and filling stations in the relevant country will be able to provide you with in-
formation regarding the diesel fuels available.
Preheating fuel
The vehicle is fitted with a fuel filter preheating system. This secures opera-
tion of a vehicle using diesel fuel down to an environmental temperature of
-25 °C.
Diesel fuel additives
The diesel fuel in accordance with the prescribed standards meets all the con-
ditions for a smooth running engine. We therefore recommend that no diesel
fuel additives are used. This can result in considerable damage to parts of the
engine or the exhaust system. 
1)
In Germany also DIN 51628, in Austria ÖNORM C 1590, in Russia GOST R 52368-2005 / EN 590:2004.
2)
In Germany complying with standard DIN 52638, in Austria ÖNORM C 1590, in France EN 590.
185Inspecting and replenishing

CAUTION■Just filling the tank once with diesel fuel that does not comply with the
standard, can cause severe damage to parts of the engine, the fuel and ex-
haust system!■
If a different fuel other than diesel fuel, which complies to the above men-
tioned standards (e.g. petrol) is used, do not start the engine or switch on the
ignition! Engine parts could be significantly damaged!
■
Water which has collected in the fuel filter can cause engine faults.
CAUTION
■ The vehicle cannot be operated with biofuel RME, therefore this fuel must
not be filled in the tank and used for driving the vehicle. The use of biofuel
RME can cause considerable damage to parts of the engine or fuel system.■
Do not mix any fuel additives, so-called “flow improvers” (petrol and similar
agents), into the diesel. This can result in considerable damage to parts of the
engine or the exhaust system!
