Unleaded petrol
First read and observe the introductory information and safety warn-
ings
on page 157.
Your vehicle can only be operated with unleaded petrol complying with EN 2281)
.
All petrol engines can be operated using petrol with a maximum of 10% bioetha-
nol (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 oc-
tane ratings 91, 92 or 93 RON can also be used, but may result in a slight loss in
performance.
Prescribed fuel - unleaded petrol min. 95 RON
Use unleaded fuel with an octane rating of 95 RON or higher.
In an emergency, if unleaded petrol with an octane rating of 95 RON is not availa-
ble, you may refuel with petrol with an octane rating of 91, 92 or 93 RON »
.
Prescribed fuel - unleaded petrol 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 system.
CAUTION■ Even filling the tank with leaded petrol that does not meet the standard once
can lead to serious damage to parts of the exhaust system.■
Do not start the engine or switch on the engine if you have refuelled in error
with a fuel other than unleaded fuel which complies to the standards referred to
above (e.g. leaded petrol). Engine parts could be significantly damaged. We rec-
ommend that you have the fuel system cleaned by a specialist garage.
CAUTION
■ If, in an emergency, the vehicle has to be refuelled with petrol of a lower octane
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 oc-
tane number as soon as possible.■
Engine parts can be damaged if petrol with a lower octane number than the one
prescribed is used.
■
Petrol of an octane rating lower than 91 RON must not be used, even in the
event of an emergency, otherwise the engine could be severely damaged.
CAUTION
■ In no case may fuel additives with metal components be used, especially not
with manganese and iron content. LRP(lead replacement petrol) fuels with metal-
lic constituents may not be used. There is a risk of causing considerable damage
to parts of the engine or exhaust system.■
Fuels with metallic constituents may not be used. There is a risk of causing con-
siderable damage to parts of the engine or exhaust system. 
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.
158General Maintenance

Note■Unleaded petrol that has a higher octane number than that required by the en-
gine can be used without limitations.■
The use of petrol with an octane rating higher than 95 RON in does not result in
either a noticeable increase in power nor lower fuel consumption in vehicles 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 petrol
with a higher octane number than 95 RON can increase the power and reduce
fuel consumption.

Diesel fuel
First read and observe the introductory information and safety warn-ings
on page 157.
Your vehicle can only be operated with diesel fuel that meets the EN 5901)
stand-
ard.
All diesel engines can be operated using diesel fuel with a maximum of 7% bio-
diesel (B7)2)
.
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 fuelsavailable have a different temperature characteristic. ŠKODA Partners and filling
stations in the relevant country will be able to provide you with information re-
garding the diesel fuels available.
Diesel fuel additives
Additives, so-called “flow improvers ” (petrol and similar agents) should not be mixed with the diesel fuel. This can cause serious damage to engine or exhaust
system parts.
CAUTION■ Just filling the tank once with diesel fuel that does not comply with the stand-
ard, can cause severe damage to parts of the engine, the fuel and exhaust sys-
tem!■
If a different fuel other than diesel fuel, which complies to the above mentioned
standards (e.g. petrol) is used by mistake do not start the engine or switch on the
ignition! Extensive damage to engine parts can occur! We recommend that you
have the fuel system cleaned by a specialist garage.
■
Water which has collected in the fuel filter can cause engine faults.
CAUTION
■ Your vehicle cannot be operated with RME biofuel; you must therefore not fill
your vehicle or attempt to drive it with this fuel. The use of biofuel RME can cause
considerable damage to parts of the engine or fuel system.■
Additives, so-called “flow improvers” (petrol and similar agents) should not be
mixed with the diesel fuel. This can cause serious damage to engine or exhaust system parts.
