Unleaded petrol that has a higher octane number than that required by the en-
■
gine can be used without limitations.
On vehicles with prescribed unleaded petrol 95/91, 92 or 93 RON, the use of
■
petrol with a higher octane number than 95 RON does not result in a noticeable
power increase or a lower fuel consumption.
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 204.
Your vehicle can only be operated with diesel fuel that meets the EN 590
ard.
All diesel engines can be operated using diesel fuel with at most 7% biodiesel
(B7) .
2)
For the Indian market, your vehicle can run only on diesel fuel compliant 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 information re-
garding 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.
1) In Germany also DIN 51628, in Austria ÖNORM C 1590, in Russia GOST R 52368-2005 / EN 590:2004.

General Maintenance
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.
