Technical Data
FuelPetrolGrades of petrolThere are various grades of petrol. Please read in order to know which grade of
petrol your vehicle requires. You will also find the same information affixed to the
inside of the fuel filler flap of your vehicle ⇒page 158.
A distinction is made between unleaded an d leaded petrol. All Škoda vehicles with
petrol engines are equipped with a catalyti c converter and must therefore be only
driven with unleaded petrol . Unleaded petrol complies with the standard
DINEN228 .
The individual grades of petr ol are distinguished by their octane number (RON).
Please adopt the following procedure if the grade of petrol which you normally use
is not be available in exceptional circumstances:•
Engines which need unleaded premium petrol 95 RON can also be run on
unleaded regular petrol 91 RON. This does, however, result in a slight loss in
performance.
•
Engines which need unleaded premium plus petrol 98 RON can also be run
on unleaded regular petrol 95 RON. This does, however, result in a slight loss in
performance. You can in exceptional circumstances also use unleaded regular
petrol of 91 RON in the event that neithe r unleaded premium petrol of 98 RON nor
95 RON is available. Refuel as soon as possible with unleaded premium plus of 98
RON or unleaded premium petrol of 95 RON.
If, in an emergency, the only fuel availa ble is one which has a lower octane number
than that required by the engine then only drive at medium engine speeds and
lower engine loadings.
You can make unlimited use of fuel whic h has a higher octane number than that
required by the engine. There will, howeve r, be no advantages gained by this in
terms of engine performance and fuel consumption! The handling, performance and life of your engine are determined to a significant
extent by the quality of the fuel.
Do not use any petrol additives. Use a fuel
complying with the standard.
You can find further information on refuelling ⇒page 158, “Refuelling”.
Caution
•
Filling the tank even only once with lead ed petrol will result in the catalytic
converter being destroyed.
•
Operating the engine with petrol of a lo w octane number can result in engine
damage at high revolutions or severe engine loading.
DieselDiesel fuelYour vehicle can be operated with diesel fuel, which complies with the standard
DIN EN 590 .
Fuel additives
You must not use fuel additives, so-called “flow improvers” (petrol and similar
products) in diesel fuel.
If the quality of the diesel fuel is poor, it is then necessary to drain the fuel filter
more often than stated in the Service schedule.
You can find information on refuelling ⇒page 158, “Refuelling”.
Caution
•
Use fuel which complies with the standard DIN EN 590. Filling the tank even
only once, which does not comply with th e standard, can result in damage to the
fuel system.
•
Water which has collected in the fuel fi lter can result in engine problems.

Fuel
158•
Your vehicle is not adapted for use of biof uel (RME), therefore this fuel must not
be refuelled and driven. Using this fuel (R ME) can lead to damage to the engine or
the fuel system.
Operation in winterWinter-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 result
in operational problems because the diesel becomes viscous as a result of paraffin
separation.
It is therefore the case that DIN EN 590 prescribes diesel fuel class for certain
periods of the year which can also be pu rchased 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 diff erent climatic conditions that diesel fuels
available have a different temperature characteristic. The specialist garages and
filling stations in the country concerned wi ll be able to provide you with informa-
tion regarding the diesel fuels available.
Prewarming fuel
The vehicle is fitted with a fuel filter prewarming 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 petrol,
to diesel fuel in order to improve its flow properties.
RefuellingThe filler tube of the fuel reservoir is located in the rear right side part of
the vehicle.
Opening the fuel filler cap
– Open the fuel filler flap with the hand.
– On vehicles without remote unlocking of the fuel filler flap from the
driver's seat, unlock the fuel filler cap on the fuel filler tube by turning
the vehicle key to the left.
