Technical Data
FuelPetrolGrades of petrolThere are various grades of petrol. Please read
⇒page 271, “Technical Data” 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 222, fig. 206
.
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. 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 222, “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.Biofuel Ethanol E85*Ethanol E85* Only valid for vehicles with
1.6/75°kW MultiFuel engine.
Biofuel Ethanol E85 consists of 85% bioethanol and 15% unleaded petrol complying with the standard (DIN) EN°228. Biofuel Ethanol E85 in accordance with th
e standard (DIN) EN 2
28 can be mixed in
any desired ratio with unleade
d petrol, see Owner's Manual.
Drive the vehicle for at leas
t 5 minutes without interrupti
on, if biofuel Ethanol E85
has been refuelled, so that the engine co
ntrol unit can determine the share of the
biofuel in the fuel. During this period do
not drive at top speed
of your vehicle or
high engine speeds and not at full throttle
. During this process
decrease the idling
speed.
WARNING
Pay attention to any legal requirements if you do carry a spare canister in the vehicle. We do not recommend carrying
any fuel canisters in your vehicle for
safety reasons. The canister can be da
maged in the event of an accident and
fuel may leak out.

Caution
•
Even inadvertently filling the fuel tank
with another biofuel such as Ethanol°E85
can result in damage to the fuel system.•
If you park the car for a lengthy period,
fill with petrol complying with (DIN)
EN°228, because Ethanol E85 can contain lo
w quantities of impurities, which can
lead to corrosion.
For the sake of the environment
If you use Ethanol E85, the CO
2 emission of your vehicl
e is lowered up to 5%.
Note
•
When operating with Ethanol E85, the
fuel consumption increases by approx
33%, as a lower quantity of energy is contained in the bioethanol than in unleaded petrol.•
Biofuel Ethanol E85 contains only a low
quantity of additives in contrast to
unleaded petrol. Therefore we recommend to
fill up the tank with unleaded petrol
complying with EN 228 every 15 000 km (e.g. before the oil change) and run it empty, so that the engine remains clean. Make sure not to use the whole content of the tank
⇒page 222, “Refuelling”.
•
The interval of 15 000 km applies for the oil change.
Operation in winterIf you use biofuel Ethanol E85 at very low
temperatures, it is necessary to preheat
the engine before an engine start. The power socket for the engine preheating
is located in the front bumper next to
the fog light
⇒fig. 204
.
If an engine preheating is
not possible at outside temperatures lower than -10 °C,
the share of unleaded petrol complying with
EN 228 must be as high as possible.
Thus the cold start property of the engine is clearly improved. If there is biofuel Ethanol E
85 in the tank and the engine is not preheated, it can lead
at temperatures below -15°C to very poor or no starting of the engine.
For the sake of the environment
The use of engine preheating at temperatures below -10°C has a positive effect on the fuel consumption and thus on the environment.The outside temperature
Duration of engine preheating
lower than -10 °C
we recommend up to 1 hour
lower than -15 °C
at least 1 hour
lower than -25 °C
at least 2 hour

An extension cable used for

luggage compartment.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 p
oor, it is then necessary to drain the
fuel filter

more often than stated in the Service schedule. You can find information on refuelling
⇒page 222, “Refuelling”.
Caution
•
Only use fuel which complies with the standard
DINEN590
. Filling the tank
even only once, which does not comply with
the standard, can result in damage to
the fuel system.•
Water which has collected in the fuel fi
lter can result in engine problems.
•
Your vehicle is not adapted for use of biodiesel, therefore this fuel must not be
refuelled and driven. Using this biodiesel ca
n 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 be
comes 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 corres
ponding 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 different climatic conditions that diesel fuels available have a different temperature characteristic. The authorised Škoda Service Partners and filling stations in the country concerned will be able to provide you with information 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.
