octane SKODA CITIGO 2017 Owners Manual

CAUTION■Never drive until the fuel tank is completely empty! Irregular supply of fuel
can cause misfiring, which can result in damage to parts of the engine and the
exhaust system.■
Immediately remove any fuel that has spilled onto the vehicle's paintwork –
risk of paint damage.
■
If you would like to operate your vehicle in a country other than the one for
which it was intended, please talk to a ŠKODA Partner. They will tell you
whether the fuel specified by the manufacturer is offered in that country
and/or whether the manufacturer will sanction operating the vehicle with
another fuel.

Unleaded petrol
Read and observe
and on page 117 first.
The correct fuel for your vehicle is specified on the inside of the fuel filler
flap » Fig. 132 on page 117 .
The vehicle can only operate with unleaded petrol that meets standard EN
228 1)
, and contains maximum 10% bioethanol (E10).
Specified petrol is 95 RON / ROZ
The petrol min. 95 Use ROZ.
In an emergency , 91 . 92 or 93 ROZ petrol can be used (slight loss of power,
slightly increased fuel consumption) »
.
CAUTION
The following instructions must be observed, otherwise there is a risk of dam-
age to the engine and to the exhaust system.■
When petrol with a lower than the prescribed octane is used, only continue
driving at mid-range engine speeds and with minimal strain on the engine. Re-
fuel using petrol of the prescribed octane number as soon as possible.
■
Lower than 91 octane petrol should not be used, even in an emergency!
■
If a fuel other than unleaded fuel which complies to the above mentioned
standards (e.g. leaded petrol) is put in the tank by mistake, do not start the en-
gine or switch on the ignition. 
1)
In Germany, DIN 51626-1 or E10 for unleaded gasoline with octane number 95 and 91.
118General Maintenance

CAUTIONPetrol additives (additives)■Unleaded petrol complying with the EN 228 standard1)
meets all the condi-
tions for problem-free engine operation. We therefore do not recommend mix-
ing fuel additives into the petrol - risk of engine damage or damage to the ex-
haust system.■
The following additives may not be used - risk of engine damage or damage
to the exhaust system! ■ Additives with metal components (metallic additives), in particular with
manganese and iron content.
■ Fuels with metallic content (e.g. LRP - lead replacement petrol).
Note
■Unleaded petrol that has a higher octane number than that required by the
engine can be used without limitations.■
On vehicles using the prescribed unleaded petrol of min. 95 RON, the use of
petrol with a higher octane number than 95 RON can lead to an increase in
power and reduction in fuel consumption.
Refuelling with CNG (compressed natural gas)
Fig. 134
Natural gas filler tubes
Read and observe
and on page 117 first.
Natural gas refuelling may vary from station to station. When refuelling with natural gas at a station unfamiliar to you, you should get someone to instruct
you or allow the fuelling operation carried out by the station staff.
Refuelling operation›Switch off the ignition.›
Open the fuel filler flap.

The fuel tank is full when the compressor of the refuelling system automati-
cally switches off.

. If
the sealing ring has slipped on the connector, reinsert it into the filler neck.

into the filler neck and close the fuel filler flap until it locks into
place.
The natural gas refuelling systems have an overfill protection relating to the
outdoor temperature. At very high outside temperatures, it may happen that
the gas tank may not be fully refuelled.
If the car is parked directly after a refuelling operation, on restart the pointer
of the gas gauge may not show exactly the same level as immediately after
the filling process. This is not a leak in the system, but a reduction in pressure
due to the cooling of the gas in the gas tank after refuelling.
The maximum lifetime of the gas tank is 20 years.
The capacity of the natural gas fuel tank is about 11 kg, of which about 1.5 kg
are in the reserve tank.
The capacity of the petrol fuel tank is approximately 10 litres, of which about 5
litres is in the reserve tank.
WARNING■
Natural gas is highly explosive and highly flammable.■When refuelling, never get into the vehicle. If you have to get into your
vehicle in exceptional cases, touch a metal surface before you touch the
filling coupling again. Otherwise, electrostatic discharging may occur - risk
of fire!
Note
During the filling process sounds are heard which are harmless. If you are un-
sure which service station staff to use, ask the petrol station staff.1)
