Skoda CITIGO Owner's Manual page 111

The vehicle can only be operated with unleaded petrol containing a maximum
of 10% bioethanol (E10).
Unleaded petrol must meet European standard EN 228 (in Germany DIN
51626-1 or E10 for unleaded petrol with octane numbers 95 and 91).
Specified petrol is 95 RON / ROZ
Use min. 95 RON petrol.
In an emergency, 91. 92 or93 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.
CAUTION
Petrol additives (additives)
Unleaded petrol in accordance with the prescribed standards meets all the
■
conditions for a smooth running engine. 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 dam-
■
age 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. 136 Natural gas filler tubes

Read and observe and
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.
›
Remove cap » Fig. 136 in the direction of the arrow and insert connector
A
for the refuelling system into filler neck
The fuel tank is full when the compressor of the refuelling system automatical-
ly switches off.
›
Check that sealing ring » Fig. 136
C
the sealing ring has slipped on the connector, reinsert it into the filler neck.
›
Insert cap into the filler neck and close the fuel filler flap until it locks into
A
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.
