Fuel
Petrol
Unleaded petrol Your vehicle can only be operated with
unleaded petrol, which complies with the
standard EN 228 (In Germany: standard DIN 51626 - 1 or E10 for unleaded fuel with
octane rating 95 RON and 91 RON or DIN 51626 - 2 or E5 for unleaded fuel with
octane rating 95 RON and 98 RON). On the inside of the fuel filler flap, you will
find the information regarding the RON required by your engine ⇒
 fig. 150 - right.
Prescribed fuel - unleaded petrol 95/91 RON
Use unleaded fuel with the octane rating 95 RON. You can also use unleaded pet-
rol 91 RON, but this leads to a slight loss in performance.
If, in case of necessity, the vehicle must be refuelled with petrol of a lower octane
number than the one prescribed, you must continue driving at medium engine
speeds and low engine load. Driving at high engine revs or a high engine load can
severely damage the engine! Refuel as soon as possible with petrol of the prescri-
bed octane number.
Prescribed fuel - unleaded petrol min. 95 RON
Use unleaded fuel with the octane rating 95 RON.
In case of necessity, you can refuel with petrol with the octane rating 91 RON if
petrol with the octane rating 95 RON is not available. You must continue driving at
medium engine speeds and minimum engine load. Driving at high engine revs or a
high engine load can severely damage the engine! Refuel as soon as possible with
petrol of the prescribed octane number.
Even in case of necessity, you must not use petrol of a lower octane number than
91 RON, otherwise the engine can be severely damaged!
You can find further information on refuelling ⇒ page 187, Refuelling.
Unleaded petrol with higher octane number
You can make unlimited use of unleaded petrol which has a higher octane number
than the one prescribed.
On vehicles with prescribed unleaded petrol 95/91 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 with prescribed unleaded petrol
min. 95 RON, the use of petrol with a
higher octane number than 95 RON does not result in a power increase or a lower
fuel consumption.
Prescribed fuel - unleaded petrol 98/95 RON
Use unleaded fuel with the octane rating 98 RON. You can also use unleaded pet-
rol 95 RON, but this leads to a slight loss in performance.
In case of necessity, you can refuel with petrol with the octane rating 91 RON of
unleaded fuel with octane rating 98

RON or 95 RON is not available. You must
continue driving at medium engine speeds and minimum engine load. Driving at
high engine revs or a high engine load can severely damage the engine! Refuel as
soon as possible with petrol of the prescribed octane number.
Even in case of necessity, you must not use petrol of a lower octane number than
91 RON, otherwise the engine can be severely damaged!
Fuel additives
Your vehicle can only be operated with unleaded petrol, which complies with the
standard EN 228 (in Germany: standard DIN 51626 - 1 or E10 for unleaded fuel with
octane rating 95 RON and 91 RON or DIN 51626 - 2 or E5 for unleaded fuel with
octane rating 95 RON and 98 RON). These meet all requirements for troublefree
engine operation. Therefore, we do not recommend the use of fuel additives. CAUTION
● All
ŠKODA vehicles with petrol engines are equipped with a catalytic converter
and must be driven only with unleaded petrol. Filling the tank even only once with
leaded petrol will result in the catalytic converter being destroyed!
● If you use petrol with a lower octane number than the one prescribed, the en-
gine can be severely damaged!
● The use of improper fuel additives can cause serious damage to the engine or
the catalytic converter. In no case may fuel additives with metal components be
used, especially not with manganese and iron content.
● Fuels with metallic content may not be used. Risk of engine or catalytic con-
verter damage!
● LRP (lead replacement petrol) fuels with metallic components may not be
used. Risk of engine or catalytic converter damage! 186
Fuel

Diesel
Diesel fuel Your vehicle can only be operated with
diesel fuel, which complies with the stand-
ard EN 590 (standard DIN 51628 in Germany, standard ÖNORM
C 1590 in Austria,
GOST R 52368-2005/EN 590:2004 in Russia).
Fuel additives
You must not use fuel additives, so-called “flow improvers” (petrol and similar
products) in diesel fuel.
You can find information on refuelling ⇒ page 187, Refuelling. CAUTION
● Your vehicle can only be operated with diesel fuel, which complies with the
standard EN 590 (standard DIN 51628 in Germany, standard ÖNORM

C 1590 in
Austria, GOST R 52368-2005/EN 590:2004 in Russia). Filling the tank even only
once with diesel fuel which does not comply with the standard, can result in dam-
age to the engine parts, the lubrication system, the fuel and exhaust system.
● If by mistake you have refuelled with a different fuel other than the diesel fuel
which complies to the above mentioned standards (e.
g. petrol), do not start the
engine or switch on the ignition! Severe damage damage is possible! Contact a
specialist garage and have the fuel system of the engine cleaned.
● Water which has collected in the fuel filter can result in engine problems.
● Your vehicle is not adapted for use of biofuel (RME), therefore this fuel must
not be refuelled and driven. The use of biofuel (RME) can lead to damage to the
engine or the fuel system. 
Operation in winter Winter-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 re-
sult in operational problems because the diesel becomes viscous as a result of
paraffin separation. It is therefore the case that the standard
EN 590 (standard DIN 51628 in Germany,
standard ÖNORM

C 1590 in Austria, GOST R 52368-2005/EN 590:2004 in Russia)
is the diesel fuel class prescribed for certain periods of the year which can also be
purchased 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 different climatic conditions that diesel fuels
available have a different temperature characteristic. The authorised ŠKODA Serv-
ice 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 pet-
rol, to diesel fuel in order to improve its flow properties. 

Fuel Using the system Safety Driving Tips General Maintenance Breakdown assistance Technical data

It is normal for the engine to consume oil. The oil consumption may be as much as
0.5 l/1 000 km depending on your style of driving and the conditions under which
you operate your vehicle. The oil consumption may be slightly higher than this
during the first 5 000 kilometres.
One should therefore check the oil level at regular intervals, preferably every time
after the fuel tank is filled or after driving for long stretches.
We recommend maintaining the oil level within the range A - but not above this
,
if the engine has been operating at high loads, for example during a lengthy mo-
torway trip during the summer months, towing a trailer or negotiating a high
mountain pass.
The warning light in the instrument cluster will indicate whether the oil level is
too low ⇒ page 25. In this case, check the oil level as soon as possible. Top up with
an appropriate quantity of oil. CAUTION
● The oil level must on no account extend beyond the range A . Danger of dam-
aging the catalytic converter.
● Do not continue your journey if for some reason it is not possible under the
conditions prevailing to top up with oil. Switch the engine off and obtain profes-
sional assistance from a specialist garage, otherwise it could lead to severe en-
gine damage. Note
Engine oil specifications ⇒  page 228, Technical data. 
Replenishing engine oil –
Inspecting the engine oil level ⇒
 page 191.
– Unscrew the cap of the engine oil filler opening.
– Pour in a suitable grade of oil in portions of 0.5 litres ⇒ page 231, Engine oil
specifications.
– Inspect the oil level ⇒ page 191
.
– Carefully screw on the cap of the filler opening and push the dipstick in fully. WARNING
● Avoid dripping oil onto hot parts of the engine when topping up will oil - a
risk of fire!
● Read and observe the warning notes ⇒
 page 190, Working in the engine
compartment before working in the engine compartment. For the sake of the environment
The oil level must on no account extend beyond the range A ⇒
 
page 191. Oil will
otherwise be drawn in through the crankcase ventilation and may pass through
the exhaust system to atmosphere. The oil may combust in the catalytic converter
and damage it. 
Changing engine oil The engine oil must be changed at the intervals stated in the Service schedule or
according to the service interval indicator
⇒ page 12, Service reminder indicator

. WARNING
● Only carry out the engine oil change, if you have the required professional
knowledge!
● Read and observe the warning notes ⇒
 page 190, Working in the engine
compartment before working in the engine compartment.
● First of all, let the engine cool down, wear an eye protection and gloves -
risk of caustic burns due to hot oil. CAUTION
You must not pour any additives into the engine oil - risk of engine damage! Dam-
age, which results from such product, are excluded from the warranty. For the sake of the environment
● You must on no account pour oil into the ground or into the sewage system.
● In view of the problems involved in properly disposing of old oil, the necessary
special tools and the knowledge required for such work, we recommend that you
have the oil and oil filter change carried out by an authorised
