Fuel

Petrol

Grades of petrol
There are various grades of petrol. Please read ⇒ page 267, "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 220, fig.
199.
A distinction is made between unleaded and leaded petrol. All Škoda vehicles with
petrol engines are equipped with a catalytic converter and must therefore be only
driven with unleaded petrol. Unleaded petrol complies with the standard
DIN EN 228.
The individual grades of petrol 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 available 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 which has a higher octane number than that
required by the engine. There will, however, 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 220, "Refuelling".
Using the system Safety Driving Tips General Maintenance
Caution
•
Filling the tank even only once with leaded petrol will result in the catalytic
converter being destroyed.
•
Operating the engine with petrol of a low octane number can result in engine
damage at high revolutions or severe engine loading.

Diesel

Diesel fuel
Your 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 220, "Refuelling".
Caution
•
Use fuel which complies with the standard DIN EN 590. 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 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. Using this fuel (RME) can lead to damage to the engine or
the fuel system.
