Grades of petrol
There are various grades of petrol. Please read ⇒ page 227 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
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.
•
Engines which need unleaded premium plus petrol 98 RON can also be run
on unleaded regular petrol 95 RON. This does, however, result in a slight loss in
performance. You can in exceptional circumstances also use unleaded regular
petrol of 91 RON in the event that neither unleaded premium petrol of 98 RON nor
95 RON is available. Refuel as soon as possible with unleaded premium plus of 98
RON or unleaded premium petrol of 95 RON.
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!

Driving Tips
General Maintenance
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 182, "Refuelling".
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
Type of diesel
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 182, "Refuelling".
Caution
•
Use a fuel complying with the standard. 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.
