Grades of petrol
There are various grades of petrol. Please read the brochure “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 188, fig. 137 .
A distinction is made between unleaded and leaded petrol. All Škoda vehi-
cles with petrol engines are equipped with a catalytic converter and must
therefore be only driven with unleaded petrol. Unleaded petrol complies
with the standard 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 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 petrol of 91 RON in the event that no unleaded
premium plus petrol of 98 RON or premium plus petrol of 95 RON is avail-
able. 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!
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 188.
Caution
•Filling the tank even only once with leaded petrol will result in the cata-
lytic converter being destroyed.
•Operating the engine with petrol of a low octane number than that
required can result in engine damage at high revolutions or severe engine
loading.
