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 195, fig. 140.
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 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 availabl e 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. Th is 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 av ailable 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 yo ur engine are determined to a signifi- cant extent by the quality of the fu el. Do not use any petrol additives. Use a fuel complying with the standard.
You can find further info rmation on refuelling ⇒page 195.
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 than that required 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 EN 590.
It is prohibited to use biofuel (RME) and diesel fuel mixture.
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 195, “Refuelling”.
Caution
•Use a fuel which complies with the standard EN 590. Filling the tank even only once, which does not comply with th is standard, can result in damage to the fuel system.
•Water which has collected in the fuel fi lter can result in engine problems.
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 result in operational problems because the diesel becomes viscous as a result of paraffin separation.
It is therefore the case that EN 590 prescribes diesel fuel class for certain periods of the year which can also be purchase d 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 diff erent climatic conditions that diesel fuels available have a different temperature characteristic. Škoda Service Partners and filling stations in the country concer ned 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 petrol, to diesel fuel in order to improve its flow properties.
