Grades of petrol

•

There are various grades of petrol. Please read ⇒ page 271, “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 222, fig. 206.

damage at high revolutions or severe engine loading.

Biofuel Ethanol E85*

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.

Ethanol E85*

Only valid for vehicles with 1.6/75°kW MultiFuel engine.

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.

Biofuel Ethanol E85 consists of 85% bioethanol and 15% unleaded petrol

complying with the standard (DIN) EN°228.

Biofuel Ethanol E85 in accordance with the standard (DIN) EN 228 can be mixed in

any desired ratio with unleaded petrol, see Owner's Manual.

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.

Drive the vehicle for at least 5 minutes without interruption, if biofuel Ethanol E85

has been refuelled, so that the engine control unit can determine the share of the

biofuel in the fuel. During this period do not drive at top speed of your vehicle or

high engine speeds and not at full throttle. During this process decrease the idling

speed.

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!

WARNING

Pay attention to any legal requirements if you do carry a spare canister in the

vehicle. We do not recommend carrying any fuel canisters in your vehicle for

safety reasons. The canister can be damaged in the event of an accident and

fuel may leak out.

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.

Operation in winter

Caution

Even inadvertently filling the fuel tank with another biofuel such as Ethanol°E85

can result in damage to the fuel system.

If you park the car for a lengthy period, fill with petrol complying with (DIN)

EN°228, because Ethanol E85 can contain low quantities of impurities, which can

lead to corrosion.

•

For the sake of the environment

If you use Ethanol E85, the CO emission of your vehicle is lowered up to 5%.

Fig. 204 MultiFuel - power

socket

Note

•

When operating with Ethanol E85, the fuel consumption increases by approx

33%, as a lower quantity of energy is contained in the bioethanol than in unleaded

petrol.

If you use biofuel Ethanol E85 at very low temperatures, it is necessary to preheat

the engine before an engine start.

The power socket for the engine preheating is located in the front bumper next to

the fog light ⇒ fig. 204.

•

Biofuel Ethanol E85 contains only a low quantity of additives in contrast to

unleaded petrol. Therefore we recommend to fill up the tank with unleaded petrol

complying with EN 228 every 15 000 km (e.g. before the oil change) and run it

empty, so that the engine remains clean. Make sure not to use the whole content of

the tank ⇒ page 222, “Refuelling”.

lower than -15 °C

lower than -25 °C

at least 2 hour

If an engine preheating is not possible at outside temperatures lower than -10 °C,

the share of unleaded petrol complying with EN 228 must be as high as possible.

Thus the cold start property of the engine is clearly improved.

If there is biofuel Ethanol E85 in the tank and the engine is not preheated, it can lead

at temperatures below -15°C to very poor or no starting of the engine.

For the sake of the environment

The use of engine preheating at temperatures below -10°C has a positive effect on

the fuel consumption and thus on the environment.

Operation in winter

Note

An extension cable used for connecting to the electrical network is located in the

luggage compartment.

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.

Diesel

It is therefore the case that DIN EN 590 prescribes diesel fuel class 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.

Diesel fuel

Your vehicle can be operated with diesel fuel, which complies with the standard

DIN EN 590.

It is often the case in countries with different climatic conditions that diesel fuels

available have a different temperature characteristic. The authorised Škoda Service

Partners and filling stations in the country concerned will be able to provide you

with information regarding the diesel fuels available.

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

Prewarming fuel

more often than stated in the Service schedule.

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.

You can find information on refuelling ⇒ page 222, “Refuelling”.

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.

•

Only 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 biodiesel, therefore this fuel must not be

refuelled and driven. Using this biodiesel can lead to damage to the engine or the

fuel system.

•

Make sure that the valve is not pressed into the filler tube when inserting the

pump nozzle into the filler tube. Otherwise you are unintentionally filling up the

volume, which in case of heat can cause an expansion of the fuel. This can lead to

an overflow of fuel or damage to parts of the fuel reservoir.

•

The fuel tank is full just as soon as the pump nozzle switches off for the first time,

provided the nozzle has been operated properly. Do not continue refuelling -

otherwise the expansion volume is filled up.
