fuel additives SKODA SUPERB 2015 3.G / (B8/3V) Owner's Manual

Fuel additives
Unleaded petrol in accordance with the EN 228 standard 1)
meets all the condi-
tions for a smooth-running engine. We therefore recommend that no fuel ad-
ditives are used. This can result in considerable damage to parts of the engine
or the exhaust system.
CAUTION
■ Even one filling of the tank with petrol that does not meet the standards can
lead to serious damage to parts of the exhaust system!■
If a fuel other than unleaded fuel which complies to the above mentioned
standards (e.g. leaded petrol) is put in the tank by mistake, do not start the en-
gine or switch on the ignition. Extensive damage to engine parts can occur.
CAUTION
■ If petrol with a lower octane number than the one prescribed is used do not
drive with a high engine speed. A high engine load can severely damage en-
gine components.■
Even in the event of an emergency, petrol of a lower octane number than 91
RON must not be used, otherwise the engine can be severely damaged.
CAUTION
In no case may fuel additives with metal components be used, especially not
with manganese or iron content. There is a risk of causing severe damage to
parts of the engine or exhaust system.
CAUTION
Do not use fuels with metal components, such as LRP (lead replacement
petrol) may be used. There is a risk of causing severe damage to parts of the
engine or exhaust system.Note■ Unleaded petrol that has a higher octane number than that required by the
engine can be used without limitations.■
The use of petrol with an octane rating higher than 95 RON in does not re-
sult in either a noticeable increase in power nor lower fuel consumption in ve-
hicles for which unleaded petrol 95/min 92 or 93 RON is specified.
■
On vehicles using prescribed unleaded petrol of min. 95 RON, the use of pet-
rol with a higher octane number than 95 RON can increase the power and re-
duce fuel consumption.
Diesel fuel
The correct fuel grades for your vehicle are specified on the inside of the fuel
filler flap.
Read and observe
and on page 201 first.
The vehicle can only be operated with diesel fuel that meets the EN 5902)
standard.
All diesel engines can be operated using diesel fuel with at most 7% biodiesel
(B7) 3)
.
On the Indian market, your vehicle will only be able to run on diesel fuel com-
pliant with standard IS 1460/Bharat IV. If diesel fuel which complies with this
standard is not available, you can refuel with diesel fuel according to standard
IS 1460/Bharat III in case of emergency.
Operation in winter - winter-grade diesel fuel
In the cold season, only use “winter-grade diesel fuel” which will still operate
properly even at a temperature of -20 °C.
It is often the case in countries with different climatic conditions that diesel
fuels available have a different temperature characteristic. ŠKODA Partners
and filling stations in the relevant country will be able to provide you with in-
formation regarding the diesel fuels available. 
1)
In Germany also DIN 51626-1 or E10 for unleaded petrol with octane number 91 or 95 or DIN 51626-2 or E5
for unleaded petrol with octane number 95 and 98.
2)
In Germany also DIN 51628, in Austria ÖNORM C 1590, in Russia GOST R 52368-2005 / EN 590:2004.
3)
In Germany according to the DIN 52638 standard, in Austria ÖNORM C 1590, in France EN 590.
203Inspecting and replenishing

Preheating fuel
The vehicle is fitted with a fuel filter preheating system. This secures opera-
tion of a vehicle using diesel fuel down to an environmental temperature of
-24 °C.
Diesel fuel additives
The diesel fuel in accordance with the prescribed standards meets all the con-
ditions for a smooth running engine. We therefore recommend that no diesel
fuel additives are used. This can result in considerable damage to parts of the
engine or the exhaust system.
CAUTION
■ Just filling the tank once with diesel fuel that does not comply with the
standard, can cause severe damage to parts of the engine, the fuel and ex-
haust system.■
If a different fuel other than diesel fuel, which complies to the above men-
tioned standards (e.g. petrol) is put into the tank, do not start the engine or
switch on the ignition! Extensive damage to engine parts can occur.
■
Water which has collected in the fuel filter can cause engine faults.
CAUTION
■ The vehicle cannot be operated with biofuel RME, therefore this fuel must
not be refuelled and driven. The use of biofuel RME can cause considerable
damage to parts of the engine or fuel system.■
Do not mix any fuel additives, so-called “flow improvers” (petrol and similar
agents) into the diesel. This can result in considerable damage to parts of the
engine or the exhaust system.
AdBlue ®
and its refilling
 Introduction
This chapter contains information on the following subjects:
Tank and level check

205
In order to reduce pollutant emissions from vehicles with diesel engines and
the SCR catalyst, a urea - AdBlue ®
solution is injected into the exhaust system.
For vehicles with the AdBlue ®
injection system there is a note on the inside of
the fuel filler flap referring to the location of the AdBlue ®
filler neck and the
AdBlue ®
- minimum replenishment amount, that is required by a low AdBlue ®
-
level.
AdBlue ®
standard
Only use AdBlue ®
that corresponds to the standard ISO 22241-1.
AdBlue ®
- consumption
The AdBlue ®
consumption amounts to around 0.8 - 1.2 l / 1000 km.
The AdBlue ®
consumption depends on driving style, the operating tempera-
ture of the system and on the weather conditions.
For information on storing AdBlue ®
▶ Keep AdBlue ®
only in original sealed containers and in a safe place.
▶ Keep the container out of the reach of children.
▶ Do not expose the containers to direct sunlight or temperatures above 30° C.
Instructions for cleaning ▶ If any painted vehicle parts, clothing and carpets are splashed with AdBlue ®
wash the affected area with a damp cloth and plenty of cold water.
▶ Remove any dried AdBlue ®
with warm water and a sponge.
Fault display
In the event of a system fault, the warning light  is displayed in the instru-
ment cluster as well as the relevant notification » page 39.WARNING■
AdBlue ®
is an irritating and corrosive solution that can injure the skin,
eyes and respiratory system!■
In the event of eye or skin contact with AdBlue ®
, immediately wash the
affected area for at least 15 minutes with water and seek medical attention
immediately.
■
If AdBlue ®
is swallowed rinse your mouth with water for at least 15 mi-
nutes and consult a doctor immediately.
CAUTION
■ Never carry containers with AdBlue ®
permanently in the vehicle - there is a
risk of damage to the vehicle interior.■
Never add water or other additives AdBlue ®
