2015 SKODA OCTAVIA fuel consumption

In Infotainment, the display is shown of up to three consumers which are cur-
rently showing the highest degree of fuel consumption » Owner´s Manual In-
fotainment , chapter CAR - vehicle settings .
Use the cooling system economically
The air conditioning system compressor uses power from the engine when in cooling mode, which will affect the fuel consumption.
It recommended to open the windows or the doors of a vehicle for which the
interior has been strongly heated through the effect of direct sunlight in order
to allow the heated air to escape.
The cooling system should not be on if the windows are open.

Incorrect refuelling guard on vehicles with diesel engines
The fuel filler tube on vehicles with diesel engines has been fitted with a in-
correct refuelling guard » Fig. 200. This guard means it is only possible to re-
fuel with the diesel pump nozzle.
If the diesel pump nozzle does not sit directly in the fuel filler tube, move it to
and fro with slight pressure to insert it correctly.
WARNINGInstructions for filling the reserve canister■Never fill the reserve can inside the vehicle.■
Never place the reserve can on the vehicle.
■
Always place the reserve can on the floor.
■
We do not recommend carrying any fuel canisters in your vehicle for safe-
ty reasons. in the event of an accident this can get damaged and fuel may
escape – risk of fire!
CAUTION
■ 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. Not continue refuelling.■
Be careful when filling diesel fuel from the spare canister and then do this
slowly and cautiously – danger of contaminating the body.
■
The diameter of the diesel pump nozzle can be identical to that of the petrol
pump nozzle in some countries. When driving in these countries, the incorrect
fuelling protection should be removed by a specialist company.
Note
The fuel tank has a capacity of about 50 litres, including a reserve of approx.
6 litres .Lead-free petrol
The correct fuel grades for your vehicle are specified on the inside of the fuel
filler flap.
Read and observe
and on page 189 first.
The vehicle can only be operated with unleaded petrol that meets the EN 2281)
standard.
All petrol engines can be operated using petrol that contains at most 10% bio-
ethanol (E10).
Unleaded petrol 95/91 or 92 or 93 RON/ROZ
We recommend using unleaded fuel with an octane rating of 95 RON. Unlea-
ded petrol with the octane ratings 91, 92 or 93 RON can also be used, but may
result in a slight loss in performance and slightly increased fuel consumption.
Unleaded petrol min. 95 RON / ROZ
Use unleaded fuel with the octane rating 95 RON or higher.
In an emergency petrol with the octane ratings 91, 92 and/or 93 RON can also
be used, but may result in a slight loss in performance and slightly increased
fuel consumption. Continue driving at medium engine speeds and minimum
engine load »
.
Refuel using petrol of the prescribed octane number as soon as possible.
Unleaded petrol 98/(95) RON / ROZ
We recommend using unleaded fuel with an octane rating of 98 RON or higher.
Unleaded petrol 95 RON can also be used but this results in a slight loss in per-
formance and slightly increased fuel consumption.
In an emergency petrol with the octane ratings 91, 92 and/or 93 RON can also
be used, but may result in a slight loss in performance and slightly increased
fuel consumption. Continue driving at medium engine speeds and minimum

190General Maintenance

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) . There is a risk of causing severe damage to parts of the engine or ex-
haust 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 189 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. The ŠKODA Part-
ners and filling stations in the relevant country will be able to provide you with
information regarding the diesel fuels available. 

191Inspecting and replenishing

when the engine is restarted. This is not due to any system leakages but a
drop in pressure in the natural gas fuel tank due to technical reasons after a
cooling phase directly after refuelling.
The maximum lifetime of the gas tank is 20 years.
The capacity of the natural gas fuel tank is approximately 15 kg.
The capacity of the gasoline fuel tank is about 50 litres, of which about 6
lighters are in reserve.WARNING■
When refuelling, never get into the vehicle. If you have to get into your
vehicle in exceptional cases, touch a metal surface before you touch the
filling coupling again. This will avoid electrostatic discharges, which may
generate sparks. Sparks can cause a fire during refuelling.■
Natural gas is highly explosive and highly flammable.
Note
During the filling process sounds are heard which are harmless. If you are un-
sure which service station staff to use, ask the petrol station staff.
CNG

A G-TEC-vehicle may be operated with CNG and petrol.
In some countries, national legislation requires that vehicles with CNG opera-
tion be identified by one of the labels » Fig. 202.
Position of the CNG label » Fig. 202.
Natural gas quality and consumption
Depending on the natural gas supplier, the natural gas quality (heating value) may vary. The engine system adjusts automatically to the natural gas quality.
Automatically switching over from natural gas mode to petrol mode
The vehicle automatically switches from natural gas to petrol, for example, if
one of the following cases occurs. ▶ With an empty gas tank or not enough pressure in the tank.
▶ After refuelling with natural gas.
▶ At very low surrounding temperatures.
Use all the petrol in the fuel tank at lease once every six months until the
warning light 
illuminates and then refill with petrol. This is to ensure that
the fuel system functions correctly and to preserve the quality of the fuel.
Gas leak
If a gas leak is suspected (noticeable odour), proceed as follows. ▶ Stop the vehicle.
▶ Switch off the ignition.
▶ Put out any cigarettes, remove any spark-producing or incendiary items from
the vehicle and immediately switch the engine off.
▶ Open the doors and the boot lid to ventilate the vehicle sufficiently.
▶ Do not continue to drive if the odour persists.
▶ If it is not possible to leave an enclosed area with a vehicle with a gas leak
(e.g. in a tunnel, underpass, garage, ferry, etc.), call the emergency services
immediately.
Seek help from a specialist garage to correct the gas system fault.
In a traffic accident
If a gas leak is suspected in a traffic accident, proceed as follows.
▶ Switch off the ignition.
▶ Put out any cigarettes, remove any spark-producing or incendiary items from
the vehicle and immediately switch the engine off.
▶ Have all the occupants get out.
▶ Prevent people walking past/standing in the immediate vicinity of the acci-
dent vehicle. We recommend standing at least 10 metres from the vehicle.
▶ Inform the emergency services that it is a natural gas vehicle.
Regular gas system checks
Regular gas system checks must be carried out in a specialist workshop on
natural gas-powered vehicles. The vehicle owner is responsible for ensuring
tests are conducted properly. 193Inspecting and replenishing

WARNINGFor safety reasons, do no replace tyres individually.
Note
■ We recommend that any work on the wheels or tyres be carried out by a spe-
cialist garage.■
We recommend that you use wheel rims, tyres, full wheel trims and snow
chains from ŠKODA Original Accessories.
Notes on using wheels
Read and observe
on page 205 first.
During the first 500 km, new tyres do not offer optimum grip and appropriate
care should therefore be taken when driving.
Always fit the tyres with the deeper tread depth to the front wheels.
Tyre storage
Mark them previously used tyres so that you are able to fit them on again to
run in the same direction.
Always store wheels or tyres in a cool, dry and, where possible, dark place.
Tyres which are not fixed to a wheel trim should be stored upright.
Tyre age
Tyres age losing their original characteristics, even if they are not used. The
service life of the tyres is 6 years. Therefore, we recommend not using tyres
that are more than 6 years old.
Wheel bolts
Wheels and wheel bolts are matched to each other in terms of design. We rec-
ommend that you use wheel rims and wheel bolts from ŠKODA Original Acces-
sories.WARNINGNever use tyres if you do not know anything about the condition and age.

The approved tyre sizes for your vehicle are listed in the vehicle's technical
documentation (COC document) and this also states the declaration of
conformity.
The approved tyre diameter for your vehicle is also provided with the vehi-
cle data » page 236 .
Tyre pressure value on the front axle
Tyre pressure value on the rear axle
Checking the tyre pressures
Check the tyre pressure, including that of the emergency or spare wheel, at
least once a month and also before setting off on a long journey.
Always check the inflation pressure when the tyres are cold. Do not reduce the
higher pressure on warm tyres.
In vehicles with tyre pressure monitoring, tyre pressure values must be saved
each time the pressures are changed » page 165.WARNING■
Having the correct tyre inflation pressure is always the driver's responsi-
bility.■
Too low or too high inflation pressure impairs handling.
■
If the inflation pressure is too low, the tyre must perform a greater rolling
resistance. At higher speeds the tyre will warm up as a result of this. This
can result in tread separation and a tyre blow-out.
■
In the event of very fast pressure loss, e.g. in the event of sudden tyre
damage, an attempt should be made to bring the vehicle carefully to a stop
without sudden steering movements and without any hard braking.
For the sake of the environment
Tyres which are insufficiently inflated increase your fuel consumption.
Note
The declaration of conformity (COC document) can be obtained from a ŠKODA 1)
partner.EFGTyre wear
Read and observe
on page 205 first.
The tyre wear depends on the tyre pressure, the driving style and other condi-
tions.
Attention to the following notes may affect tyre wear.
Driving style
Fast cornering, sharp acceleration and braking increase the wear of your tyres.
Wheel balance
The wheels of a new vehicle are balanced. When driving, there are a wide
range of influences which may result in an imbalance. This may become appa-
rent by a “vibration” in the steering. If this is the case, have the wheels
checked by a specialist garage.
Have the wheels rebalanced after replacing or repairing the tyres.
Setting the vehicle geometry
Incorrect wheel alignment at the front or rear leads to excess wear on the
tyres and impairs driving safety. In the event of prominent tyre wear, we rec-
ommend that you have the setting of the vehicle geometry checked at a spe-
cialist garage.
WARNING■ An incorrect wheel alignment at the front or rear impairs handling.■Unusual vibrations or pulling of the vehicle to one side could be a sign of
tyre damage. If there is any doubt that a wheel is damaged, immediately re-
duce your speed and stop! If no external tyre damage is evident, drive slow-
ly and carefully to the nearest specialist garage to have the vehicle
checked.1)
