2011 SKODA OCTAVIA fuel consumption

Shifting gears and saving energy
Shifting up early saves on fuel.
Fig. 142 Fuel consumption in litres/100
km and speed in km/h.
Manual gearbox
– Drive no more than about one length of your vehicle in first gear.
– Shift up into the next higher gear at approx. 2 000 to 2 500 revs.
An effective way of achieving good fuel economy is to shift up early . You will con-
sume more fuel if you drive at unnecessarily high revolutions in any given gear. To
shift in a fuel-efficient manner, follow ⇒
 page 13, Shift recommendation for chang-
ing gears.
Automatic gearbox
– Depress the accelerator pedal slowly. Do not depress it beyond the kickdown
position, however.
Only depress the accelerator pedal slowly if your vehicle is fitted with an automat-
ic gearbox in order to automatically select an economic driving programme. You
will achieve good fuel economy by shifting up early and shifting down late.
General
The ⇒ fig. 142 shows the ratio of fuel consumption to the speed of your vehicle in
the relevant gears. Fuel consumption in 1st

gear is the highest, while that in 5th or
the 6th gear is the lowest. Note
Also use the information supplied by the multi-functional indicator ⇒ page 14.Avoiding full throttle Driving more slowly means saving fuel.
Fig. 143 Fuel consumption in litres/100
km. and speed in km/h.
Sensitive use of the accelerator will not only significantly reduce fuel consumption
but also positively influence environmental pollution and wear of your vehicle.
You should avoid exploiting the top speed of your vehicle wherever possible. Fuel
consumption, pollutant emissions and vehicle noises increase disproportionally at
high speeds.
The ⇒ fig. 143 shows the ratio of fuel consumption to the speed of your vehicle.
You will cut your fuel consumption by half if you only make use three-quarters of
the possible top speed of your vehicle. 
Reducing idling Idling also costs fuel.
It is worthwhile switching off the engine in a traffic jam or when waiting at a level
crossing or at traffic lights with a lengthy red phase. Even after just 30 - 40 sec-
onds you will have saved more fuel than that is needed when you start the engine
up again.
If an engine is only idling it takes much longer for it to reach its normal operating
temperature. Wear-and-tear and pollutant emissions, though, are particularly high
in the warming-up phase. This is why you should drive off right after starting the
engine. Do avoid high engine revolutions at this time, however.  163

Regular servicing
A poorly tuned engine uses an unnecessarily high amount of fuel.
Having your vehicle serviced regularly at a specialist garage enables you to satisfy
one of the requirements for economical motoring even before you set off on your
journey. Keeping your vehicle properly serviced not only has a positive effect on
the safety of your vehicle and maintaining its value, but also saves on fuel.
A poorly tuned engine can result in a fuel consumption which is 10 % higher than
normal.
The foreseen maintenance work should be undertaken exactly according to the
Service schedule by a specialist garage.
Also check the oil level after refuelling. Oil consumption is dependent to a consid-
erable extent on the load and speed of the engine. Oil consumption could be as
high as 0.5 litres/1 000 km depending on your style of driving.
It is quite normal that a new engine has a higher oil consumption at first, and rea-
ches its lowest level only after a certain running in time. It is therefore not possi-
ble to correctly assess the oil consumption of a new vehicle until after you have
driven about 5 000 km. For the sake of the environment
● You can achieve additional improvements in your fuel economy by using high-
lubricity oils.
● Check the ground below your car at regular intervals to detect any leakages in
good time. Please have your vehicle inspected by a specialist garage if you find
any stains caused by oil or other fluids on the floor. Avoid driving short distances Short distances result in an above-average high fuel consumption.
Fig. 144 Fuel consumption in litres/100
km at different temperatures
– Avoid driving a distance of no more than 4 km if the engine is cold.
The engine and catalytic converter must first have reached their optimal operat-
ing temperature in order to effectively reduce fuel consumption and pollutant
emissions.
The cold engine vehicle consumes approx. 15 - 20 litres/100 km of fuel immediate-
ly after starting. Fuel consumption drops to 10 litres/100 km after just 1 kilometre.
The engine reaches its operating temperature (outside temperature and engine
dependent) only after about 4 to 10 kilometres and the fuel consumption then
stabilizes. You should therefore avoid driving short distances whenever possible.
An important factor in this connection is also the ambient temperature. The
⇒  fig. 144 shows the different fuel consumptions for the same distance, on the
one hand at +20 °C and on the other hand at -10
°C. Your vehicle has a higher fuel
consumption in winter than in summer. 
Checking tyre inflation pressures Tyres which are correctly inflated save fuel.
Always ensure that your tyres are inflated to the correct pressure at all times. The
rolling resistance will be increased if the tyre filling pressure is too low. This will
not only increase fuel consumption but also tyre wear and the driving behaviour
will worsen.
Always check the inflation pressure of the tyres when cold. £164
Driving and the Environment

Do not drive with winter tyres all year round for this costs about 10 % more fuel.
Winter tyres are also louder.

No unnecessary ballast Transporting ballast costs fuel.
The fact that every kilogram of extra weight increases your fuel consumption
means that it is worth taking a look in the luggage compartment to avoid trans-
porting any unnecessary ballast.
It is particularly in town traffic, when one is accelerating quite often, that the vehi-
cle weight will have a significant effect upon the fuel consumption. A rule of
thumb here is that an increase in weight of 100 kilograms will cause an increase in
fuel consumption of about 1 litre/100 kilometres.
You may frequently also leave a roof rack fitted on just out of convenience, al-
though you no longer need it. The increased aerodynamic drag of your vehicle
causes it to use about 10 % more fuel than normal at a speed of 100 - 120 km/h,
even when you are not carrying a load on the roof. 
Saving electricity Generating electricity costs fuel.
– Switch off electrical components as soon as you no longer need them.
When the engine is running, the alternator generates and supplies electrical pow-
er. If more electrical components of the electrical system are switched on, more
fuel is needed to operate the alternator. 
Keeping a log of your fuel consumption If you really wish to keep a close check on your
fuel consumption, it is best to en-
ter the figures in a logbook. This does not take much time but is a very worthwhile
exercise. It enables you to detect any change (positive and negative) at an early
stage and to take any appropriate action.
If you find that your fuel consumption is too high, you should reflect on how,
where and in what conditions you have driven the vehicle since you last refuelled. Environmental compatibility Environmental protection has played a major role in the design, selection of mate-
rials and manufacture of your new ŠKODA. Particular emphasis has been paid to a
number of aspects, including:
Design measures
● Joints designed to be easily detached.
● Simplified disassembly due to the modular structure system.
● Improved purity of different classes of materials.
● Identification of all plastic parts in accordance with VDA Recommendation
°260.
● Reduced fuel consumption and exhaust emission CO
2.
● Minimum fuel leakage during accidents.
● Reduced noise.
Choice of materials
● Extensive use of recyclable material.
● Air conditioning filled with CFC-free refrigerant.
● No cadmium.
● No asbestos.
● Reduction in the “vaporisation” of plastics.
Manufacture
● Solvent-free cavity protection.
● Solvent-free protection of the vehicle for transportation from the production
plant to the customer.
● The use of solvent-free adhesives.
● No CFCs used in the production process.
● Without use of mercury.
● Use of water-soluble paints. £ 165

Fuel
Petrol
Unleaded petrol Your vehicle can only be operated with
unleaded petrol, which complies with the
standard EN 228 (In Germany: standard DIN 51626 - 1 or E10 for unleaded fuel with
octane rating 95 RON and 91 RON or DIN 51626 - 2 or E5 for unleaded fuel with
octane rating 95 RON and 98 RON). On the inside of the fuel filler flap, you will
find the information regarding the RON required by your engine ⇒
 fig. 147 - right.
Prescribed fuel - unleaded petrol 95/91 RON
Use unleaded fuel with the octane rating 95 RON. You can also use unleaded pet-
rol 91 RON, but this leads to a slight loss in performance.
If, in case of necessity, the vehicle must be refuelled with petrol of a lower octane
number than the one prescribed, you must continue driving at medium engine
speeds and low engine load. Driving at high engine revs or a high engine load can
severely damage the engine! Refuel as soon as possible with petrol of the prescri-
bed octane number.
Prescribed fuel - unleaded petrol min. 95 RON
Use unleaded fuel with the octane rating 95 RON.
In case of necessity, you can refuel with petrol with the octane rating 91 RON if
petrol with the octane rating 95 RON is not available. You must continue driving at
medium engine speeds and minimum engine load. Driving at high engine revs or a
high engine load can severely damage the engine! Refuel as soon as possible with
petrol of the prescribed octane number.
Even in case of necessity, you must not use petrol of a lower octane number than
91 RON, otherwise the engine can be severely damaged!
You can find further information on refuelling ⇒ page 178, Refuelling.
Unleaded petrol with higher octane number
You can make unlimited use of unleaded petrol which has a higher octane number
than the one prescribed.
On vehicles with prescribed unleaded petrol 95/91 RON, the use of petrol with a
higher octane number than 95 RON does not result in a noticeable power increase
or a lower fuel consumption. On vehicles with prescribed unleaded petrol
min. 95 RON, the use of petrol with a
higher octane number than 95 RON does not result in a power increase or a lower
fuel consumption.
Prescribed fuel - unleaded petrol 98/95 RON
Use unleaded fuel with the octane rating 98 RON. You can also use unleaded pet-
rol 95 RON, but this leads to a slight loss in performance.
In case of necessity, you can refuel with petrol with the octane rating 91 RON of
unleaded fuel with octane rating 98

RON or 95 RON is not available. You must
continue driving at medium engine speeds and minimum engine load. Driving at
high engine revs or a high engine load can severely damage the engine! Refuel as
soon as possible with petrol of the prescribed octane number.
Even in case of necessity, you must not use petrol of a lower octane number than
91 RON, otherwise the engine can be severely damaged!
Fuel additives
Your vehicle can only be operated with unleaded petrol, which complies with the
standard EN 228 (in Germany: standard DIN 51626 - 1 or E10 for unleaded fuel with
octane rating 95 RON and 91 RON or DIN 51626 - 2 or E5 for unleaded fuel with
octane rating 95 RON and 98 RON). These meet all requirements for troublefree
engine operation. Therefore, we do not recommend the use of fuel additives. CAUTION
● All
ŠKODA vehicles with petrol engines are equipped with a catalytic converter
and must be driven only with unleaded petrol. Filling the tank even only once with
leaded petrol will result in the catalytic converter being destroyed!
● If you use petrol with a lower octane number than the one prescribed, the en-
gine can be severely damaged!
● The use of improper fuel additives can cause serious damage to the engine or
the catalytic converter. In no case may fuel additives with metal components be
used, especially not with manganese and iron content.
● Fuels with metallic content may not be used. Risk of engine or catalytic con-
verter damage!
● LRP (lead replacement petrol) fuels with metallic components may not be
used. Risk of engine or catalytic converter damage! 176
Fuel

Biofuel Ethanol E85
Ethanol E85 Only valid for vehicles with 1.6/75°kW MultiFuel engine.
Biofuel Ethanol E85 consists of 85 % bioethanol and 15 % unleaded petrol com-
plying 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.
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. 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. 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 your vehicle 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 2 emission of your vehicle is lowered up to 5 %. 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 unlea-
ded petrol.
● Biofuel Ethanol E85 contains only a low quantity of additives in contrast to un-
leaded 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 178, Refuelling
.
● The interval of 15 000 km applies for the oil change. 
Operation in winter Fig. 146 MultiFuel - power socket
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. 146 . The outside temperature Duration of engine preheating
lower than -10
℃ We recommend up to 1 hour
lower than -15
℃ at least 1 hours.
lower than -25
℃ at least 2 hours.
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. £ 177

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. Note
An extension cable used for connecting to the electrical network is located in the
luggage compartment. 
Diesel Diesel fuel Your vehicle can only be operated with
diesel fuel, which complies with the stand-
ard EN 590 (standard DIN 51628 in Germany, standard ÖNORM
C 1590 in Austria,
GOST R 52368-2005/EN 590:2004 in Russia).
Fuel additives
You must not use fuel additives, so-called “flow improvers” (petrol and similar
products) in diesel fuel.
You can find information on refuelling ⇒ page 178, Refuelling. CAUTION
● Your vehicle can only be operated with diesel fuel, which complies with the
standard EN 590 (standard DIN 51628 in Germany, standard ÖNORM

C 1590 in
Austria, GOST R 52368-2005/EN 590:2004 in Russia). Filling the tank even only
once with diesel fuel which does not comply with the standard, can result in dam-
age to the engine parts, the lubrication system, the fuel and exhaust system.
● If by mistake you have refuelled with a different fuel other than the diesel fuel
which complies to the above mentioned standards (e.
g. petrol), do not start the
engine or switch on the ignition! Severe damage damage is possible! Contact a
specialist garage and have the fuel system of the engine cleaned.
● Water which has collected in the fuel filter can result in engine problems.
● Your vehicle is not adapted for use of biofuel (RME), therefore this fuel must
not be refuelled and driven. The use of biofuel (RME) can lead to damage to the
engine or the fuel system. 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 re-
sult in operational problems because the diesel becomes viscous as a result of
paraffin separation.
It is therefore the case that the standard EN 590 (standard DIN 51628 in Germany,
standard ÖNORM C 1590 in Austria, GOST R 52368-2005/EN 590:2004 in Russia)
is the diesel fuel class prescribed 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.
It is often the case in countries with different climatic conditions that diesel fuels
available have a different temperature characteristic. The authorised ŠKODA Serv-
ice Partners and filling stations in the country concerned will be able to provide
you with information regarding the diesel fuels available.
Preheating fuel
The vehicle is fitted with a fuel filter preheating 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 pet-
rol, to diesel fuel in order to improve its flow properties. 

Fuel

It is normal for the engine to consume oil. The oil consumption may be as much as
0.5 l/1 000 km depending on your style of driving and the conditions under which
you operate your vehicle. The oil consumption may be slightly higher than this
during the first 5 000 kilometres.
One should therefore check the oil level at regular intervals, preferably every time
after the fuel tank is filled or after driving for long stretches.
We recommend maintaining the oil level within the range A - but not above this
,
if the engine has been operating at high loads, for example during a lengthy mo-
torway trip during the summer months, towing a trailer or negotiating a high
mountain pass.
The warning light in the instrument cluster will indicate whether the oil level is
too low ⇒ page 25, Engine oil pressure . In this case, check the oil level as soon
as possible. Top up with an appropriate quantity of oil. CAUTION
● The oil level must on no account extend beyond the range A . Danger of dam-
aging the catalytic converter.
● Do not continue your journey if for some reason it is not possible under the
conditions prevailing to top up with oil. Switch the engine off and obtain profes-
sional assistance from a specialist garage, otherwise it could lead to severe en-
gine damage. Note

– Inspect the oil level ⇒ page 182
.
– Carefully screw on the cap of the filler opening and push the dipstick in fully. WARNING
● Avoid dripping oil onto hot parts of the engine when topping up will oil - a
risk of fire!
● Read and observe the warning notes ⇒
 page 181, Working in the engine
compartment before working in the engine compartment. For the sake of the environment
The oil level must on no account extend beyond the range A ⇒
 
page 182. Oil will
otherwise be drawn in through the crankcase ventilation and may pass through
the exhaust system to atmosphere. The oil may combust in the catalytic converter
and damage it. 
Changing engine oil The engine oil must be changed at the intervals stated in the Service schedule or
according to the service interval indicator
⇒ page 12, Service reminder indicator

. WARNING
● Only carry out the engine oil change, if you have the required professional
knowledge!
● Read and observe the warning notes ⇒
 page 181, Working in the engine
compartment before working in the engine compartment.
● First of all, let the engine cool down, wear an eye protection and gloves -
risk of caustic burns due to hot oil. CAUTION
You must not pour any additives into the engine oil - risk of engine damage! Dam-
age, which results from such product, are excluded from the warranty. For the sake of the environment
● You must on no account pour oil into the ground or into the sewage system.
● In view of the problems involved in properly disposing of old oil, the necessary
special tools and the knowledge required for such work, we recommend that you
have the oil and oil filter change carried out by an authorised

Inspecting and Replenishing Using the system Safety Driving Tips General Maintenance Breakdown assistance Technical data

The tyre inflation pressure for tyres of the tyre size 205/50 R17, which are inten-
ded to be used with snow chains, is identical to the tyre inflation pressure for
tyres of the tyre size 225/45
R17, see ⇒ fig. 157.
The tyre pressure should be at the highest pressure specified for your vehicle at
all times.
The tyre inflation pressure of the emergency spare wheel R 18 is 420 kPa
(4.2 bar).
Always check the inflation pressure of tyres when cold. Do not reduce the higher
pressure of warm tyres. Adapt the inflation pressure of the tyres accordingly if
your vehicle is carrying a significantly higher payload.
Driving style
Fast cornering, sharp acceleration and braking (squealing tyres) increase wear-
and-tear on your tyres.
Balancing wheels
The wheels of a new vehicle are balanced. There are a wide range of influences
when driving which may result in an imbalance and which makes themselves felt
through vibration in the steering.
You should have the wheels rebalanced since any imbalance increases wear-and-
tear on the steering, the suspension and tyres. A wheel must also be rebalanced
when a new tyre is fitted and each time a tyre is repaired.
Wheel alignment errors
Incorrect wheel alignment at the front and rear will not only increase wear-and-
tear on the tyres but will also has an adverse effect on vehicle safety. Contact
your specialist garage if you notice any unusual tyre wear. WARNING
● If the inflation pressure is too low, the tyre must perform a higher rolling
resistance. At higher speeds the tyre will warm up as a result of this. This can
result in tread separation and even a tyre blowout.
● Immediately replace the damaged rims or tyres.
● Tyres which are 6 years old or more should only be fitted in exceptional ca-
ses and when adopting an appropriately cautious style of driving. For the sake of the environment
Tyres which are insufficiently inflated increase your fuel consumption. Wear indicators
Fig. 158 Tyre tread with wear indicators
The base of the tread of the original tyres has wear indicators 1.6 mm high, instal-
led at right angles to the direction of travel. These wear indicators are located at 6
- 8 points depending on the make and are evenly spaced around the circumfer-
ence of the tyre ⇒ fig. 158 . Markings on the walls of the tyres through the letters
“TWI”, triangular symbols or other symbols identify the position of the wear indi-
cators.
A remaining tread of just 1.6 mm, measured in the grooves of the tread next to the
wear indicators, means that your tyres have reached their legally permissible mini-
mum tread depth. WARNING
● You must have your tyres replaced with new ones at the latest when the
wear indicators have been worn down. The legally permissible minimum tread
depth should be observed.
● Worn tyres do not provide the necessary adhesion to the road surface at
high speeds on wet roads. One could experience “
aquaplaning” (uncontrolled
movements of the vehicle - “swimming” on a wet road surface). 193
