Ethanol E85 - Skoda Octavia Owner's Manual

Fuels with metallic content may not be used. There is a risk of causing consider-
■
able damage to parts of the engine or exhaust system!
The use of unsuitable fuel additives can cause considerable damage to parts of
■
the engine or the exhaust system.

Ethanol E85

ä
First read and observe the introductory information and safety warn-
ings on page 161.
Only valid for vehicles with the 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 ve-
hicle or high engine speeds and not at full throttle. During this process decrease
the idling speed.
Operation in winter
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. 133.

Under -25 ℃
If an engine preheating is not possible at outside temperatures below -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.
CAUTION
Just filling the tank once with diesel fuel that does not comply with the stand-
■
ard, can cause severe damage to parts of the engine, the fuel and exhaust sys-
tem!
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
■
The use of engine preheating at temperatures below -10 °C has a positive effect
■
on the fuel consumption and thus on the environment.
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.
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.
The interval of 15 000 km applies for the oil change.

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

the luggage compartment.
Duration of engine preheating
We recommend up to 1 hour
