Prescribed petrol 98/(95) RON / ROZ
We recommend using petrol 98 RON.
Optionally, petrol 95 RON can be used (slight power loss, a slightly increased
fuel consumption).
In an emergency petrol 91, 92 or 93 RON can be used (slight loss, a slightly
increased fuel consumption) »
CAUTION
The following instructions must be observed, otherwise there is a risk of en-
gine damage and damage to the exhaust system.
If gasoline is used which is lower than the prescribed octane number, then
■
continue driving at medium engine speeds and minimum engine load. Refuel
using petrol of the prescribed octane number as soon as possible.
Petrol with a lower Octane count than 91 should not even be used in an
■
emergency!
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.
CAUTION
Petrol additives (additives)
The unleaded petrol in accordance with the prescribed standards meets all
■
the conditions for a smooth running engine. Therefore, we recommend that
you do not add any fuel additives to the petrol - there is a risk of engine dam-
age or damage to the exhaust system.
The following additives and auxiliary products may not be used - there is a
■
risk of engine damage or damage to the exhaust system!
Additives with metal components (metallic additives), in particular with
■
manganese and iron content.
Fuels with metallic content (e.g. LRP - lead replacement petrol).
■
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 petrol of min. 95 RON, the use of petrol with a
■
higher octane number than 95 RON can increase the power and reduce fuel
consumption.
