Fuel for petrol engines

Only use unleaded fuel that complies
with European standard EN 228 or
E DIN 51626-1 or equivalent.
Your engine is capable of running
with E10 fuel that fulfills these
standards. E10 fuel contains up to
10 % bioethanol.
Use fuel with the recommended
octane rating 3 202. Use of fuel with
too low an octane rating can reduce
engine power and torque and slightly
increases fuel consumption.
Caution
Do not use fuel or fuel additives
that contain metallic compounds
such as manganese-based
additives. This may cause engine
damage.
Caution
Use of fuel that does not comply to
EN 228 or E DIN 51626-1 or
equivalent can lead to deposits or
engine damage and may affect
your warranty.
Caution
Use of fuel with too low an octane
rating could lead to uncontrolled
combustion and engine damage.
Note
Use unleaded Premium fuel only for
the following countries:
Armenia, Azerbaijan, Belarus,
Moldova.
Fuel for ethanol adapted
engines (E85)
If access to E85 is limited then fuel
with a different proportion of ethanol
or normal RON 95 can be used for
refuelling. The engine's control
management system is adjusted
automatically according to the
amount of ethanol in the fuel.
E85 fuel must fulfil the CWA 15293 or
SS 155480 standard.
When the temperature is about
-10 °C or lower a greater proportion of
petrol should be used. E85 in
combination with low temperatures
could lead to the car being more
difficult to start. A slightly higher
proportion of petrol improves the cold
start properties considerably.
During the engine's warm-up phase
(below +50 °C) engine torque is
limited when driving with a proportion
of ethanol.
Ethanol contains less energy per litre
than petrol, which is why fuel
consumption increases when driving
on E85 compared with petrol. A
consequence of this is that a tank of
E85 covers fewer kilometres than a
tank of petrol.
