Technical data 345
Only refuel with fuel, that has at least the octane
number specified in the information table in the
fuel filler flap ( page 138). This may reduce
→
engine output and increase fuel consumption.
If you want maximum engine output: only
refuel with unleaded premium grade gasoline
with an octane number of at least 95 RON.
Never refuel using gasoline with a lower RON.
* NOTE Premature wear caused by unlea‐
ded regular gasoline
Unleaded regular gasoline can cause the
engine to wear more quickly and impair lon‐
gevity and performance.
If unleaded premium grade gasoline is
unavailable and you have to refuel using
unleaded regular gasoline:
Only fill the fuel tank to half full with
#
unleaded regular gasoline and refill as
soon as possible with unleaded pre‐
mium grade gasoline.
Do not drive at the maximum speed.
