Prem ium U nleaded G asoline
Caution!
To m aintain the e ng in e ’s durability
and perform ance, prem ium un
leaded gasoline m ust be used. If
premium unleaded is not available
and low octane fuel is used, follow
these precautions:
• have the fuel tank filled only
partially with unleaded regular
and fill up with prem ium un
leaded as soon as possible,
• avoid full throttle driving and
abrupt acceleration,
• do not exceed an engine speed
of 3000 rpm, if the vehicle is
loaded with a light load such as
two persons and no luggage,
• do not exceed 2/3 of m axim um
accelerator pedal position, if the
vehicle is fully loaded or ope ra t
ing in m ountainous terrain.
Fuel R equirem ents
Use only Prem ium unleaded
m eeting ASTM standard D 439:
The octane num ber (posted at the
pump) m ust be 91 min. It is an
average of both the Research (R)
octane num ber and the M otor (M)
octane number: [(R+M )/2]. T his is
also known as A N TI-KN O C K
INDEX.
U nleaded gasoline containing
oxygenates such as Ethanol, I PA,
I BA and TB A can be used provided
the ratio of any one of these
oxygenates to gasoline does not
exceed 10%, M TBE not to exceed
15%.
The ratio of M ethanol to gasoline
m ust not exceed 3% plus a ddi
tional cosolvents.
Using m ixtures of Ethanol and
M ethanol is not allowed. G asohol,
which contains 10% Ethanol and
90% unleaded gasoline, can be
used.
These blends m ust also m eet all
other fuel requirem ents such as
resistance to spark knock, boiling
range, vapor pressure etc..
G aso line A dditives
A m ajor concern am ong engine
m anufacturers is carbon build up
caused by gasoline. M ercedes-
Benz recom m ends the use of only
quality gasoline containing
additives th at prevent the build up
of carbon deposits.
A fter an extended period of using
fuels w ithout such additives,
carbon deposits can build up
e specially on the intake valves and
in the com bustion area, leading to
engine perform ance problem s such
as:
• w arm -up hesitation,
• unstable idle,
• knocking/pinging,
• misfire,
• pow er loss.
Do not blend other specific fuel
additives with fuel. T hey only result
in unnecessary cost, and may be
harm ful to the engine operation.
D am age or m alfunctions resulting
from poor fuel quality or from blen
ding specific fuel additives are not
covered by the M ercedes-B enz
