Gasoline additives
A major concern among engine
manufacturers is carbon build-up caused
by gasoline. Mercedes-Benz recommends
only the use of quality gasoline containing
additives that prevent the build up of
carbon deposits.
After an extended period of using fuels
without such additives, carbon deposits
can build up especially on the intake valves
and in the combustion area, leading to
engine performance problems such as:
ț Warm-up hesitation
ț Unstable idle
ț Knocking/pinging
ț Misfire
ț Power loss
Do not blend any specific fuel additives
with fuel. This only results in unnecessary
cost and may be harmful to engine
operation.
Damage or malfunctions resulting from
poor fuel quality or from blending specific
fuel additives are not covered by the
Mercedes-Benz Limited Warranty.
Flexible Fuel Vehicles
Flexible Fuel Vehicles are identified by a
label reading Premium gasoline or E85
only! on fuel filler flap.
These vehicles are designed to operate on
premium unleaded gasoline or Ethanol
fuel (E85), or on any mixture of these two.
Ethanol fuel (E85) is a mixture of
approximately 85% Ethanol and 15%
unleaded gasoline.
Switching fuels
For best performance and driveability it is
recommended to use either one or the
other fuel. A refueling pattern that
alternates between the two different fuels
should be avoided if possible.
Warning! G
Ethanol fuel (E85) and its fumes are highly
flammable, poisonous and burn easily. Etha-
nol fuel can cause serious injuries if ignited
or if you come into contact with it or inhale
fumes of it. Avoid inhalation of Ethanol
fumes and skin contact with Ethanol. Extin-
guish all open flames before fueling. Never
smoke or create sparks close to Ethanol.
