Premium unleaded gasoline 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:
앫
Warm-up hesitation
앫
Unstable idle
앫
Knocking/pinging
앫
Misfire
앫
Power loss
Warning!
G
Gasoline is highly flammable and poisonous.
It burns violently and can cause serious per-
sonal injury.
Never allow sparks, flame or smoking mate-
rials near gasoline!
Turn off the engine before refueling
Whenever you are around gasoline, avoid in-
haling fumes and skin or clothing contact,
extinguish all smoking materials.
Direct skin contact with fuels and the inha-
lation of fuel vapors can be damaging to
your health.
!
To maintain the engine’s durability and per-
formance, premium unleaded gasoline must be
used. If premium unleaded is not available and
low octane fuel is used, follow these precau-
tions:
앫
Have the fuel tank only partially filled with
unleaded regular and fill up with premium
unleaded as soon as possible.
앫

ation.
앫
