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
injury. Whenever you are around gasoline,
avoid inhaling fumes and skin contact, extin-
guish all smoking materials. Never allow
sparks, flame or smoking materials near
gasoline!
!
To maintain the engine’s durability and
performance, premium unleaded gaso-
line must be used. If premium unleaded
is not available and low octane fuel is
used, follow these precautions:
앫
Have the fuel tank only partially
filled with unleaded regular and fill
up with premium unleaded as soon
as possible.
앫
Avoid full throttle driving and abrupt
acceleration.
앫
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.
앫
Do not exceed
2
/
3
of maximum
accelerator pedal position if the
vehicle is fully loaded or operating
in mountainous terrain.
