Premium unleaded gasoline Gasoline additives
A major concern among engine manufac-
turers is carbon build-up caused by gaso-
line. Mercedes-Benz recommends only the
use of quality gasoline containing additives
that prevent the build-up of carbon depos-
its.
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
Warning! G
Gasoline is highly flammable and poisonous.
It burns violently and can cause serious inju-
ry. Whenever you are around gasoline, avoid
inhaling fumes and skin contact, extinguish
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
gasoline is not available and low octane
fuel is used, follow these precautions:
ț Have the fuel tank only partially
filled with unleaded regular and fill
up with premium unleaded as soon
as possible
ț Avoid full throttle driving and abrupt
acceleration
ț Do not exceed an engine speed of
3000 rpm if the vehicle is loaded
with a light load such as two per-
sons and no luggage
ț Do not exceed
2
/
3
of maximum
accelerator pedal position if the
vehicle is fully loaded or operating
in mountainous terrain
