Brake fluid
Premium unleaded gasoline
Fuel requirements
During vehicle operation, the boiling point
of the brake fluid is continuously reduced
through the absorption of moisture from
the atmosphere. Under extremely strenu-
ous operating conditions, this moisture
content can lead to the formation of bub-
bles in the system, thus reducing the sys-
tem’s efficiency.
Use only premium unleaded fuel:
!
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
The octane number (posted at the
pump) must be 91 min. It is an average
of both the Research (R) octane num-
ber and the Motor (M) octane number:
(R+M)/2). This is also known as the
ANTI-KNOCK INDEX.
ț
Have the fuel tank only partially
filled with unleaded regular and fill
up with premium unleaded as soon
as possible.
Unleaded gasoline containing oxygenates
such as Ethanol, IPA, IBA and TBA can be
used provided the ratio of any one of these
oxygenates to gasoline does not exceed
10%; MTBE must not exceed 15%.
Therefore, the brake fluid must be re-
placed every two years, preferably in the
spring.
ț
ț
Avoid full throttle driving and abrupt
acceleration.
Only brake fluid approved by
Mercedes-Benz is recommended. Your au-
thorized Mercedes-Benz Center will pro-
vide you with additional information.
The ratio of Methanol to gasoline must not
exceed 3% plus additional co-solvents.
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.
Using mixtures of Ethanol and Methanol is
not allowed. Gasohol, which contains
10%
can be used.
Ethanol and 90% unleaded gasoline,
ț
Do not exceed 2/3 of maximum
accelerator pedal position if the ve-
hicle is fully loaded or operating in
mountainous terrain.
These blends must also meet all other fuel
requirements, such as resistance to spark
knock, boiling range, vapor pressure, etc.
