Fuel Requirements
Use only Premium unleaded meeting
ASTM standard D 439:
The octane number (posted at the
pump) must be 91min. It is an average
of both, the Research (R) octane
number and the Motor (M) octane
number: [(R + M)/2]. This is also
known as ANTI-KNOCK INDEX.
Unleaded gasoline containing
oxygenates such as Ethanol, I PA, IBA
and TBA can be used provided the ratio
of any one of these oxygenates to
gasoline does not exceed 10%, MTBE
not to exceed 15%.
The ratio of Methanol to gasoline
must not exceed 3% plus additional
cosolvents.
Using mixtures of Ethanol and
Methanol is not allowed. Gasohol,
which contains 10% Ethanol and
90% unleaded gasoline, can be used.
These blends must also meet all other
fuel requirements such as resistance
to spark knock, boiling range, vapor
pressure etc..
Gasoline Additives
A major concern among engine
manufacturers is carbon build up
caused by gasoline. Mercedes-Benz
recommends to use only 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:
•
warm-up hesitation,
•
unstable idle,
•
knocking/pinging,
•
misfire,
•
power loss.
Do not blend other specific fuel
additives with fuel. They only result in
unnecessary cost, and may be harmful
to the 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.
