Fuel requirements
Only use premium unleaded gasoline. The
octane number (posted at the pump) must be
91
min. It is an average of both the Research
Octane Number (RON) and the Motor Octane
Number (MON): (RON+MON)/2. This is also
known as the ANTI-KNOCK INDEX.

Gasoline is highly flammable and poisonous.
It burns violently and can cause serious
personal injury.
unleaded gasoline containing oxygenates
such as ethanol, TAME, ETBE, 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%.
Never allow sparks, flames or smoking
materials near gasoline!
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.
Turn off the engine before refueling.
Whenever you are around gasoline, avoid
inhaling fumes and any skin or clothing
contact. Extinguish all smoking materials.
Direct skin contact with fuels and the
inhalation of fuel vapors are damaging your
health.

To maintain the engine’s durability and
performance, premium unleaded gasoline
must be used.
If premium unleaded gasoline is not
available and low octane gasoline is used,

A major concern among engine
manufacturers is carbon build-up caused by
gasoline. Mercedes-Benz recommends only

with unleaded regular gasoline and fill up the use of quality gasoline containing
with premium unleaded gasoline as soon additives that prevent the build-up of carbon
as possible.
deposits.
RAvoid full throttle driving and abrupt
acceleration.
RDo not exceed an engine speed of
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:
3

light load such as two persons and no

In areas where carbon deposits may be
encountered due to lack of availability of
gasoline which contains these additives, the
