Fuel requirements
Gasoline engine
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.
Reformulated gasolines (RFG) and/or
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%.
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.
Diesel engine
Only use commercially available vehicular
ULTRA-LOW SULFUR HIGHWAY DIESEL FUEL
(15 ppm SULFUR MAXIMUM). Failure to use
ULTRA-LOW SULFUR HIGHWAY DIESEL FUEL
can severely damage the vehicle’s exhaust
after-treatment device.
To prevent malfunctions, diesel fuel with
improved cold flow characteristics is offered
in the winter months. Check with your fuel
retailer.
!
Do not fill the tank with gasoline. Do not
blend diesel fuel with gasoline or kerosene.
The fuel system and engine will otherwise
be damaged, which is not covered by the
Mercedes-Benz Limited Warranty.
B5 Biodiesel
Mercedes-Benz approves the use of B5
biodiesel (standard diesel with a maximum of
up to 5% biodiesel content) in all Common Rail
Injection (CDI) and BlueTEC diesel engines.
Diesel fuels containing a higher percentage of
biodiesel content will cause damage to your
engine and are not approved.
As biodiesel can be refined from a variety of
raw materials resulting in widely varying
properties, the only approved biodiesel
content is one that meets ASTM D6751
specification. It must also have the necessary
oxidation stability (min. 6h, proved with
EN14112 method) to prevent damage to the
system from deposits and/or corrosion.
Please ask your service station for further
information. If the B5 biodiesel blend is not
sufficiently labeled to clearly indicate that it
meets the above standards, please do not use
it. The Mercedes-Benz Limited Warranty does
not cover damage caused by the use of fuels
not meeting Mercedes-Benz approved fuel
standards.
