For MTBE, the concentration should not

exceed 15%.

The concentration of methanol in gasoline

including other additives must not exceed 3%.

Using mixtures of methanol and ethanol is not

permitted. Gasohol, a mixture of 10% ethanol

and 90% unleaded gasoline can be used.

All of these mix fuels must fulfill the fuel

requirements, e.g.:

R

knock resistance

R

boiling point

R

vapor pressure

Additives in gasoline

One of the major problems in engine design

is the creation of carbon deposits during the

process of burning fuel. Mercedes-Benz

recommends that you use fuel brands that

have the additives which prevent the build up

of carbon deposits.

If you use fuels without these additives for a

longer period of time, there may be a build up

of carbon deposits, especially on the inlet

valves and in the combustion chamber.

This could lead to engine running problems,

e.g.:

R

warm-up hesitation

R

unstable idle

R

knocking/pinging

R

misfire

R

power loss

In areas where carbon deposits may be

encountered due to lack of availability of

gasoline which contains these additives,

Mercedes-Benz recommends the use of

additives approved for use in Mercedes-Benz

vehicles.

Consult an authorized Mercedes-Benz Center

or visit http://www.mbusa.com (USA only)

to view a list of approved products. Observe

the instructions for use on the product label.

Do not mix other fuel additives with fuel. This

causes unnecessary costs and could damage

the engine.

!

Do not refuel with low-grade fuel and do

not use fuel additives that are not tested

and approved for Mercedes-Benz vehicles.

Damage or malfunctions can result that are

Engine oil

Points to remember

The engine oils are matched to the

performance of Mercedes-Benz engines and

service intervals. For this reason, only use

engine oils and oil filters that are approved for

vehicles with a service system.

Contact an authorized Mercedes-Benz Center

or visit http://www.mbusa.com (USA only)

for a list of approved engine oils and oil filters.

!

Never use engine oil or an oil filter of a

specification other than is necessary to

fulfill the prescribed service intervals. Do

not change the engine oil or oil filter in

order to achieve longer replacement

intervals than those prescribed. Otherwise,

you may cause damage to the engine or

exhaust gas aftertreatment; this is not

covered by the Mercedes-Benz Limited

Warranty.

Follow the instructions in the service

interval display regarding the oil change.

Otherwise, you may damage the engine and

the exhaust gas aftertreatment.

Mercedes-Benz recommends MOBIL OIL.

The table shows which engines oil have been

approved for your vehicle.
