Adding engine oil
H
Environmental note
When adding oil, take care not to spill any. If
oil enters the soil or waterways, it is harmful
to the environment.
! Use only engine oils and oil filters that
have been approved for vehicles equipped
with a service system. A list of the engine
oils and oil filters tested and approved in
accordance with the Mercedes-Benz
Specifications for Service Products can be
obtained from any authorized Mercedes-
Benz Center.
Damage to
the engine or exhaust system is
caused by the following:
R using engine oils and oil filters which
have not been specifically approved for
the service system.
R replacing the engine oil or oil filter after
the replacement interval required by the
service system has elapsed
R using engine oil additives. Example: engine oil cap Engine oil cap (G 55 AMG)
X
Turn cap : counterclockwise
and remove
it.
X Add the amount of oil required.
Observe the specifications in the on-board
computer when

doing so or fill carefully to the
maximum mark on the oil dipstick.
i The difference in quantity between the
MIN mark and the MAX mark on the
dipstick is approximately 2.1 US qts. (2 l).
! Do not add too much oil. If the oil level is
above the "max" mark on the dipstick, too
much oil has been added. This can lead to
damage to the engine or the catalytic
converter. Have excess oil siphoned off.
For further information on engine oil, see
(Y page 275).
X Replace cap : on the filler neck and
tighten clockwise.
Ensure that the cap locks into place
securely. Checking and adding other service
products
Coolant level Only check the coolant level when the vehicle
is on

a level surface and the engine has cooled
down. Engine compartment

Maintenance and care Z

If there is no premium-grade unleaded
gasoline available and regular-grade
unleaded gasoline may be used; please
observe the following precautions:
R
only fill the fuel tank to half full with
regular-grade unleaded gasoline and fill
the rest with premium-grade unleaded
gasoline as soon as possible.
R do not drive at the maximum speed.
R avoid sudden acceleration.
R if the
vehicle is carrying a light load, e.g.
two passengers without luggage, do not
allow the engine to rev above
3,000 rpm.
R if the vehicle is fully loaded or is being
operated in mountainous terrain, do not
depress the accelerator pedal further
than Ô of the pedal travel.
Fuel requirements Use only premium-grade unleaded gasoline.
The octane number should be at least 91.
Details can be found on the gas pump. The
octane number is the average value of the
Research Octane Number (RON) and the
Motor Octane Number (MON): (RON +
MON) / 2, also known as knock resistance.
Reformulated Gasoline (RFG) and/or
unleaded
gasoline

with additives can be used
if the concentration of the additives in the fuel
does not exceed 10%, e.g.:
R Ethanol
R TAME
R ETBE
R IPA
R TBA
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
containing
additives

that prevent the build-up
of carbon deposits.
If you use fuels without these additives for an
extended 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 problems, e.g.:
R longer engine warm-up phase
R uneven idle
R engine noise
R misfiring
R loss of power
In areas where carbon deposits can build up,
because of the lack of availability of gasoline
with the corresponding additives, Mercedes-
Benz recommends the use of additives that
have been approved for Mercedes-Benz
vehicles.
Consult an authorized Mercedes-Benz Center
or go to the Internet site
http://bevo.mercedes-benz.com for a list
of approved products. Comply with 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 to or malfunctions of the fuel
system may otherwise occur. 274

Engine oil
Please bear the following in mind 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.
For a list of approved engine oils and oil filters,
consult an authorized Mercedes-Benz Center
or go to the Internet site
http://bevo.mercedes-benz.com (USA
only).
! 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. You could
otherwise cause engine damage or damage
to the exhaust gas aftertreatment.
Follow the instructions in the service
interval display regarding the oil change.
Otherwise, you may damage the engine and
the exhaust gas aftertreatment.
The table shows which engine oils have been
approved for your vehicle. Model Engine
model MB
Approval
G 550 273 229.5
G 55 AMG 113 229.5
i
MB approval is indicated on the oil
containers.
Additives !
Do not

use any additives in the engine oil.
This could damage the engine.
Engine oil viscosity Viscosity describes the flow characteristics
of
a

fluid. If an engine oil has a high viscosity, this means that it is thick; a low viscosity
means that it is thin.
Select an engine oil with an SAE (viscosity)
classification suitable for the prevailing
outside temperatures. The following table
shows the correct SAE classification to be
used.
The

low-temperature characteristics of
engine oils can deteriorate significantly, e.g.
as a result of aging, soot and fuel deposits. It
is therefore strongly recommended that you
carry out regular oil changes using an
approved engine oil with the appropriate SAE
classification. Refrigerant of the air-conditioning
system
The air-conditioning system is filled with
R134a (HFC) refrigerant and a special PAG
lubricant.
! Never use refrigerant R 12 (CFC) or
mineral lubricants. Otherwise, you could
damage the air-conditioning system. Brake fluid
G
WARNING
The brake fluid constantly absorbs moisture
from the air; this lowers its boiling point.
If the

boiling point of the brake fluid is too low,
vapor pockets may form in the brake system
when the brakes are applied hard (e.g. when
driving downhill). This would impair braking
efficiency. Service products and capacities
