546 Technical dataFuels, coolants, lubricantsEngine oils
Engine oils are specifically tested for their 
suitability in our engines and durability for 
our service intervals. Therefore, only use 
approved engine oils and oil filters re-
quired for vehicles with Maintenance 
System (U.S. vehicles) or FSS PLUS (Cana-
da vehicles). For a listing of approved en-
gine oils and oil filters, refer to the Factory 
Approved Service Products pamphlet, or 
contact an authorized Mercedes-Benz 
Light Truck Center.
Engine oil additives
Do not blend oil additives with engine oil. 
They may damage the engine.
Damage or malfunctions resulting from 
blending oil additives are not covered by 
the Mercedes-Benz Limited Warranty.Air conditioning refrigerant
R-134a (HFC) refrigerant and special PAG 
lubricating oil are used in the air condition-
ing system.
Never use R-12 (CFC) or mineral-based lu-
bricating oil. Otherwise damage to the 
system will occur.
Brake fluid
Only brake fluid approved by 
Mercedes-Benz is recommended. Your 
authorized Mercedes-Benz Light Truck 
Center will provide you with additional in-
formation.
!
Using engine oils and oil filters of 
specification other than those expressly 
required for the Maintenance System 
(U.S. vehicles) or FSS PLUS (Canada vehicles), 
or changing of oil and oil filter at change intervals 
longer than those called for by the Maintenance 
System (U.S. vehicles) or FSS PLUS (Canada ve-
hicles) will result in engine or emission control 
system damage not covered by the 
Mercedes-Benz Limited Warranty.Please follow Maintenance System 
(U.S. vehicles) or FSS PLUS (Canada vehicles) 
recommendations for scheduled oil changes. 
Failure to do so could result in engine or 
emission control system damage not covered by 
the Mercedes-Benz Limited Warranty.
Warning!
G
During vehicle operation, the boiling point of 
the brake fluid is continuously reduced 
through the absorption of moisture from the 
atmosphere. Under extremely strenuous op-
erating conditions, this moisture content 
can lead to the formation of bubbles in the 
system, thus reducing the system’s efficien-
cy.
Therefore, the brake fluid must be replaced 
regularly. Refer to your vehicle’s 
Maintenance Booklet for replacement inter-
val.

547 Technical data
Fuels, coolants, lubricants
Premium unleaded gasoline (gasoline engine)
Gasoline additives (gasoline engine)
A major concern among engine manufac-
turers is carbon build-up caused by gaso-
line. Mercedes-Benz recommends only the 
use of quality gasoline containing additives 
that prevent the build-up of carbon depos-
its.
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
Warning!
G
Gasoline is highly flammable and poisonous. 
It burns violently and can cause serious 
injury.
Never allow sparks, flame or smoking mate-
rials near gasoline!
Turn off the engine before refueling.
Whenever you are around gasoline, avoid in-
haling fumes and skin or clothing contact, 
extinguish all smoking materials.
Direct skin contact with fuels and the inha-
lation of fuel vapors can damage your 
health.
!
To maintain the engine’s durability and per-
formance, premium unleaded gasoline must be 
used. If premium unleaded is not available and 
low octane fuel is used, follow these precau-
tions:
Have the fuel tank only partially filled with 
unleaded regular and fill up with premium 
unleaded as soon as possible.
Avoid full throttle driving and abrupt acceler-
ation.
Do not exceed an engine speed of 3000 rpm 
if the vehicle is loaded with a light load such 
as two persons and no luggage.
Do not exceed 
2/3 of maximum accelerator 
pedal position if the vehicle is fully loaded or 
operating in mountainous terrain.

548 Technical dataFuels, coolants, lubricantsIn areas where carbon deposits may be 
encountered due to lack of availability of 
gasolines which contain these additives, 
Mercedes-Benz recommends the use of 
additives approved by us for use on 
Mercedes-Benz vehicles. Refer to Factory 
Approved Service Products pamphlet for a 
listing of approved product(s). Follow 
directions on product label.
Do not blend other fuel additives with fuel. 
This only results in unnecessary costs and 
may be harmful to the engine operation.
Damage or malfunction resulting from 
poor fuel quality or from blending addition-
al fuel additives other than those tested 
and approved by us for use on 
Mercedes-Benz vehicles listed in the 
Factory Approved Service Products 
pamphlet are not covered by the 
Mercedes-Benz Limited Warranty.
Fuel requirements
Gasoline engine
Only use premium unleaded fuel.
The octane number (posted at the 
pump) must be 91 min. It is an average 
of both the Research (R) octane num-
ber and the Motor (M) octane number: 
(R+M) /2). This is also known as the 
ANTI-KNOCK INDEX.
Unleaded gasoline containing oxygenates 
such as ethanol, 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 
diesel fuels No. 2 or No. 1 (ASTM D975 No. 
2-D or No. 1-D).
To prevent malfunctions, diesel fuel with 
improved cold flow characteristics is of-
fered in the winter months. Check with 
your fuel retailer.
!
Do not fill the tank with gasoline. Do not 
blend diesel fuel with gasoline or kerosine. The 
fuel system and engine will otherwise be dam-
aged, which is not covered by the 
Mercedes-Benz Limited Warranty.

Fuels, coolants, lubricants
Coolants
The engine coolant is a mixture of water 
and anticorrosion/antifreeze, which 
provides:
Corrosion protection
Freeze protection
Boiling protection (by increasing the 
boiling point)
The cooling system was filled at the factory 
with a coolant providing freeze protection 
to approximately -35°F (-37°C) and corro-
sion protection.If the antifreeze mixture is effective to 
-22°F (-30°C), the boiling point of the cool-
ant in the pressurized cooling system is 
reached at approximately 266°F (130°C).
The coolant solution must be used year 
round to provide the necessary corrosion 
protection and increase boil-over protec-
tion. Refer to Maintenance Booklet for 
replacement interval.
Coolant system design and coolant used 
determine the replacement interval. The 
replacement interval published in the 
Maintenance booklet is only applicable if 
MB 325.0 anticorrosion/antifreeze solu-
tion or other Mercedes-Benz approved 
products of equal specification (see 
Factory Approved Service Products 
pamphlet) are used to renew the coolant 
concentration or bring it back up to the 
proper level.To provide important corrosion protection, 
the solution must be at least 45% anticor-
rosion/antifreeze (equivalent to freeze 
protection to approx. - 22°F [-30°C]). If 
you use a solution that is more than 55% 
anticorrosion/antifreeze (freeze protec-
tion to approx. - 49°F [-45°C]), the engine 
temperature will increase due to the lower 
heat transfer capability of the solution. 
Therefore, do not use more than this 
amount of anticorrosion/antifreeze.
If the coolant level is low, water and 
MB 325.0 anticorrosion/antifreeze should 
be used to bring it up to the proper level 
(have cooling system checked for signs of 
leakage). Please make sure the mixture is 
in accordance with label instructions.
The water in the cooling system must meet 
minimum requirements, which are usually 
satisfied by normal drinking water. If you 
are not sure about the water quality, con-
sult an authorized Mercedes-Benz Light 
Truck Center.
!
Add premixed coolant solution only. Adding 
water and MB 325.0 Anticorrosion/Antifreeze 
separately from each other, could cause engine 
damage not covered by the 
Mercedes-Benz Limited Warranty.
