Engine Oils - Mercedes-Benz Light Truck ML 320 Operator's Manual

Engine Oils

Engine oils are specifically tested for
their suitability in our engines.
Therefore, use only engine oils
recommended by Mercedes-Benz.
Information on recommended brands is
available at your authorized Mercedes-
Benz dealer.
Please follow Service Booklet
recommendations for scheduled oil
changes. Failure to do so could result in
engine damage not covered by the
Mercedes-Benz Limited Warranty.
Engine Oil Additives
Do not blend oil additives with engine
oil. They may be harmful to the engine
operation.
Damage or malfunctions resulting from
blending oil additives are not covered
by the Mercedes-Benz Limited
Warranty.
Air Conditioner Refrigerant
R-134a (HFC) refrigerant and special
PAG lubricating oil is used in the air
conditioner system.
Never use R-12 (CFC) or mineral-
based lubricating oil, otherwise damage
to the system will occur.
Brake Fluid
During vehicle operation, the boiling
point of the brake fluid is continuously
reduced through the absorption of
moisture from the atmosphere. Under
extremely hard operating conditions,
this moisture content can lead to the
formation of bubbles in the system thus
reducing the system's efficiency.
The brake fluid must therefore be
replaced every two years, preferably
in the spring.
It is recommended to use only brake
fluid approved by Mercedes-Benz.
Your authorized Mercedes-Benz dealer
will provide you with additional
information.
