Engine Oils; Brake Fluid; Air Conditioner Refrigerant - Mercedes-Benz 300 SD 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.

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.

Air Conditioner Refrigerant

Ozone-friendly HFC-134a refrigerant
and special 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.
