Mercedes-Benz E-CLASS SEDAN 2023 Engine Oil User Manual 01

Engine damage caused by an incorrect oil filter, incorrect oil or additives

  • Do not use engine oils or oil filters other than those which meet the specifications necessary for the prescribed service intervals.
  • Do not alter the engine oil or oil filter to achieve longer change intervals than prescribed.
  • Do not use additives.
  • Have the engine oil changed after the prescribed intervals?

Mercedes-Benz recommends having the oil changed at a qualified specialist workshop. Only use engine oils approved for your vehicle by Mercedes-Benz

229.51, 229.52,

229.61, 229.71,


1) Recommended for the lowest possible fuel consumption (lowest SAE viscosity class in each case; observe possible restrictions of the approved SAE viscosity classes)

To achieve the lowest possible fuel consumption, it is recommended to use the engine oil specifications marked in the table with the lowest SAE viscosity class. Observe any possible restrictions of the approved SAE viscosity classes.

Engine oil filling capacity

Model                              Capacity
E 350 7.0 US qt (6.6 liters)
E 350 4MATIC 6.3 US qt (6.0 liters)
E 450 4MATIC 9.0 US qt (8.5 liters)

The specified filling capacity refers to an oil change with the oil filter.

Notes on brake fluid
Risk of an accident due to vapor pockets forming in the brake system The brake fluid constantly absorbs moisture from the air. This lowers the boiling point of the brake fluid. If the boiling point is too low, vapour pockets may form in the brake system when the brakes are applied hard. This causes the braking effect to be impaired.

  • Have the brake fluid renewed at the specified intervals?

Have the brake fluid regularly replaced at a qualified specialist workshop. Only use a brake fluid approved by Mercedes-Benz according to MB-Freigabe or MB-Approval 331.0.


Notes on coolant
Observe the notes on operating fluids.

Risk of fire and injury from antifreeze If antifreeze comes into contact with hot component parts in the engine compartment, it may ignite. Allow the engine to cool down before adding antifreeze.

  • Make sure that no antifreeze spills out next to the filler opening.
  • Thoroughly clean off any antifreeze from component parts before starting the vehicle.

NOTE Damage caused by incorrect coolant

  • Only use coolant that has been premixed with the required antifreeze protection.

Coolant information is available at the following locations:

NOTE Overheating at high outside temperatures If an inappropriate coolant is used, the cooling system is not sufficiently protected against overheating and corrosion at high outside temperatures.

  • Only use coolant approved for Mercedes-Benz.
  • Observe the instructions in the Mercedes-Benz Specifications for Operating Fluids 320.1.

Have the coolant regularly replaced at a qualified specialist workshop.

Proportion of antifreeze concentrate in the cooling system:

  • A minimum of 50% (antifreeze protection down to about -35°F (-37°C))
  • A maximum of 55% (antifreeze protection down to -49°F (-45°C))

Coolant filling capacity

Model Capacity
E 450 4MATIC 13.7 US qt (13.0 liters)
All other models 14.8 US qt (14.0 liters)

Notes on windshield washer fluid
Risk of fire and injury from windshield washer concentrate Windshield washer concentrate is highly flammable. It could ignite if it comes into contact with hot engine parts or the exhaust system.

  • Make sure that no windshield washer concentrate spills out next to the filler opening.

Damage to the exterior lighting due to unsuitable windshield washer fluid Unsuitable windshield washer fluid may damage the plastic surface of the exterior lighting.

  • Only use windshield washer fluid suitable for use on plastic surfaces, e.g. MB SummerFit or MB WinterFit.

NOTE Blocked spray nozzles caused by mixing windshield washer fluids

  • Do not mix MB Summer Fit and MB Winter Fit with other windshield washer fluids.

Do not use distilled or deionized water. Otherwise, the fill level sensor may be triggered erroneously.

Recommended windshield washer fluid:

  • Above freezing point: e.g. MB SummerFit
  • R Below freezing point: e.g. MB WinterFit

For the correct mixing ratio, refer to the information on the antifreeze container. Mix washing water with windshield washer fluid all year round.


Notes on refrigerant
Observe the notes on operating fluids. NOTE Damage due to incorrect refrigerant

The climate control system may be damaged if a non-approved refrigerant is used.

    • USA: use only R‑134a refrigerant.
    • Canada: use only R‑1234yf refrigerant.

NOTE Damage to the climate control system due to incorrect refrigerant compressor oil

  • Only use refrigerant compressor oil that has been approved by Mercedes-Benz.
  • Do not mix the approved refrigerant compressor oil with a different one.

Work on the climate control system may be carried out only at a qualified specialist workshop. All applicable regulations as well as SAE standard J639 must be adhered to. The information label for the climate control system regarding the refrigerant type and the refrigerant compressor oil (PAG oil) is located on the inside of the hood.
