Recommended greasings and liquids

Do not allow children to operational materials, - at their hit in an organism of the child immediately address to the doctor!

Apply materials exclusively recommended by the Mercedes-Benz company, - they are listed in special Instructions of firm. On this matter you can receive the reference on HUNDRED. Application of the allowed operational materials is a component of guarantee certificates.

Type and working liquids


Petrol models Unleaded gasoline is not worse AI95/A85. Short-term use of unleaded gasoline not worse AI91/A82.5 (the capacity developed by the engine decreases a little, fuel consumption grows) is allowed.

Application of additives to fuel is fraught premature to wear and damages of internal components of the engine!

Diesel models

Summer and winter diesel fuel

Do not apply ship, boiler, etc. diesel fuels!

When using diesel fuel with raised (more than 0.5 %) the content of sulfur make replacement of impellent oil through each 7500 km of run from above.

Winter fuel provides normal operability of the engine at temperatures to - 20°С.

Thanks to preliminary heating of fuel at the included system of heating of salon trouble-free functioning of the engine is guaranteed at temperatures of external air to - 25°С.

Do not add gasoline to diesel fuel!

In case of application of summer diesel fuel, and also at temperatures of external air is lower - 15°С to fuel it is necessary to add certain, depending on temperature of external air quantity of means for fluidity or kerosene improvement.

Means for improvement of fluidity can be used also in a combination to kerosene.

The certificate of the allowed means for improvement of fluidity can be received on any HUNDRED Mercedes-Benzs.

The share of the maintenance of an additive taking into account temperature of external air should be minimum.

The share of kerosene in a mix should make no more than 50 %.

The additive should be added to fuel during filling before there was its zagusteniye to paraffin allocation. Owing to allocation of paraffin it is possible to eliminate malfunctions only with a way of heating of all power supply system.
Mixing of diesel fuel with kerosene carry out only in a fuel tank, - at first in a tank kerosene is filled in, then diesel fuel is added. In summary it is necessary to allow to the engine to work for some time for mix distribution on all path of a power supply system.

Additives of kerosene lead to decrease in a point of ignition of diesel fuel owing to what fire danger of a mix increases! Observe the corresponding safety regulations!
