Systems of power supply and edition

The separated characteristics are provided also in the text of the head and in case of need its executions are chosen bold print.

Fuel grades

Petrol models

neetilirowannyj gasoline is not worse than AI95/A85. Short-term use of neetilirowannogo of gasoline is not allowed worse AI91/A82.5 (developed by the motor the power something which grows fuel costs falls).

Application of addition to fuel threateningly before time to sale and damages of internal components of the motor!

Diesel models

Summer and winter fuel of the diesel

Do not use the ship, kotelnoje, etc. the fuel diesel!

At the appendix of diesel fuel with at height (the bigger number of 0.5%) to the content of sulfur you make compensation of engine oil of each 7500 km of the movement from above.

Winter fuel guarantees normal operability of the motor at temperatures to 20 °S.

Thanks to preliminary heating of fuel at the made system of heating of salon trouble-free functioning of the garantirowano motor at temperatures of external air to 25 °S.

Do not add gasoline to diesel fuel!


In case of application of the summer combustible diesel, and also at temperatures of external air it is 15 °S to fuel below it is defined it is necessary to supplement quantity By means of for improvement of fluidity or kerosene depending on temperature of external air.

It is possible to use funds for improvement of fluidity also in a combination with kerosene.

On everyone Mercedes Benz it is possible to receive the certificate of the allowed funds for improvement of fluidity.

Participation of content of addition considering temperature of external air it has to be minimum.

Participation of kerosene in mix should not form 50% any more.

Addition has to be supplemented to fuel during gas station until until it did not happen sagustenije to office of paraffin. Only by means of heating of all system of power supply it is possible to delete defects owing to office of paraffin.

You carry out mixing of diesel fuel with kerosene only in the tank, - at first in the tank kerosene is filled in, then distopliwo is supplemented. At last it is necessary to resolve it is necessary for the motor that it worked during certain time for distribution of mix after all path of system of power supply.

Addition of kerosene leads to immersion of point of ignition of diesel fuel owing to whose the mix inflammability grows! Pay attention to the corresponding safety rules of work!
