 | Separate characteristics are resulted also in the text of the Head and in case of compulsion of their performance are shown in bold |
|
Fuel |
Fuel tank, l |
Capacity | 62 |
including fuel reserve | 8 |
Petrol models |
Unleaded gasoline is not worse AI-95 / A-85, may temporarily use unleaded gasoline is not worse AI-91 / A-82.5. The power of the engine to decrease slightly, with an increase in fuel consumption |
Do not use fuel additives. They can lead to increased wear or damage to the engine. |
Diesel models |
Summer and winter diesel fuel | Number 2 or number 1 to ASTM D975 |
Do not use marine (Marine Diesel Fuel), boilers, etc. diesel fuel. |
When using diesel fuel with a sulfur content exceeding 0.5%, make replacement of motor oil every 10,000 km. |
Winter fuel, provides normal operation down to -20 ?� C. |
Through preheating enabled when the heating system of the car, the car in the winter diesel fuel can usually be operated without failure when the outdoor temperature down to -25 ?� C. |
Do not add gasoline to diesel fuel. |
In the case of summer diesel fuel, as well as the outdoor temperature is below -15 ?� C should be added to the fuel specific, depending on the amount of outside air temperature flow improver or kerosene. |
Flow improver may also be used in combination with kerosene. |
Certificate means you can get to the service station Mercedes-Benz. |
The proportion of additives taking into account ambient air temperature should be minimal. |
Share kerosene mixture should not exceed 50%. |
The additive is mixed to the diesel fuel to the loss of flow properties of diesel fuel as a result of paraffin separation. Problems due to the evolution of paraffin can be eliminated only heating the entire power system. |
Mixing diesel and kerosene held only in the fuel tank. For this first pour kerosene tank, and then add the diesel fuel. |
After this, the motor must work for a while in order to blend dispersed throughout the system power. |
Flammable! |
Additives kerosene lead to lower the flash point of the diesel fuel. Because of this danger when handling fuel mixture increases. Observe the relevant safety regulations! |
