Fuel tank, l
including fuel reserve
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.
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.
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!
