Operation in winter conditions
In winter, the use of summer types of diesel fuel is not recommended.
At temperatures below 0°C, the separation of paraffin components occurs, it thickens and adversely affects the operation of the engine.
Therefore, in winter conditions, frost-resistant grades of diesel fuel with characteristics corresponding to the air temperature in winter in a given climatic zone should be used. In extreme cases, you can use both winter and summer varieties during this period, but you will need to dilute them with regular leaded or unleaded gasoline (just not super brand). Due to the fact that in this case there is a decrease in engine power, it is necessary to adhere to the following mixing proportions (maximum - 30%):
The fuel mixture ratio table has been calculated taking into account the operating conditions of the car in Germany.
For safety reasons, mixing must be carried out in the fuel tank, while gasoline is poured first.
It is advisable to do this in a timely manner, while the diesel fuel has not yet thickened.
If it has already thickened and the engine does not start, place the car for a while in a heated garage or room.
Mixing diesel fuel with any other additives is not recommended.
Recommendations for refueling with another type of fuel
Refueling with normal gasoline instead of Super-98 brand
It is allowed to operate the engine on this fuel, but only in exceptional cases, and then - the octane number of gasoline should not be lower than 91. In this case, the engine should only work at medium speeds and with a minimum load.
Sudden full throttle load and high RPM can damage the engine. At the first opportunity, immediately replace the fuel with the required grade of Super-95 or 98.
Super 95 unleaded gasoline instead of leaded gasoline
As an exception, short-term operation of the engine on this brand of fuel is also allowed.
At the same time, as in the previous section, heavy loads on it should be avoided due to the lower detonation properties of this gasoline.
For longer operation - appropriate adjustment of the engine is necessary.
Leaded gasoline instead of unleaded
Use of leaded gasoline is excluded in the presence of catalytic converters May damage the exhaust gas treatment system.
If this happens - the entire fuel system must be cleared of this fuel. It is best to clean at a service station.
Gasoline instead of diesel fuel
The engine can be operated on mixed fuel, but with a concentration of not more than 30%. If, by negligence, a larger amount of gasoline or Super brand gasoline is poured into the diesel fuel tank, the fuel mixture will have to be drained and the entire power system cleaned.
Diesel fuel instead of gasoline
Carburetor engines do not run on diesel fuel. Drain the fuel, clean the power system.
