Selection of a Suitable Diesel Fuel
The quality of the fuel is very important for satisfactory engine performance, long engine service life and acceptable
exhaust emission levels. The engines can be operated with most diesel fuels sold worldwide. The properties and
limit values specified in Table 11 (fuels of comparable quality) ensure optimum engine performance.
In order to achieve optimum engine performance and satisfactory service life for the entire fuel and injection system,
the limit values for water and total contamination must be complied with in the engine tank for all approved fuel
qualities. Furthermore, it is advisable to integrate an additional filtering system in the fuel system.
Emission certification
The certification measurements for verifying observance of the statutory emission limits are carried
out with the respectively prescribed certification fuels.
Dispose of used fluids and lubricants i n accordance with local regulations.
Used oil must never be disposed of via t he fuel tank!
