4.4 Recommended fuel and lubricants
4.4.1 Fuel
Make sure the correct fuel is used.
The properties of light fuel oil that is only intended for heating do not meet the
requirements of modern diesel engines, and cannot be used as fuel.
The high pressure pump of the Common Rail system requires the fuel to have
sufficient lubricity, because it does not have separate oil lubrication. Adding oil to
diesel fuel is forbidden, because it causes carbon build-ups, and if oil is mixed
with even a small amount of water it clogs the filter.
Additionally, various fuel quality requirements imposed by taxation and seasonal
changes have to be taken into consideration.
4.4.1.1 Quality requirements for engine fuel
The fuel must conform to the EN 590:2009 standard.

IMPORTANT: To mix fuel with any admixing material or additives is not allowed.
4.4.1.2 Storing fuel
Fuel has to be stored in a dry and clean environment.
•
Arrange the conditions of storing and distributing fuel so that no water or
impurities can enter the storage tanks.
The storage tanks must be installed in a slanted position, so that water and
impurities are collected at the opposite end of the pump suction pipe. The
pump suction pipe must not reach the bottom of the tank.
• Drain the water periodically from the tank to prevent problems.
CAUTION: Do not refuel the tractor at the same time as the
storage tank is being refilled.
• Fill the tank with winter-quality fuel before the cold season.
4.4.1.3 Storing AdBlue/DEF
In order to guarantee the stability of AdBlue/DEF (as per DIN 70070 standard),
the following storage recommendations should be followed:
