d-diesel engine
(outside EU)
ASTM D975 1-D and 2-D

ADVICE
Synthetic fuels (XTL, E-Fuels) according to EN 15940, are officially approved for all
engine types.
Not approved fuels in general
•
Fuel with a sulphur content exceeding 0.005% sulphur (50 ppm)
•
Marine diesel fuel
•
Aviation turbine fuel
•
Heating oils
•
Fatty acid methyl ester fuels according to DIN EN 14214 (often referred to by the
abbreviation FAME or also B100 (bio-diesel fuel)).
ATTENTION
Hazard of severe engine damages
Use only sulphur-free diesel fuel that conforms to the listed standards! Non-permitted
fuel types cause irreversible damage to the diesel engine and the exhaust gas treat-
ment system and significantly reduce the expected service life. Do not add petrol to
vehicles with diesel engines. Even small amounts of petrol can damage the fuel sys-
tem and diesel engine.
Water content
The maximum permissible water content in diesel fuel is 200 mg/kg.
Storage duration
Diesel fuel can decompose. If the maximum storage period of 90 days is exceeded,
check the fuel quality.
Diesel fuel at low temperatures
The flow capacity of the diesel fuel may be insufficient at low outside temperatures. In
order to avoid any operational problems, there are types of diesel fuel with better flow
properties which can be used during the winter months. Winter types of diesel fuel can
be used safely in the Federal Republic of Germany and other Central European coun-
tries at outside temperatures of up to -22 °C. Under normal conditions, in most coun-
tries, winter diesel fuel can be used without problems at the usual outside tempera-
tures.
