Do not use marine diesel oils, heating
oils, Aquazole and similar diesel-
water emulsions. Diesel fuels must
not be diluted with fuels for petrol
engines.
Fuel
Caution
Fuel for petrol engines
Use of fuel that does not comply to
EN 228 or E DIN 51626-1 or
equivalent can lead to deposits or
engine damage.
Only use unleaded fuel that complies
with European standard EN 228 or
E DIN 51626-1 or equivalent.
Fuel for liquid gas operation
The engine is capable of running with
fuel that contains up to 10% ethanol
(e.g. named E10).
Use fuel with the recommended
octane rating. The engine specific
requirements are given in the engine
data overview 3 227. A country
specific label at the fuel filler flap can
supersede the requirement.
Liquid gas is known as LPG
(Liquefied Petroleum Gas) or under
its French name GPL (Gaz de Pétrole
Liquéfié). LPG is also known as
Autogas.
Caution
Use of fuel with too low an octane
rating could lead to uncontrolled
combustion and engine damage.
LPG consists mainly of propane and
butane. The octane rating is between
105 and 115, depending on the
butane proportion. LPG is stored
liquid at around five to ten bar
pressure.
The boiling point depends on the
pressure and mixing ratio. At ambient
pressure, it is between -42 °C (pure
propane) and -0.5 °C (pure butane).
Fuel for diesel engines
Only use diesel fuel that complies
with EN 590.
Caution
In countries outside the European
Union use Euro-Diesel fuel with a
sulfur concentration below 50 ppm.
Do not use fuel or fuel additives
that contain metallic compounds
such as manganese-based
additives. This may cause engine
damage.
Caution
Use of fuel that does not comply to
EN 590 or similar can lead to
engine powerloss, increased wear
or engine damage.
Caution
The system works at an ambient
temperature of approx. -8 °C to
100 °C.
