WARNING
Avoid contact with fuels.
It is hazardous to your health if your skin
comes into direct contact with fuels or you
breathe in fuel vapours.
! If you are using drums or canisters to
refuel the engine/vehicle/equipment, you
should filter the fuel before filling.
This prevents malfunctions in the fuel sys-
tem caused by contaminated fuel.
The following fuel types are not permitted:
R
marine diesel fuel
R
aviation turbine fuel
R
heating oils
! Only refuel with commercially available
diesel vehicle fuel that complies with the
European standard EN 590.
EN 590 describes a sulphur-free fuel with a
maximum sulphur content of 10 ppm. How-
ever, it is also permitted to operate engines
with BlueTec
®
exhaust gas aftertreatment
with up to 50 ppm.
For engines without BlueTec
®
exhaust gas
aftertreatment, the maintenance intervals
must be reduced when operating with
higher sulphur contents. For details on this,
see the table below. Even if the mainte-
nance intervals are reduced, operation with
higher sulphur contents will lead to
increased engine wear, especially on the
fuel injectors.
When necessary, use only approved fuel
additives.
There is otherwise a risk of impaired engine
performance or engine and catalytic con-
verter damage. The use of appropriate fuel
additives is your responsibility.
Sulphur content in
diesel fuel
Interval for chang-
ing engine oil and
filter
Up to 0.3% by weight
(3000 ppm) 100%
From 0.3% by weight
(3000 ppm) to 0.8%
by weight
(8000 ppm) 50%
Over 0.8% by weight
(8000 ppm) 30%
! Fuel grade in accordance with EN 590 is
prescribed as mandatory for engines with
BlueTec
®
exhaust gas aftertreatment. If
diesel fuel which does not comply with EN
590 is used, it can damage the exhaust
system.
Fuel grade
Information about current country-specific
fuel sulphur contents can be obtained from
any Mercedes-Benz or MTU Service Centre
(
Y
page 11).
i Certain countries have diesel fuel with
varying sulphur content. Diesel fuel with
low sulphur content is sold in certain coun-
tries under the name "Euro diesel".
Fuel sulphur content
You can find a table of fuel sulphur contents
in specific countries in the Mercedes-Benz
Specifications for Service Products, Sheets
136.1 and 136.2 at http://bevo.mercedes-
benz.com.
The maintenance intervals for engine oil and
filter replacement must be adapted depend-
ing on the fuel grade used. The higher the sul-
phur content in diesel fuel, the shorter the
maintenance intervals for engine oil and filter
replacement. Observe the notes in the Main-
tenance Booklet.
