Diesel Fuels - Mercedes-Benz 300 SDL turbo 126 D Owner's Manual

Diesel Fuels

Use only commercially available vehi­
cular diesel fuels No. 2 or No. 1
(ASTM D 975 No. 2-D or No. 1-D).
Caution!
The diesel engine is equipped with a
Trap Oxidizer. If you use non­
approved fuel additives, the Trap Oxi­
dizer could be damaged, resulting in
severe engine power loss and expen­
sive repairs, not covered under the
new vehicle warranty.
See your authorized MERCEDES-
BENZ dealer to find out if a list of
approved additives is available.
If diesel fuels are used with a sulphur
content exceeding 0.5 % by weight,
refer to the " Engine Oil Change and
Oil Filter Service" section. Marine die­
sel fuel, heating oil or the like must
not be used.
At very low temperatures the fluidity
of No. 2 diesel fuel may become insuf­
ficient due to paraffin separation.
To avoid malfunctions, No. 2 diesel
fuel of a lowered cloud point is mar­
keted during the cold season.
At temperatures below 0° C (32° F)
use winterized or No. 1 diesel fuel
only. If not available, a certain quantity
of kerosene may be added. Mixing
only to be done within the cars' fuel
tank. Kerosene has to be filled in
before the diesel fuel.
Engine power may drop according to
the proportion of kerosene. For this
reason, keep percentage of kerosene
added to the minimum necessitated
by the ambient temperature.
The following table can be used as a
reference, if adding of kerosene
becomes necessary. The mixing
ratios shown refer to the total mix­
ture. Even in extreme climatic condi­
tions, the maximum mixture ratio
should not exceed 50 % .
Ambient temperature
0° C to - 1 0 ° C ( + 32° F to +1 4° F)
below - 1 0 ° C ( + 14° F)
Adding of kerosene to No. 1 diesel
fuel is not recommended even at low
temperatures.
Warning!
Under no circumstances should
gasoline be added to diesel fuel.
This will destroy the Trap Oxidizer.
Always follow basic safety rules
when working with any combustible
material. Do not fill the fuel tank or
mix diesel fuel and kerosene when
smoking, near an open flame or
while the vehicle's engine is running.
An explosion or fire can result.
