Diesel Fuel Additives in Vehicles Cer
tified fo r California Operation.
Beginning with 1985 models, Califor-
nia-Version Diesel Engine vehicles
are equipped with a Trap Oxidizer. If
you use non-approved fuel additives,
the Trap Oxidizer could be damaged,
resulting in severe engine power loss
and expensive 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.
Change engine oil in com pliance with
section "Engine Oil Change and Oil
Filter Service" if diesel fuels are used
whose sulphur content exceeds
0.5 % by weight. Marine diesel fuel,
heating oil or the like m ust not be
used.
At very low tem peratures the fluidity
of No. 2-D diesel fuel may become
insufficient due to paraffin separation.
To avoid m alfunctions, No. 2-D diesel
fuel of a lowered cloud point is
marketed during the cold season.
A t tem peratures 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 w ithin the c a rs' 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 o f kerosene
added to the minimum necessitated
by the ambient tem perature.
The following table can be used as a
reference, if adding of kerosene
becom es necessary. The mixing
ratios shown refer to the total
mixture. Even in extrem e clim atic
conditions, the maximum mixture
ratio should not exceed 50 o/o.

Adding of kerosene to No. 1-D diesel
fuel is not recom m ended even at low
tem peratures.
Warning!
Always follow basic safety rules when
w orking with any com bustible m ater
ial. Do not fill the fuel tank or mix
diesel fuel and kerosene when sm ok
