Diesel Fuel Additives in Vehicles Cer­
tified for California Operation
Beginning with 1985 models, this
vehicle with California-Version Diesel

dizer. If you use non-approved fuel
additives, the Trap Oxidizer could be
damaged, resulting in severe engine
power loss and expensive repairs, not

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 must not be
used.
At very low temperatures the fluidity
of No. 2-D diesel fuel may become
insufficient due to paraffin separation.
To avoid malfunctions, No. 2-D diesel
fuel of a lowered cloud point is
marketed 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 ra­
tios shown refer to the total mixture.
