Use only diesel fuels conforming to the following
recommendations, without any additives, for diesel
engines installed in Mitsubishi Fuso trucks.
1 Diesel-fuel properties
The following recommendations concerning diesel
fuel used with Mitsubishi Fuso diesel engines are
given for optimum fuel economy and performance.
Use condition
Normal operation at
temperatures above
–12°C (10°F).
Operation at tempera-
tures below –12°C
(10°F), or long-hour no-
load operation.
Biodiesel fuel can be used if it has a 5% or lower
blend ratio and complies with ASTM D-6751.
NOTE:
* ASTM is an acronym for the American Society for
Testing and Materials which recommends fuel con-
taining 0.0015% – basis 15 ppm sulfur or less sulfur
content.
Note that a sulfur content exceeding 0.0015% –
basis 15 ppm sulfur deteriorates the performance of
emission control device.
To meet fuel requirements, it is necessary to obtain
cooperation from a reputable fuel oil supplier. Both
fuel suppliers and users are responsible for keeping
fuel clean.
2 Diesel fuel to be used in your engine
Use only a ultra low sulfur diesel fuel (with a sulfur
content of 15 ppm or lower) for refueling your Mitsu-
bishi Fuso diesel engine. Otherwise, the catalyst
inside the diesel particulate filter (DPF) will not work
effectively and the DPF's performance of removing
small particles (particulate matter or PM) in exhaust
gases will be degraded. Furthermore, your truck will
not meet emission regulations if you replenish it
with a non-approved fuel.
