1 Engine oil
Performance, life, and startability of the engine
depend to a large degree on the engine oil. Always
use oil of the specified grade and viscosity.
The proper engine oil viscosity numbers for various
atmospheric temperature ranges are shown in the
diagram.
The first engine oil replacement during the run-in
period should be performed at the first 4,000 km
(2,500 miles).
CAUTION
Replace the engine oil earlier if the engine is fre-
quently used at high speeds or under high load-
ing.
Recommended lubricant:
Engine oil
API classification CJ-4
SAE40, 10W-30, 15W-40
CAUTION
•
Use only the specified engine oil. Any other
oils may contain substances that cause the
ceramic filter inside the DPF to be loaded
with particulate matter (PM) prematurely to
the capacity and thus shorten the effectively
functioning period of the DPF.
•
Change the engine oil at the specified inter-
vals. During the regeneration process of the
DPF, part of the fuel may mix into the engine
oil while the PM is being removed by oxida-
tion. If the engine oil is not changed at the
specified intervals, it may excessively deteri-
orate due to mixing of fuel and could cause
engine failure. In the worst case, the engine
could spontaneously run at an abnormally
high speed.
