Engine oil
NOTE
• Refer to the following table for the suitable American Petroleum Institute (API) classification of engine oil
according to the engine type and the Fuel Type.
Fuel type
Ultra low sulfur fuel
Sulfur content <0.0015% (15 ppm)
• Engine oil should be API classification CJ-4 or CK-4.
• Change the type of engine oil according to the ambient temperature.
• When using oil of different brands from the previous one, be sure to drain all the previous oil before
adding the new engine oil.
• On DPF-equipped engines, part of the fuel may get mixed with engine oil during the regenerating process.
This may dilute the oil and increase its quantity.
If the oil rises above the oil level gauge upper limit, it means the oil has been diluted too much, resulting
in a trouble.
In such case, immediately change the oil for new one.
• If the interval of DPF regeneration becomes 5 hours or less, be sure to change the oil for new one.
Fuel
NOTE
• The minimum recommended Fuel Cetane Rating is 45.
A cetane rating greater than 50 is preferred, especially for ambient temperatures below -20 ℃ (-4 ℉) or
elevations above 1500 m (4921 ft).
• Diesel fuel specification type and sulfur content% (ppm) used, must be compliant with all applicable
emission regulations for the area in which the engine is operated.
• DO NOT USE Fuels that have sulfur content greater than 0.0015% (15 ppm).
• Diesel fuels specified to EN590 (0.001% (10 ppm) sulfur maximum) or ASTM D975 (0.0015% (15 ppm)
sulfur maximum) are recommended.
• No. 2-D is a distillate fuel of lower volatility for engines in industrial and heavy mobile service (SAE J313
JUN87).
• These engines utilize Interim Tier 4 standards, the use of ultra low sulfur fuel is mandatory for these
engines, when operated in US EPA regulated areas.
Therefore, please use No. 2-D S15 diesel fuel as an alternative to No. 2-D, and use No. 1-D S15 diesel fuel
as an alternative to No. 1-D for ambient temperature below -10 ℃ (14 ℉).
– SAE: Society of Automotive Engineers
– EN: European Norm
– ASTM: American Society of Testing and Materials
– US EPA: United States Environmental Protection Agency
– No. 1-D or No. 2-D, S15: Ultra Low Sulfur Diesel (ULSD) 15 ppm or 0.0015 wt.%
IMPORTANT
• Be sure to use a strainer when filling the fuel tank, or dirt or sand in the fuel may cause trouble.
• Do not operate the fuel tank level too low or completely out of fuel.
You may experience improper engine operating and/or a DTC (Diagnostic Trouble Code) error code may
be recorded in the Engine Control.
Additionally, fuel system bleeding may be necessary if air enters the fuel system.
Biodiesel fuel
[When the B7 blended fuel is used]
When the finally blended Biodiesel fuel is B7, make sure it conforms to the updated EN590 (European) standard.
Be also sure that the mineral oil diesel fuel, if used, conforms to the updated EN590 (European) standard and that the
B100 blend conforms to the updated EN14214 (European) standard.
