NOTE
Engine Oil:
• Oil used in the engine should have an American Petroleum Institute (API) service classification and
Proper SAE Engine Oil according to the ambient temperatures.
Above 25 °C (77 °F)
0 to 25 °C (32 to 77 °F)
Below 0 °C (32 °F)
• Refer to the following table for the suitable API classification engine oil and the fuel.
Fuel used
Ultra Low Sulfur Fuel [< 0.0015 % (15 ppm)]
Fuel:
• Use the ultra low sulfur diesel fuel only [below 0.0015 % (15 ppm)] for these engines.
• Cetane number of 45 minimum. Cetane number greater than 50 is preferred, especially for temperatures below
-20 °C (-4 °F) or elevations above 1500 m (5000 ft).
• Diesel fuels specified to EN 590 or ASTM D975 are recommended.
• No. 2-D is a distillate fuel of lower volatility for engines in industrial and heavy mobile service. (SAE J313 JUN87)
• Indicated capacities of water and oil are manufacture's estimate.
IMPORTANT
• If you use different fuel or engine oil, the cleaning interval of the DPF (3000 hours) can't be secured and
the DPF will be clogged for a shorter time than expected.
• Filters must trap fuel and lubricant sulfate additives (Zn, Pb, Na, K, Ca, Mg, Cu, Ba, P, etc.) as ash during
combustion. Fuel must be controlled carefully to prevent the additives being mixed into fuel such as fuel
tank anti-oxidants, water remover, anti-freeze and so on.
