RECOMMENDED ENGINE OIL & FUEL
KUBOTA D905 DIESEL ENGINE
Engine oil should be MIL-L-2104C or have properties of API classification of CD grades
or higher.
Change the type of engine oil according to the ambient operating temperature:
Above 77°F (25°C) SAE 30
32°F to 77°F (0 to 25°C) SAE 20
Below 32°F (0°) SAE 10W
SAE 10W-30
Use #2 diesel fuel.
NOTES:
1. The temperatures in the table are the ambient temperatures at the time when the
engine is started. If the running ambient temperatures are much higher than the
starting temperatures, a compromise must be struck and a higher
viscosity oil used. Multi-grade oils overcome the problem, provided they possess
a suitable specification.
2. MIL-L-2104B or MIL-L-2104C or API CD must also be used if the sulfur content
of the fuel exceeds 0.5%.
3. Always use a reputable brand of diesel fuel. The sulfur content should be below
0.5% (higher sulfur content would require more frequent oil changes). Observe
strict cleanliness when filling the fuel tank.
4. Check the engine oil level before starting the engine or more than five minutes
after it has been stopped. Remove the dipstick, wipe clean, reinsert it, take it out
again, and check the oil level. If the oil level is too low, remove the oil filler cap
and add new oil until the FULL line on the dipstick is reached.
