RECOMENDED ENGINE OIL & FUEL
KUBOTA D1105 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 tem-
peratures, 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 cleanli-
ness 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.
