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 as shown above:
• With the emission control now in effect, the CF-4 and CG-4 lubricating oils have been developed for use
of a low-sulfur fuel on on-road vehicle engines. When an off-road vehicle engine runs on a high-sulfur
fuel, it is advisable to employ the "CF or better" lubricating oil with a high Total Base Number (TBN of
10 minimum).
• Refer to the following table for the suitable API classification engine oil according to the engine type (with
internal EGR, external EGR or non-EGR) and the fuel (low-sulfur or high-sulfur fuel).
Fuel used
High Sulfur Fuel
[≥ 0.05 % (500 ppm)]
Low Sulfur Fuel
[< 0.05 % (500 ppm)]
or Ultra Low Sulfur
Fuel
[< 0.0015 % (15 ppm)]
EGR: Exhaust Gas Re-circulation
• The CJ-4 engine oil is intended for DPF (Diesel Particulate Filter) type engines, and cannot be used on this
machine.
Models
Fuel:
• Cetane number of 45 minimum. Cetane number greater than 50 is preferred, especially for temperatures below
−20 °C or elevations above 1500 m.
• If diesel fuel with sulfur content greater than 0.5 % (5000 ppm) sulfur content is used, reduce the service interval
for engine oil and filter by 50 %.
• NEVER use diesel fuel with sulfur content greater than 0.05 % (500 ppm) for EXTERNAL EGR type engine.
• DO NOT use diesel fuel with sulfur content greater than 1.0 % (10000 ppm).
• 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)
Transmission Oil:
*KUBOTA Super UDT-2: For an enhanced ownership experience, we highly recommend Super UDT-2 to be used
instead of standard hydraulic/transmission fluid.
Super UDT-2 is a proprietary KUBOTA formulation that deliveries superior performance and protection in all
operating conditions.
Regular UDT is also permitted for use in this machine.
• Indicated capacities of water and oil are manufacturer's estimate.
