C Engine Oil:
A 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:
C Fuel:
A Use the ultra low sulfur diesel fuel only [below 0.0015% (15 ppm)] for these engines.
A Cetane number of 45 is minimum. Cetane number greater than 50 is preferred, especially for temperatures below
-20 (-4 ) or elevations above 1500 m (5000 ft).
A Diesel fuels specified to EN 590 or ASTM D975 are recommended.
A No.2-D is a distillate fuel of lower volatility for engines in industrial and heavy mobile service. (SAE J313 JUN87)
C 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.
A Indicated capacities of water and oil are manufacturer's estimate.
A Refer to the following table for the suitable API classification engine oil according to the engine type
(with DPF or non-DPF (Diesel Particulate Filter) type engines) and the fuel.
A The CJ-4 engine oil is intended for DPF (Diesel Particulate Filter) type engine.
