<For North American market>
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 :
• 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).
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 tractor.
Fuel
• Cetane number of 45 minimum. Cetane number greater then 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 engine 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 delivers 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.
