LUBRICANTS, FUEL AND COOLANT
Fuel:
• 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).
• 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)
• If the engine is to be operated within the European Union on diesel or non-road gas-oil, a fuel with sulfur content
lower than 10 mg/kg (20 mg/kg at point of final distribution), a cetane number greater than 45 and a fatty acid
methyl ester (FAME) content lower than 7 % volume per volume (v/v) shall be used.
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 in the previous table.
• Refer to the following table for the suitable API classification engine oil according to the engine type (with Diesel
Particulate Filter (DPF) type engines) and the fuel.
Ultra low sulfur fuel
<0.0015 % (15 ppm)
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 oil.
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.
