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
(≥ 500 ppm)
Low Sulfur Fuel (< 500 ppm)
or Ultra Low Sulfur Fuel
(< 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 tractor.
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 % sulfur content is used, reduce the service interval for engine oil
and filter by 50 %.
• DO NOT use diesel fuel with sulfur content greater than 1.0 %.
• 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)
• Since this engine adopts EPA Tier 4 and Interim Tier 4 standards, the use of low sulfur fuel or ultra low sulfur fuel
is mandatory in EPA regulated area (North America). Therefore, please use No. 2-D S500 or S15 diesel fuel as
an alternative to No. 2-D, or use No. 1-D S500 or S15 diesel fuel as an alternative to No. 1-D if outside air
temperature is below -10 °C.
• Transmission Oil:
The oil used to lubricate the transmission is also used as hydraulic fluid. To insure proper operation of the hydraulic
system and to complete lubrication of the transmission, it is important that a multi-grade transmission fluid is used in
this system. We recommend the use of KUBOTA UDT or SUPER UDT fluid for optimum protection and
performance.
Do not mix different brands together.
• Indicated capacities of water and oil are manufacture's estimate.
