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:
A
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).
C
Fuel:
A
Cetane number of 45 minimum. Cetane number greater than 50 is preferred, especially for temperatures below
-20
(-4
) or elevations above 1500 m (5000 ft).
A
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%.
A
DO NOT use diesel fuel with sulfur content greater than 1.0%.
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)
A
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
(14
).
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.
(Consult your local KUBOTA Dealer for further detail.)
Do not mix different brands together.
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 internal
EGR, external EGR or non-EGR) and the fuel (low-sulfur or high-sulfur fuel).

used with a high-sulfur fuel, change the lubricating
