Lubricating oil
With strict emission control regulations now in effect, the CF-4 and CG-4 engine oils have been developed for use with
low sulfur fuels, for On-Highway vehicle engines. When a Non-Road engine runs on high sulfur fuel, it is advisable to
use a "CF or better" classification engine oil with a high Total Base Number (a minimum TBN of 10 is recommended).
A Lubricating oil recommended when a low-sulfur or high-sulfur fuel is employed.

**Fuel
A Diesel Fuel Specification Type and Sulfur Content % (ppm) used, must be compliant with all applicable emission
regulations for the area in which the engine is operated.
A Use of diesel fuel with sulfur content less than 0.10 % (1000 ppm) is strongly recommended.
A If high-sulfur fuel (sulfur content 0.50 % (5000 ppm) to 1.0 % (10000 ppm)) is used as a diesel fuel, change the engine
oil and oil filter at shorter intervals. (approximately half).
A DO NOT USE Fuels that have sulfur content greater than 1.0 % (10000 ppm).
A Since KUBOTA diesel engines of less than 56 kW (75 hp) utilize EPA Tier 4 and Interim Tier 4 standards, the use of
low sulfur fuel or ultra low sulfur fuel is mandatory for these engines, when operated in US EPA regulated areas.
Therefore, please use No.2-D S500 or S15 diesel fuel as an alternative to No.2-D, and use No.1-D S500 or S15 diesel
fuel as an alternative to No.1-D for ambient temperatures below -10 C (14 F).
1) No.1-D or No.2-D, S500 : Low Sulfur Diesel (LSD) less than 500 ppm or 0.05 wt.%
No.1-D or No.2-D, S15 : Ultra Low Sulfur Diesel (ULSD) 15 ppm or 0.0015 wt.%
A CJ-4 classification oil is intended for use in engines equipped with DPF (Diesel Particulate Filter) and is Not
Recommended for use in Kubota E3 specification engines.
A Oil used in the engine should have API classification and Proper SAE Engine
Oil according to the ambient temperatures as shown below:
Above 25 (77 ) SAE30, SAE10W-30 or 15W-40
0 to 25 (32 to 77 ) SAE20, SAE10W-30 or 15W-40
Below 0 (32 ) SAE10W, SAE10W-30 or 15W-40
A Recommended API classification
Refer to the following table for the suitable American Petroleum Institute (API) classification of engine oil according to
the engine type (with internal EGR, external EGR or non-EGR) and the Fuel Type Used : (Low Sulfur, Ultra Low Sulfur
or High Sulfur Fuels).
Fuel type
High Sulfur Fuel CF
[0.05 % (500 ppm) (If the "CF-4, CG-4, CH-4 or CI-4" engine oil is used
Sulfur Content < with a high-sulfur fuel, change the engine oil at
0.50 % (5000 ppm)] shorter intervals. (approximately half))
Low Sulfur Fuel
[Sulfur Content <
0.05 % (500 ppm)] or
CF, CF-4, CG-4, CH-4 or CI-4
Ultra Low Sulfur Fuel
[Sulfur Content <
0.0015 % (15 ppm)]
