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
ultra low sulfur fuel is mandatory for these engines, when operated in US EPA regulated areas. Therefore, please use
No.2-D S15 diesel fuel as an alternative to No.2-D, and use No.1-D S15 diesel fuel as an alternative to No.1-D for
ambient temperatures below -10
