FUEL RECOMMENDATIONS
WARNING
Diesel fuel is combustible and can
cause severe personal injury or death. Do not
smoke near fuel tanks or fuel-burning equip-
ment or in areas sharing ventilation with such
equipment. Keep flames, sparks, pilot flames,
electrical arcs and switches and all other
sources of ignition well away. Keep a multi-
class ABC fire extinguisher handy.
High quality diesel fuel is necessary for good perfor-
mance and long engine life.
• The specifications for the type and sulfur con-
tent (ppm, % weight) of the diesel fuel used
must comply with all emissions regulations ap-
plicable in the areas where the genset is to be
operated.
• Diesel fuels meeting ASTM D975 or EN 590
specifications are recommended. Use Grade
1-D diesel fuel where ambient temperatures
are below 14° F (−10° C). A minimum Fuel Ce-
tane Rating of 45 is recommended. Where am-
bient temperatures are below −4 F (−20° C), or
the elevation is above 5000 ft (1500 m), a mini-
mum Cetane Rating of 50 is recommended.
• Current US EPA regulations for Non-Road en-
gines limit diesel fuel sulfur content to a maxi-
mum of 500 ppm (0.05% weight). Therefore,
use Grade 2-D S500 or 2-D S15 diesel fuel.
Where ambient temperatures are below 14° F
(−10° C), use Grade 1-D S500 or 1-D S15 die-
sel fuel. Note that beginning in year 2010, US
EPA regulations for Non-Road engines will limit
diesel fuel sulfur content to a maximum of 15
ppm (0.0015% weight).
• Do not use diesel fuel having a sulfur content
greater than 10,000 ppm (1.0% weight).
• Diesel fuel must meet the ASTM D975 stan-
dard for lubricity and pass a minimum load level
of 3100 grams as measured by ASTM D6078,
or maximum scar diameter of 0.45 mm as mea-
sured by ASTM D6079 or ISO 12156−1.
• B5 Bio-Diesel fuel that meets industry specifi-
cations and quality is suitable for use with this
genset.
ENGINE OIL RECOMMENDATIONS
Oil Performance Class
Use API (American Petroleum Institute) classified
engine oils according to the following guidelines:
• Emissions-Regulated Areas: It is mandatory
to use CF, CF−4, CG−4, CH−4 or CI−4 class oil
with low sulfur fuel (sulfur content less than 500
ppm, 0.05% weight) or ultra low sulfur fuel (sul-
fur content less than 15 ppm, 0.0015% weight).
• Non-Regulated Areas: CF class oil is recom-
mended when using high sulfur fuel—sulfur
content between 500 ppm (0.05% weight) and
5000 ppm (0.5%weight). If CF−4, CG−4, CH−4
or CI−4 class oil is used, the oil and oil filter
must be changed twice as often as specified in
the PERIODIC MAINTENANCE SCHEDULE
(Page 3-1).
• Non-Regulated Areas: Use CF, CF−4, CG−4,
CH−4 or CI−4 class oil when using high sulfur
fuel—sulfur content between 5000 ppm (0.5%
weight) and 10,000 ppm (1.0% weight). The oil
and oil filter must be changed twice as often as
specified in the PERIODIC MAINTENANCE
SCHEDULE (Page 3-1).
Oil Viscosity
Look for the SAE (Society of Automotive Engineers)
viscosity grade. Referring to Figure 2-1, choose the
viscosity grade appropriate for the ambient temper-
atures expected until the next scheduled oil change.
Multi-grade oils such as SAE 15W-40 are recom-
mended for year-round use.
